Microtubules, a structure of the cytoskeleton, are responsible for assuring that the two members of a homologous chromosome pair go to different daughter cells. During Anaphase I, the pair of homologous chromosome move to opposite sides of the cell, through a process called segregation. Microtubules emerging from a structure on the cell surface, called spindle, bind to each chromosome of the pair and ensure the separation of the pair.

C cells of the thyroid gland secrete calcitonin.

<h3>What does C cells of thyroid gland produce?</h3>
  • The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
  • It includes parafollicular cells, or C cells, which release calcitonin.
  • The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
  • When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
  • The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.

I think the answer is most likely be J.

The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.

1. Flowering plants and bees have influenced each other's evolution, providing an example of
Doss [256]

Answer:

1. coevolution

2. abiogenesis

3. Endosymbiont Theory

4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.

5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.

6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.

7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.

8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.
