Answer: The answers seem correct.
1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.
2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.
3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.
Dominate animals hunt the smaller and weaker animals for survival.

Answer:
The cell of humans contains 46 chromosomes and is about to undergo cell division so two types of cells are formed. If the cell division occurs in somatic cells then mitosis occurs or if the cell division occurs in sex cells then meiosis occurs. In mitosis, two daughter cells are formed while in meiosis, four daughter cells are produced. In mitosis, each daughter cell has 46 chromosomes while in meiosis each daughter cell has 23 chromosomes.
