Dna replication occurs prior to meiosis and

Hello,

The answer is option A "mitosis".

Reason:

Mitosis one of the stages of a cell where the cells are separated into two chromosomes therefore putting them into a nucleus. Its not option B because cytokinesis is another part and divides one cell into two daughter cells (which means this is involved of the sex of the child). Its also not D because transcription is involved in gene expression.

If you need anymore help feel free to ask me!

Hope this helps!

Explanation:

Okay so, The Energy pyramid is the pyramid and order which energy is used and recycled. At the top of the pyramid you have the Animals at the top of the food chain such as humans, lions, ect. At the bottom you'll have, of course, things at the bottom of the food chain such as grass. How it works is the grass turns the sunlight into energy, which the grass is then consumed by an insect such as a grasshopper. The energy that was given to the grass is now in the insect. The insect gets consumed by one of its hundreds of predators, which is then consumed by the superiors of the food chain such as ourselves. Then of course we die then that's where the decomposers come in. Just munching on your remains and converts into the energy for mushroom. Then it starts all over again.
