Compare and contrast disorganized schizophrenia and paranoid schizophrenia.
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions. In the disorganized one appears a behavioral disorganization and of the thought and language as well as an inappropriate affect. These patients tend to have an earlier onset, a worse prognosis, and a greater number of neurocognitive alterations.
Explanation:
Paranoid schizophrenics are characterized by sharp delusions, especially persecution ideas of grandeur, often with a corresponding aggressive reaction in response to the alleged persecution. There may be hallucinations of various kinds, to which patients react consecutively, but later, as deterioration occurs, apathy and indifference appear. Hallucinations are common. On the other hand, disorganized schizophrenia is another form of schizophrenia that is characterized by disorganization of speech, that is, the language is rambling and incoherent, the behavior is unpredictable, inappropriate and incongruous.
Answer:
The paranoid subtype is characterized by the presence of hallucinations and delusions. In the disorganized one appears a behavioral disorganization and of the thought and language as well as an inappropriate affect.

How many objects must be present in a system to demonstrate gravity as a force of attraction?
Answer:
Explanation:
Knowing the value of G allows us to calculate the force of gravitational attraction between any two objects of known mass and known separation distance. As a first example, consider the following problem.
In the ELISA procedure, first a protein sample is immobilized to a plastic well. Then, the antibody to the protein of interest is added, incubated, and the excess is washed out. Next, the detection antibody (which binds to the primary antibody) is added, incubated, and the excess is washed out. The last step is to add the detection dye (which binds to the detection antibody) to the wells and allow it to incubate. What do you predict the result would look like if you added the detection antibody first, then the antibody to the protein of interest
Answer:
In this ELISA procedure, a sample of protein is immobilized in the plastic well and then antibody for this protein added and incubated, and cleared out. In the given setting detection, the antibody is conjugated with the protein of interest and if the substrate molecule added to the reaction it will produce a colored product by reacting with the enzyme.
No reaction will take place in the well in case of not adding secondary antibody or detection antibody to the reaction and no colored product will be received.
Why does the mass of a substance remain the same after a chemical reaction
Answer:
Even in a chemical reaction when atoms interact and create new products, mass is conserved. This is because the new substances created are composed of atoms that were present in the reactants. The atoms from the reactants come apart, rearrange, and re-bond in a different arrangement to form the products.

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply. (10 points)
Scenario 1:
Genetic engineering can be used to create more productive strains of farm animals. By adding genes to an animal's DNA, the animal can be made to produce milk or meat containing vital nutrients that would not be found naturally in those products. This provides a greater amount of nutrients per serving of milk or meat.
Do you think that this type of genetic engineering should be pursued? Explain your answer. (5 points)
What are some possible impacts (positive and negative) of this type of genetic engineering on individuals, society, and the environment? (5 points)
Scenario 2:
In the future, doctors may be able to evaluate your DNA to check for genetic markers related to specific medical conditions or harmful reactions to medications. Your personalized genetic profile could be kept on record and referred to in order to develop personal medical treatment based on your unique DNA sequencing. Scientists have found that just small variations in a specific section of your DNA can help determine how well some medications can work for you or if they would be beneficial at all.

Answer:
i tried my best (so many questions on scenario 2)
Explanation:
scenario 1: there are many positive and negative possible impacts that come with genetic engineering. A very negative outcome could come from just one mistake. But if there was a way to ensure that nothing could go wrong than the outcome would be an healthy new meat or milk that's packed with nutrients.
scenario 2: I think if this was a real thing i would be completely for it. If a person was to get their DNA checked then doctors would be able to prescribe a medication that would fit you. this could also prevent any allergic reactions to and medications or treatments.
I personally would want my DNA profile kept on record so that i can be treated with the right medications for me.

