The answers that I selected were wrong so I’m confused. What are the answers

C, and C

Explanation: So, the nucleus performs a number of different tasks from storing information, to making ribosomes, the synthesizers of proteins, so your answer is correct, but the nucleus also creates nucleic acids, which are the building blocks of DNA and store that information in their makeup. Proteins are actually made outside of the cell, by ribosomes. This is confusing because ribosomes are actually made inside the nucleus, but mature ribosomes only function outside of the cell. This is the only place they perform protein synthesis.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
