The statement "Everyone who carries a faulty allele develops a disease" is absolutely false. This is because some people who carry a faulty allele develop a disease, some are carriers. Thus, the correct option is B.
What is an Allele?An allele may be defined as one or two or more alternative forms of a gene. An individual always inherits two alleles, one from each parent that shows characteristic traits for any given genomic location where such variation exists.
If the two alleles are the same, the individual is homozygous for that allele. While, if the two alleles are non-identical, the individual is heterozygous for that allele.
It is not possible that everyone who carries a faulty allele develops a disease because it depends on the expression of the disease, whether it is dominant or recessive, sexual or autosomal, etc.
Depending on the same principle, some are affected by the disease when both alleles have the same traits while some are carriers.
Therefore, the correct option for this question is B.

Use your knowledge of the mechanism of photosynthesis and the data presented in the chart to determine which of the statements is a correct explanation for the students' data.Group of answer choicesCup 2 had the highest rate of photosynthesis because it had the highest ratio of disks floating to wattage of light.Cup 1 had a low rate of photosynthesis because 0.5 grams of baking soda did not provide a sufficient amount of CO2.Cup 3 had the same rate of photosynthesis as Cup 1 because they had the same ratio of disks floating to wattage of light.Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Answer:
D. Cup 4 had the lowest rate of photosynthesis because it had the least CO2.
Explanation:
Carbondioxide gas is the main reactant for the process of photosynthesis which decides the production of food in the leaves. If plants has high amount of carbondioxide gas and water so in the presence of sunlight it produces more food in the leaves in the form of glucose so we can conclude that the lowest rate of photosynthesis occurs due to presence of least concentration of carbondioxide gas in the cup 4.

The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25
0.75≤t≤3.25
The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.
What is quadratic equation?To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.
We can start by setting the equation for the rocket's distance above the ground level equal to 3200:
We can then solve this equation for t using the quadratic formula
[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]
Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

A certain mutation in the gene for hemoglobin results in the red blood cells becoming sticky,
rigid, and irregularly shaped. These irregularly shaped red blood cells block the flow of blood
throughout the body. A single base mutation is responsible for these irregularly shaped blood cells.
Which of these mutations most likely results in the mutated hemoglobin gene?
F. Insertion
G. Deletion
H. Duplication
J. Substitution
Answer:J
Explanation:Substitution
Mutation in genes can result in different types of abnormalities. In gene related to hemoglobin makes RBCs sticky, irregular shaped, this is because of substitution.
What is substitution?Mutation is a type of replication error during formation of new DNA.
In substitution mutation, incorrect nucleotide is placed at incorrect position during DNA replication, a point mutation occur in which a single nucleotide is substituted.
It actually does not add or remove any nucleotide from the sequence, just it substitute it.
In gene related to hemoglobin, the amino acid glutamic acid gets replaced with the valine amino acid at position 6 in beta-globin, which results in sticky, irregularly shaped red blood cells.
Thus the correct option is J.

Question:
Use the following dichotomous key to identify an irregular blue flower with five petals and a fruit that is a ripened flower ovary or follicle.
Dichotomous Key of Ranunculaceae
#1.
a. Fruit is a group of alkenes.............................. go to step 2
b. Fruit is a group of follicles..............................go to step 4
#2.
a. Petals are not present.....................................go to step 3
b. Petals are present............................................Ranunculus
#3.
a. The flower has 4 sepals.................................. Clematis
b. The flower has 5 sepals................................... Anemone
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
The flower is a: A. Anemone B. Clematis C. Delphinium D. Ranunculus
Answer:
The species belongs to Delphinium genera.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
- carefully observe your organism,
- know some technical terms or have a biological dictionary, and
- follow the descriptions.
The dichotomous key is going to lead you to the answer.
In the example, we have a plant species with irregular blue flowers and five petals. The fruits are a ripened flower ovary or follicles.
Irregular flower: Term that refers to asymmetrical flowers that only have one plane. Follicle: Term that refers to dry dehiscent fruits originated from a flower with only one carpel. When mature, they open by the ventral suture.So, let us begin, step by step. For each number, we are going to have two options (a and b). By knowing our organism, we need to decide which one is correct and follow indications.
#1.
a. Fruit is a group of alkenes.............................. go to step 2.
b. Fruit is a group of follicles..............................go to step 4.
We know that our fruit is a follicle. Option a is not correct (it is not a group of alkenes). Option b is the correct one. Knowing this, we must go to step four. ***Note: In the hypothetical case that the fruits were a group of alkenes, and option a was correct, we should go to step two, as indicated***.
#4.
a. The flowers are regular..................................... Aquilegia
b. The flowers are irregular................................... Delphinium
We know that our flower is an irregular one. So the correct option is b. This option leads us to Delphinium genera. Our species belongs to this taxonomic group. ***Note: In the hypothetical case that the fruit was actually a regular flower, and option a was correct, our species would belong to Aquilegia genera***

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

Answer:
Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other
Explanation:
Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.
What is classification?Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.
Patterns are regular and intelligible forms , sequences, or structure that found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.
For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.
Thus, it is clear from above explanation, the ways to use patterns of classification in science.
