It depends on the situations. In the first situation, a Yy gene crosses with a Yy gene. 3 out of 4 of the outcomes have a capital Y in them, meaning that they have a dominant yellow allele. The bottom-right box has two lower-case y's, so it will be green. In the second situation, a YY gene crosses with a Yy gene. Here, all 4 out of 4 of the outcomes have at least one capital Y, so they will all be yellow. Hope that helps!

Because in order to be yellow the only 2 alleles you can have are the 2

Which reactant of photosynthesis is also involved in climate change?

choli [55]

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
