follicle-stimulating hormone is a pituitary hormone that acts on the follicle cells of the ovary to trigger the synthesis of cyc

lic AMP, which stimulates various metabolic changes. FSH normally has no effect on cardiac muscle cells. However, when ovarian follicle cells and cardiac muscle cells are grown together in mixed culture, a number of the cardiac muscle cells are seen to contract following addition of FSH to the medium. How might this observation be explained?

Answer:

Cells grown in culture tend to adhere to each other, through adhesins, so they are able to communicate with each other. They form gap junctions that allow the cytoplasm of the cells to exchange some molecules such as cyclic-AMP associated molecules in this case.

Therefore even though the FSH binds to the receptors on the ovarian follicle cells only (since these are the cells that bear the receptors for the hormone on their surface), the pathway and associated molecules for secondary messengers can diffuse across the across the gap junction into other cells, including those of the cardiac cells, hence inducing some contraction in these cells, as they respond to the secondary messengers.

Which feature of insects has promoted their diversification and evolutionary success?
Luda [366]

Insects has repeated modular segment that develop independently of each other promoted their diversification and evolutionary success. They are able to evolve appendage that are specialized for diverse functions.

Hypotheses propose that insect diversity either result form low extinction rates and resilience to mass extinctions and acquisition of key innovation that allowed them to radiate into newly formed niches.

There exoskeleton characteristics are commonly responsible for the diversification of insects on land. These insects are the amazing diversity in the surrounding , it believed that insects are so successful because they  have protective shell /exoskeleton , they have small in size and they can fly.

What is the difference between the leading and lagging strands
mezya [45]
In DNA there are two types of strands, 5'/5 prime, which is the strand, aka the leading strand. 
There is also the 3' strand which is the lagging strand. 
The difference between these two is the the leading strand is discontinous during replication, they must create ozaki fragments.
The other lagging strand can just have the whole strand replicated at the same time
