Answer:
The answer is A).
Explanation:
Based off <u>https://dlc.dcccd.edu/biology1-3/organic-molecules</u>, "In most organic molecules, a linked chain of carbon atoms forms a backbone to which other atoms attach. The unique number and arrangement of bonds between carbon atoms creates a structurally diverse set of organic molecules in nature."

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:
The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.
In which squares should the phrase “Green pods” appear?
1.A and D 2.B and E 3.A,C and D 4.A,B,C,D and E
Answer:
3.A,C and D
Explanation:
As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.
As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.
Hello There!

Answer:
Difference in their beak size, colour of their feather and body size.
Explanation:
The genetic variation that occurs in the three different species of bird is the difference in their beak size, colour of their feather and body size. The difference of beak size occurs due to difference in their food selection that is available to the birds. Some birds of the population feed on small food particles having small beak size whereas other have large beak size due to preference of large food materials. Some birds have colour like their surrounding that helps them to hide from their predators. Some birds specie have large body size due to availability of more food or due to genetics.
Answer: Feed-back inhibition
Explanation:
When the final product of a biochemical pathway signal the inactivation of the starting materials of the pathway, feed-back inhibition is said to have occurred.
In this case, the amino acid, isoleucine signal the inactivation of its starting material. Thus, it is an example of feed-back inhibition
