Answer:
1. Homeostasis
2. Organ system
3.The bones of the skeletal system serve to protect the body's organs, support the weight of the body, and give the body shape. The muscles of the muscular system attach to these bones, pulling on them to allow for movement of the body.
4.The nervous and endocrine systems are two forms of communication system in the human body that integrate, coordinate and respond to sensory information which is received by the human body from its surroundings
5.The skin functions by protecting the body from basic elements of nature such as water, UV sunlight and wind. ... However, skin in integumentary system acts by maintaining the internal conditions that is required by the body while it is excretory system because it secretes a fluid waste called sweat or perspiration.
6.In order to survive, cells must satisfy some basic needs such as oxygen, water, nutrients, waste removal, and maintaining of homeostasis. Oxygen and nutrients are necessary for different processes inside the cell. For instance, cellular respiration uses glucose and oxygen to form energy in the form of ATP.Water is important for different chemical reactions, as well. Also, the result of different processes, waste is produced and it is important to remove it from the cell. Finally, it is important that cell and whole body conditions do not vary so much and that homeostasis is maintained.
7.Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (rRNA). Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.
8. the body is not in homeostasis from 7 to 10 hours. Explanation: The given graph shows homeostasis in terms of body temperature. The normal body temperature, that is 37 degrees C is maintained from 1 to around 6:45 hours.
9.There are several reasons why the body temperature falls continuously just like when you are exposed to an extreme cold weather or wearing wet clothing for a long time. This abnormality state of the body temperature can lead into some potential diseases and disorders like infection, insomnia, stress and sepsis
10.Sweating also hydrates your skin and maintains the balance of electrolytes in your body. The fluid you sweat comprises mainly salt and water. Excessive sweating can cause dehydration since you lose a large amount of water. The technical term for excessive sweating is hyperhidrosis.

In other words, how are we speeding up the effects of the competitive exclusion principle and thereby altering the outcome of that ecosystem's natural succession
Answers
Answer: Overgrazing, overfishing, and forest fires
Explanation:
Competitive exclusion principle two species which have the same ecological niche cannot exists together as such species will be competing for the same resources. The species which is superior over the other will receive the resources and the other species having no competitive advantage will not survive in future.
According to the given situation, human being is the most superior species on earth and have competitive advantage of thinking ability and intelligence over other species. Succession are the changes that occur in the biotic community of an ecosystem with respect to time.
The human beings can speed up the effects of the competitive exclusion principle by various ways: Overgrazing, overfishing, and forest fires. The overgrazing of the cattle in the field can remove the vegetation cover of the region and the land will become barren so instead of progressive succession in terms of vegetation cover the succession will again re-initiate in terms of primary succession if environment supports.
Overfishing can cause the exclusion of some valuable species of fish and there will not be evolution of such species and will alter the outcome of natural succession.
Forest fires can affect both floral and faunal species some species may tolerate the fire and will survive and some precursors like roots of the plants can support new individual plants. This will again alter the outcome of natural progressive succession in an ecosystem.

4. Take a beaker (jar or jug) with some water and put some drops of red or blue
ink in it. Take a tender twig of any flowery plant with leaves and flowers, preferably
white flowers, and put it in the beaker for 6 to 8 hours. What do you observe? For
further examination cut across its stem and look for the presence of colored water.
Explain your observations.
Answers
Answer:
Blue Ink patches are observed on the leaves of the plant. Also, on cutting across the stem of the plant, the red color of the solution is found along the length of the stem.
The above observation shows that the stem of the plant conducts water through its length to the leaves of the plant.
Explanation:
The leaves of plant obtain water and minerals from the soil through the roots of the plant. The water is conducted by the stem of the plant from the roots to the leaves of the plant where they are needed for photosynthesis as well as for cooling the plant. The xylem tissue in plants is responsible for conducting water to the leaves of the plant from the roots of the plant through the stem.
The conduction of water from the roots to the leaves of the plant is maintained by capillary action as well as by transpiration pull. Transpiration pull refers to the pull of water by the transpiration action taking place in the leaves of the pant, whereby water evaporates from the leaves of the plant through the opening in the leaf of the plant.
When the blue ink is added to the water, the colored water is conducted through the stem of the plant to the leaves. On getting to the leaves, the water molecules evaporate leaving behind the colored patches fond on the leaves. When the stem of the plant is cut, the blue color is seen along its length showing that the colored water was conducted through it.
What happened if we add normal saline instead of PBS during beta amylase extraction?
Answers
Answer:
hi
Explanation:
Saline is the solution of water and NaCl does not provide the appropriate pH, so enzyme activity is lost, we cannot add saline instead of PBS during beta amylase extraction.
How saline water affects beta amylase extraction?PBS (phosphate buffer solution) is a type of buffer that is suited for beta-amylase activity, which implies that when beta-amylase is extracted using buffer, the enzyme's chemical activity is kept.
When we utilize saline, which is a solution of water and NaCl, the pH of the solution is not acceptable, and the enzymes' chemical activity is destroyed.
As a result, for enzyme/protein extraction, we always employ a buffer solution, which maintains the ph for the proper functioning of an enzyme.
Therefore due to pH conditions enzyme lost activity, and normal saline water can not be used instead of PBS for extraction of beta-amylase.

