Answer:

B. Carbon dioxide

Explanation:

First of all, let’s write out the photosynthesis equation to identify the products and reactants.

6CO2 + 6H2O + energy —> C6H12O6 + 6H2O

In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.

In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.

Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.

We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.

Therefore, the best answer choice is B. Carbon dioxide

The decline of mpf activity at the end of mitosis is due to

raketka [301]

Answer:

Please read explanation section.

Explanation:

MPF is a protein kinase. It catalyzes the transfer of a phosphate group from ATP to target proteins.

One of the pathways which are stimulated by the MPF is an enzyme that destroys cyclin. This means it stimulates the cyclin pathway. As mitosis gets initiated, the enzyme that breaks down cyclin becomes activated, and levels of cyclin start to be dropping down. The declining levels of cyclin lead to reduced levels of the MPF.

The human body is composed of cells, organs, organ systems, and tissues. How are these organized?

Vanyuwa [196]

Cells make up the tissues which combine to form the organs and then different organ systems make up the organism
so it's cells-tissues-organs-organ system-organism

If female deer mates with male deer that have large antlers 2 we are witnessing_____ selection.

valkas [14]

The answer would be natural selection.

The female deer might consider the large antlers of the male deer to show of certain genetic qualities that have a higher probability of reproduction, as well as a higher social status among deers.

This means that if she picks him as her mate during this season, their offspring will have a better chance of survival compared to her picking another deer with smaller antlers.

This is called natural selection because she will pick the deer that is most adapted to that environment. Thus their offspring can be ensured to have the highest possible probability to survive.
