The answer is C
Completing multiple trials during an experiment
The rest of the options are possibilities of how you can "mess up" and experiment, but if you run multiple trials doing everything right, for example, making sure all variables are controlled, using the right equipment, and making sure you cover all possible variables. If you make sure you do multiple trials and you do them right, you get successful results.
So the answer is C
I hope this was helpful :)
Goodluck!!
High levels of cortisol would normally provide negative feedback to the D)the anterior pituitary and the hypothalamus.
ACTH secretion stimulates the discharge of glucocorticoids (cortisol), mineralocorticoids (aldosterone), and androgen from the adrenal cortex.
Corticotropin-liberating hormone (CRH) is launched from the hypothalamus, which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH). ACTH then acts on its target organ, the adrenal cortex.
Cortisol increases blood sugar by way of releasing stored glucose, at the same time as insulin lowers blood sugar. Having chronically high cortisol stages can result in continual high blood sugar (hyperglycemia). this can purpose type 2 diabetes.

The given statement is False. Hence, the correct choice is F.
The activity of the plants and the animals are influenced by the abiotic factors present in their environment. The change in the abiotic factors outside the body such as the temperature, air and the presence of the water molecules provoke responses in the body of the organism. For example, the winters (low temperature) causes the loss of the leaves in the deciduous trees and the increase in the temperature causes more sweating in our body.
The reason for the change in the hands of the chimpanzee include:
- Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
- Mutations in chimpanzee DNA ( Represents a reason for the change)
- Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
- Sexual reproduction ( Doesn't represents a reason for the change)
- Differences in enhancer sequences( Represents a reason for the change).
<h3>What is mutation?</h3>
Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:
- When there is spontaneous break down of deoxyribonucleic acid (DNA).
- Change in a single nucleotide of the DNA.
- when there is additions or deletions of nucleotide in a DNA strand.
A change can be noticed in an animal such as Chimpanzee when the following occurs:
Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.
Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

The proteins are called Histone proteins. Chromosomal DNA is packaged such that the strands of DNA are wound around histone proteins and fold into complex ways to form chromosomes. The histone proteins are positively charged proteins that strongly adhere to negatively charged DNA and form complexes called nucleosomes. Each nucleosome is composed of double-helical DNA wrapped.
