Answer:

C

Explanation:

I would say it is C.

Each cell has 23 chromosome (46 in total). 23 is from our mother, 23 from our father. So this would mean the chromosomes are not genetically identical, hence we have variation.

Hope this helps!

The appropriate response is the second one. Parallel fibers emerge from granule cells in the cerebellar cortex. Granule cells are little and exceptionally various. They are thought to make up the same number of as half of the neurons in the cerebrum. Granule cells have axons which ascend and afterward fan out into parallel filaments. These filaments meet the Purkinje cell dendrites.

the data collected over the years clearly confirm depletion of ozone in the stratosphere. what do scientists still need to learn
Lisa [10]

<span>Ozone is simply a molecule consisting of 3 oxygen atoms, which reacts strongly with other molecules. Ozone is created in the stratosphere when high energy uv radiation causes on O2 molecule to split. The free oxygen atoms collide and react with other O2 molecules to form O3.</span>

Production is highest where the solar uv is the greatest eg near the tropics, but once created, the ozone is then circulated towards the poles by the atmosphere. The amount of ozone in the stratosphere can vary with location, season and even day to day climatic conditions.

<span>The process of ozone creation is what makes the O3 in the atmosphere very effective at shielding the Earth from harmful uv radiation, which can cause many biological problems, such as skin cancer. However, due to its high reactivity, the uv found in the tropospher at ground level can aslo be dangerous as a toxic pollutant which is harmful to plants and lung tissue, and is a major cause of smog.</span>
