Long Answer: The diploid number is 46n and haploid number is 23, the diploid is double if that helps you remember, but a haploid number is an egg or sperm cell so that when those cells meet for reproduction it would then be 46.
Short answer: haploid- 23...diploid-46
active transport, because glucose is very large molecule.
Answer;
2) the rate at which changes occur in a type of molecule
Explanation;
The molecular clock is figurative term for a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.
Scientists can use relaxed-clock methods to deal with variation in the rate of the molecular clock. By measuring the patterns of evolutionary rate variation among organisms, they can also gain valuable insight into the biological processes that determine how quickly the molecular clock ticks.
The best option would be the letter A. They supply freshwater to support life on Earth.
Freshwater is the ultimate source of water in the terrestrial biome. It is not only important in the terrestrial biome but also in the aquatic ecosystem as it helps in transporting nutrients (ex. river is connected to the ocean).