What's the exact path of a deoxygenated blood cell?
The question:
Trace a deoxygenated Red Blood Cell from your leg muscle on its path to picking up oxygen and then bringing some oxygen to the brain. Continue to trace that same RBC from the brain then to supply the bicep muscle with oxygen.
Answers
Answer:
This is the pathway of the RBC from the leg into the brain and then to the bicep muscle.
Explanation:
The RBC in the leg with run up from the axillary vein into the inferior vena cava into the right atria. Then it is pumped into the right ventricle and is pumped into the pulmonary arteries to the lungs. The RBC meets the alveoli in the lungs, through the capillaries, and Type 1 cells help with the gas exchange of Carbon Dioxide and Oxygen into the RBC. The RBC then travels up and to the pulmonary veins into the left atria of the heart. It them gets pumped into the left ventricle where it is pumped up the aortic trunk and travels through the either the brachiocephalic trunk into the right common carotid artery or enters the right common carotid artery. The artery then bifurcates into the left/right internal common carotid and then supplies the brain with oxygen. It then runs back into the superior vena cava, into the right atria, into the right ventricle, and back to the pulmonary arteries. Then to the alveoli, and to the pulmonary veins. Then the RBC with enter the left atria and then enter the left ventricle and be pumped into the aortic arch and enter either the brachiocephalic trunk or enter the left subclavian artery and will enter into the brachial artery, which supplies the bicep muscle with blood, and will drop the oxygen at the bicep muscle.

In cucumbers, dull fruit (D) is dominant to glossy fruit (d), and orange fruit (R) is dominant to cream-colored fruit (r). The gene that codes for dull versus glossy assorts independently from the gene that codes for orange versus cream-colored. A plant that has dull and orange fruits is crossed to a plant that has dull and cream-colored fruits. The cross produces eight total progeny, with three plants that have dull and orange fruits, three plants with dull and cream-colored fruits, one plant with glossy and orange fruits, and one plant with glossy and cream-colored fruits.
Determine progeny phenotypic ratios - texture. To determine the actual genotype of the parents from among the possible genotypes identified in the previous step, separate the cross into two single-locus crosses, looking at the inheritance of each trait by itself.

Answers
Answer:A) Patau Syndrome (Trisomy 13) causes intellectual and physical disability, such as underdeveloped eyes, extra fingers/toes, heart defects. Survival beyond the first year is uncommon.
B)
Explanation: Trisomy (or aneuploidy in general) can result when chromosomes to do not separate correctly during mitosis or meiosis. In meiosis, non-separation of a chromosome pair results in a gamete with two copies of the chromosome (and consequently one gamete lacking the chromosome.
At fertilisation the embryonic cell will have three copies of the chromosome (and an embryonic cell with one copy only). These are serious mutations, many of which are non-viable and usually abort spontaneously. Others results in abnormal development and poor survival rates. Only one autosomal trisomy (21) and sex chromosome trisomies (XXX, XXY etc) result in babies that survive into adulthood, albeit with physical and developmental abnormalities (trisomy 21 abd trisomy X). Only one monosomy (XO) is viable.
Other mutations can be less inimical, and may not result in any variation from normal. Mutations in genes coding for proteins or ribosomes may result in potential loss of function. As there are two copies of each gene, the mutated gene is paired with a normal gene and if that is expressed there will be no loss of function.
There are cases where the mutated gene is dominant it will change the phenotype. An example is Marfan Syndrome, an autosomal (chromosome 15) dominant mutation resulting in connective tissue abnormalities and long bones.
An autosomal recessive mutation is not expressed but is carried. If both parents are carriers, the probability of offspring to be doubly recessive and have an altered phenotype is 25%. Cystic fibrosis is an example.
A third possibility is where two alleles are co-dominant. An example of this is sickle cell disease. Consider the three allele pairs SS, Ss and ss.
Those with ss have sickle cell anaemia, a painful and debilitating condition. Those with SS have normal blood cells. Those with Ss have sickle cell trait, which has some mild deficits because a proportion of blood cells are abnormal.

Mr. Morales is teaching a lesson on classification. He says that spiders are classified as a different group than insects because they have eight legs instead of six legs. He explains that spiders evolved first. Mr. Morales also says that having eight legs is the derived trait that separates the two groups. Antonio thinks Mr. Morales is wrong. Which piece of information is Antonio considering?
A.Spiders do not have eight legs.
B.Insects do not have six legs.
C.If spiders evolved first, six legs is the derived trait.
D.Spiders do not have derived traits, since they evolved first.
Answers
Answer: The answer is C
Explanation:
The piece of information that Antonio is considering is that if spiders evolved first, six legs are the derived trait. So the correct option is C.
What are derived traits?A trait that has been observed in a group of organisms but was not observed or was absent in the previous common ancestor of the group.
These are also the traits that are not present in the group of organisms under consideration but were observed in the previous common ancestors. This is called the secondary loss of traits.
Therefore, derived traits are not only concerned with the development of new traits but also the loss of old traits. Simplicity in a structure or function is a secondary derived trait.
Thus, because the spiders evolved before other insects, the presence of 6 legs in insects is a secondary derived trait as it represents simplicity in structure. Spiders are not derived because they are the common ancestors of the group of insects.
Therefore the correct option is C.
