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

The blisters are a result of the accumulation of the fluid between the epidermis (outer layer of the skin) and the layers below it. So, for blisters to occur, at least damage to two layers of skin is necessary.

In first degree burn, due to the damage to epidermis only, the redness occur and the blisters does not occur.