(2)
(2)
(12)
Answer:
The correct answer is -
1.1 A. herbivore - greenfly
b. producer - rose
1.2. 1 kJ/m2/year
1.3 rose plants will increase, ladybirds will decrease, blackbirds will decrease.
Explanation:
In this food chain,
Rose >>Greenfly >>Ladybird >>Blackbird
Rose plants are the producers as they generate their food and energy and does not depend on other organisms where as greenfly are the primary consumer or herbivore as they depend on the rose plant for their food and energy only, however, ladybird as secondary consumer and blackbird as tertiary consumer depend on greenfly and ladybird respectively.
If rose plants have 1000 kJ/m2 /year of energy and as it is known that only 10% moves to the next tropic level then blackbird would have:
rose = 1000
greenfly = 1000*10/100= 100 kJ
ladybird = 100*10/100 = 10kJ
blackbird = 10*10/100 = 1 kJ
If greenfly removes from here the rose plant will increase as these depends and eat rose plants and lady bird will decrease as these are the primary source of food for lady bird and if ladybird decrease blackbird also decrease.

Which of the following metabolic pathways does NOT directly produce lots of ATP (also called anaerobic cycle)?
A. Glycolysis
B. Krebs cycle
C. Citric acid cycle
D. Electron transport chain
Answer:
A. Glycolysis
Explanation:
Glycolysis is the first stage of cellular respiration, which occurs in the cytoplasm of the cell. Glycolysis does not require oxygen to occur, hence, it is carried out by both prokaryotic and eukaryotic organism.
Glycolysis, among the other stages of cellular respiration, produces the least ATP (2). Hence, Glycolysis is the metabolic pathway that does NOT directly produce lots of ATP.

b. No……………………………………………………………………………… Order Odonata
6. Does the insect have a small body with large fan –shaped wings?
a. Yes…………………………………………………………………………… Order Lepidoptera
b. No………………………………………………………………………………Order Hymenoptera
Answer:
ORDER ODONATA
Explanation:
It is simple to read a dichotomous key. You only need to understand the technical terminology and to detailed observe your specimen. The key will lead you to the answer.
1. Does the insect have wings?
a. Yes………………………………………………………………………… go to step 2
b. No…………………………………………………………………………. Order Hemiptera
We only need to answer this question by looking at the image. In our example, yes, the insect has wings. So we need to go to question number two. Note: In the hypothetical case that the insect would not have wings, it would belong to the Hemiptera order.
2. Does the insect have parallel wings? (hint: Parallel wings don’t stick out to the side)
a. Yes……………………………………………………………………………… go to step 3
b. No………………………………………………………………………………. go to step 4
Ok, here it tells you that parallel wings do not stick out to the side. But in our example, wings do stick out, so the answer should be NO. This species does not have parallel wings. As it is a NO, we go to question number 4.
Note: In the hypothetical case that the insect would have parallel wings, we should read number 3.
4. Does the insect have 4 total wings?
a. Yes………………………………………………………………………………… go to step 5
b. No………………………………………………………………………………… Order Diptera
This one is easy. How many wings our specimen has? Four. Then it is a YES, and we go to question number 5. Note: In the hypothetical case that the insect would not have 4 wings, it would belong to the Diptera group.
5. Does the insect have long antennae?
a. Yes………………………………………………………………………………go to step 6
b. No……………………………………………………………………………… Order Odonata
Our insect has very short antennae. They are not long at all. So, the answer is NO, the insect does not have long antennae. This answer leads us directly to the order of our individual. ORDER ODONATA. Note: In the hypothetical case that the insect would have long antennae, we should read question number 6. And so on until we would reach the order.
ORDER ODONATA:
Dragonflies belong to this group. These insects characterize as having big eyes, and the separation between them depends on the species. They have an elongated abdomen, sometimes even longer than the wings. Their bodies must be robust to support the massive musculature that propels the wings during flight. The wings are long, big, and wide.
Usually, the males are much more colored than the females are.

A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. Look at the biomass pyramid to the right. Based on the data shown, how many kilograms of plant matter would be needed to support the other trophic levels in this ecosystem?
Answer:
90,000
Explanation:
A pyramid of biomass shows the mass of all of the organisms in each trophic level of an ecosystem. From the biomass pyramid to the upright ladder, the kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.
In ecology, the biomass pyramid is a graphical representation designed to show the quantity of biological or organic matter observed in an organism.
The ecological biomass pyramid starts with the primary producer which is usually a green plant.
Followed by the herbivores(animals that feed) on the green plants. They are the primary consumers. The carnivores are secondary consumers that feed on herbivores. Then the peak of the pyramid is the tertiary consumers which are called omnivores. (i.e animals that feed on plants & animals).The amount of mass consumed by the primary consumer is equivalent to the total amount of mass in the primary consumer. However, as we go up the pyramid, the mass depreciates.
Therefore, we can conclude that the amount of kilograms of plant matter needed to support the other tropic levels in this ecosystem is 9000 kg.

