In the 6th pamphlet page, you will prepare for questions that visitors might ask about the movement from water to land. You should be familiar with the difficulties associated with it and the solutions that are evident in animals and/or plants.

What are the difficulties? An example is desiccation—plants that live in water do not have to worry about their embryos losing water.
What are the solutions? An example is that embryos in a seed don’t lose water.

a. decomposes use carbon from dead organisms as fuel for cellular respiration, returning carbon dioxide back into the atmosphere.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

lesson summarykaryotypes a genome is the full set of all the genetic information that an organism carries in its dna. chromosomes arebundles of dna and protein found in the nucleus of a eukaryotic cell.

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.
