Which of the following is not a possible effect of increasing carbon dioxide levels in the atmosphere?
a. increase in water contamination and floods
b. ocean acidification
c. cutting down forests
d. reduction of cold-related deaths

Option (C)

Explanation:

Carbon dioxide (CO₂) is one of the green house gases that can cause great impact on the earth. A small increase in the amount of CO₂ can lead to the increase in the global temperature of the earth. The effect of increasing CO₂ content in the atmosphere can cause the sea level to rise by melting the ice that are at the polar regions. It can also lead to flood and water will be contaminated. The CO₂ available in the atmosphere will mix up with the ocean thereby reducing the pH level and causing ocean acidification.

Whereas, Cutting down of trees (forests) refers to the deforestation process and it is an anthropogenic activity that leads to the increasing amount of CO₂ in the atmosphere.

Thus, deforestation process is a cause for the increasing global CO₂ content, and is not an effect of it.

Hence, the correct answer is option (C).

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
