Question

question 28 1 pts diffusion can be defined as the net movement of molecules from a region of higher concentration to a region of lower concentration. the movement of water across a membrane that permits free movement of water but not solutes. an excretory process. a process in which cells engulf particles. question 29 1 pts meiosis is called
eduction division\ because the cells reduce in size. the cells reduce in number. the number of chromosomes is reduced by half. the sizes of the chromosomes are reduced. question 30 1 pts the result of meiosis is two daughter cells that are identical to the parent cell. two daughter cells that are haploid. four daughter cells that are identical to the parent cell. four daughter cells that are haploid.

Explanation:

• Question 28: Diffusion is the net movement of molecules from a region of higher concentration to a region of lower concentration. It is a passive - transport process. The movement of water across a membrane that permits free movement of water but not solutes is osmosis. An excretory process is related to waste - removal. The process in which cells engulf particles is phagocytosis.
• Question 29: Meiosis is called "reduction division" because the number of chromosomes is reduced by half. It starts with a diploid cell and results in haploid cells. The size and number of cells are not the reasons for the name "reduction division", and the size of chromosomes is not reduced in meiosis.
• Question 30: Meiosis results in four daughter cells that are haploid. Mitosis results in two daughter cells that are identical to the parent cell.

Answer:

Question 28: the net movement of molecules from a region of higher concentration to a region of lower concentration.
Question 29: the number of chromosomes is reduced by half.
Question 30: four daughter cells that are haploid.
