It is an independent variable. Thus option A is correct.
What are the key difference between Independent and dependent Variable ?
The variable whose values are changed by researcher to get desired outcome is called an independent variable.
The variable, by changing its values to reciprocate change in the values of the independent variable is called the dependent variable.
The independent variable is act as the experiment controller whereas, the dependent variable act as experiment measure.
An independent variable is a cause whereas the dependent variable is an effect of that cause.
we can say in a linear regression, ‘y’ denotes dependent variable while ‘x’ denotes independent variable.
An independent variable does not rely on anything, while the dependent shows the effect, due to changes in independent variable.
Thus option A is correct.

Which provides long-term energy storage?
glycogen, because it is a polysaccharide
glucagon, because it is a complex protein
glucose, because it is a monosaccharide
O cellulose, because it is a complex carbohydrate
Answer:
glycogen
Explanation:
because it is a polysaccharide
Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.
What is Glycogen?Glycogen is defined as a multi-branched polysaccharide of glucose that serves as energy storage in animals, fungi and bacteria which is the main storage form of glucose in the human body.
The body mainly uses glycogen stores in the liver to help regulate blood glucose which is sugar levels where the body normally regulates blood glucose mainly with the hormones glucagon and insulin. When the blood sugar level becomes too low, which is called hypoglycemia, the pancreas releases more glucagon.
Thus, Glycogen because it is a polysaccharide which provides long-term energy storage. So, the correct option is A.

Give the two ways nitrogen can be fixated so plants can use it to grow.
[tex]\huge\mathfrak\red {Answer:}[/tex]
FixationNitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
Biologically:Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
Through lightning:Lightning converts atmospheric nitrogen into ammonia and nitrate (NO3) that enter soil with rainfall.

Using complete sentences, compare and contrast the terms living and biotic. In your response, illustrate using examples and appropriate compare-and-contrast vocabulary
Both living things and biotic factors can be alive.
Unlike living things, biotic things may not be alive; they may have once lived or came from something living.
I included an example of something both living and biotic, such as flowers.
I included an example of something biotic, but not living, such as paper.
I used compare-and-contrast vocabulary.
Explanation:
As you all know that living is a synonym for biotic, as both discuss the measures of life. It significantly includes plants, animals, humans, predators, etc.
What is biotic?Biotic may be defined as something that is closely related to living organisms or something that is directly derived through the action of living organisms.
As compared to living, biotics may not always be alive, but it talks for a long period. Biotic is something that has once lived or emanated from something living.
Examples like plants, animals including humans are categorized under the category of living, while products such as rubber, latex, cow dung, paper, etc are biotic products that are not living.

What is the variable that affects enzyme function in the example of phosphofructokinase-1?
Answer:
This question is incomplete
Explanation:
The question is incomplete because the example referred to was not stated. However, phosphofructokinase-1 is a key enzyme in glycolysis; it converts/phosphorylates fructose-6-phosphate to fructose-1,6-bisphosphate in the presence of ATP to release ADP. It is a regulatory enzyme in this pathway (glycolysis) because it's function can be affected by an increased ATP to ADP ratio which inhibits the enzyme (phosphofructokinase-1) and indeed glycosis itself.

Structure has no apparent function in a species, but is fully functional in the species' ancestors.
a) true
b) false
Answer:
The correct answer would be - True.
Explanation:
In several organisms have structures, has no apparent role in the particular species and are residual parts from a past ancestor, but these structures were fully functional in the ancestors of the species. These structures are called vestigial structures or organs.
The example of such structures are, wings of the flightless birds, appendix of human and many other, all these structures has no function in the body of the individuals of the particular species but is fully functional in ancestors.
Thus, the correct answer is - true.
