Answer: Option E.

All are endoplasmic reticulum functions.

Explanation:

All are function of endoplasmic recticulum because

Endoplasmic recticulum is a membrane organelle that consists of two subunits, rough and smooth endoplasmic recticulum found in eukaryotes that formed flattened sacs within the cytoplasm of eukaryotic cells which syntyensises proteins, lipids and steroids, it metabolised carbohydrates by adding it to protein , help to control the concentration of calcium in the body,it detoxifies drugs, attached protein on receptor cells, assemble multimeric proteins e.t.c.

The endoplasmic recticulum comprises of two subunits which are rough and smooth endoplasmic recticulum. The major differences between rough and smooth endoplasmic recticulum is that smooth do not have RIBOSOMES and it produces lipids and rough have RIBOSOMES and produces proteins.

Hypothalamus; pituitary gland

Hypothalamix-pituitary-adrenal axis is a complex set of direct influences and feedback interactions among the three organ components which are the hypothamus, pituitary gland and adrenal gland. These organ and their interactions forms the HPA axis that controls the reaction to stress and regulates many body processes,including digestion, immune system mood and emotions

Which of the following is UNLIKELY to affect bone remodeling?

S_A_V [24]

Glucagon

This is a hormone that deals with blood sugar homeostasis. When blood sugar levels are low, glucagon is produced to convert the fats in the reserve back to glucose until normal levels are achieved.

Explanation:

Bone remodeling involves coordinations of osteoclasts and osteoblasts cells in the bone. The former breaks down bone tissue while the latter mineralizes bones. Calcium is the main ion in the body significant in mineralization of bone. Excess Ca2+ is stored in bone while low calcium levels in blood result in bone resorption.

Stress on a bone also causes increased mineralization to strengthen the bone against this stress. This is why astronauts when they go to space, due to less stress from low gravity, bone loses its mass. When they return back to earth, the bone readjusts to the increased stress from higher gravity by increased mineralization.

The hormone responsible for bone homeostasis is parathyroid hormone.

6. A scientist measures the circumference of acorns in a population of oak trees

melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.

Thus, option A is correct

8. In a directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.

Thus, option C is correct