You have been hired as a field assistant for a researcher interested in the evolution of flower characteristics in orchids. Complete an experiment that determines whether color, size, shape, scent, or amount of nectar is the most important factor in attracting pollinators to a particular species. Assume that you can change any flower's color with a dye and that you can remove petals or nectar stores, add particular scents, add nectar by injection, or switch parts among species by cutting and gluing. Match the terms in the left column to the appropriate blanks in the sentences on the right. Not all terms will be used.
a. one characteristic.
b. pollination success.
c. aiters others characteristics.
d. affects pollination success the most.
e. has no effect on pollination.

2. Record any measure of____.
3. Repeat for flowers with changed all characteristics other characteristics no characteristics alters other characteristics This characteristic will be____.
4. Analyze the data to determine which altered characteristic____.This characteristic will be the result of the experiment.
Answer:
[tex]\text{Present a flower with one characteristic changed to the normal pollinator. }[/tex][tex]\text{As a control, present a flower with no characteristics changed to the normal pollinator}[/tex]
[tex]\text{Record any measure of pollination success}[/tex]
[tex]\text{Repeeat for flowers with other characteristics changed}[/tex]
[tex]\text{Analyze the data to determine which altered characteristics affect pollination }[/tex][tex]\text{success the most. This characteristic will be the result of the experiment.}[/tex]
Explanation:
The missing information is attached below.
[tex]\text{Present a flower with one characteristic changed to the normal pollinator. }[/tex][tex]\text{As a control, present a flower with no characteristics changed to the normal pollinator}[/tex]
For the control, you'll need something you're already familiar with. In this scenario, a normal flower with no changes in characteristics is the best control. And if no data is accessible, you still have data on the success rate of a typical flower, which can be used as a guideline. And, for the initial configuration, you can only adjust one characteristic so it would be easier to maintain track of and analyze the data gathered.
[tex]\text{Record any measure of pollination success}[/tex]
Since the aim of your experiment is to examine the influence of flower characteristics on pollination performance, you should keep track of the active pollination events. To have more accurate results, this would require listing the total number of plants that were to be pollinated.
[tex]\text{Repeeat for flowers with other characteristics changed}[/tex]
Once you've completed the initial examination, you'll need to run tests on various characteristics to see whether they have some impact on pollination performance. To see the importance of different characters on pollination, change only one trait in flowers; if you'd like to research combined results, create pairs and change them together.
[tex]\text{Analyze the data to determine which altered characteristics affect pollination }[/tex][tex]\text{success the most. This characteristic will be the result of the experiment.}[/tex]
Your outcome is also the one that has gotten the most constructive or negative reviews. If some changed characteristic significantly affected the number of pollination efficiency, that is your outcome, because that is what you can mention as a good result and pollination enhancer.

c. microscopic
d. macroscopic
Match each of the options above to the items below.
1. roundworm, algae
2. protozoan, rickettsia
3. herpesvirus, DNA
4. hydrogen atom, glucose molecule
Answer:
Hydrogen atom & glucose molecule --- atomic.
Herpesvirus, DNA --- ultramicroscopic.
Protozoan, Rickettsia - microscopic.
Roundworm and algae --- macroscopic
Explanation:
1) Hydrogen atom & glucose molecule --- atomic.
The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.
2) Herpesvirus, DNA --- ultramicroscopic.
Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.
3) Protozoan, Rickettsia - microscopic.
Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope. The size range for microscopic particles is [tex]( 10^3 \ \ to \ \ 10^{10})[/tex], which contains protozoans and Rickettsia (a gram-negative, non-motile bacteria genus).
4) Roundworm and algae --- macroscopic

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.
What is corrosion?
The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.
The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.
Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.
Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.
Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.
