Mitosis is a type of cell division that produces cells that are identical to the parent cell. Meiosis is a different type of cell division that produces cells that carry half the genetic material of the parent cell. Based on the information provided, how do the purposes of mitosis and meiosis differ?
A.
Mitosis produces cells used for growth and repair, while meiosis produces cells used for reproduction.
B.
Mitosis is only used by single-celled organisms, while meiosis is only used by multicellular organisms.
C.
Mitosis creates cells used for reproduction, while meiosis produces cells used for growth and repair.
D.
Mitosis is only used by multicellular organisms, while meiosis is only used by single-celled organisms.

Two true-breeding pea plants were crossed. one parent is round, terminal, violet, constricted, while the other expresses the respective contrasting phenotypes of wrinkled, axial, white, full. the four pairs of contrasting traits are controlled by four genes, each located on a separate chromosome. in the f1 only round, axial, violet, and full were expressed. in the f2, all possible combinations of these traits were expressed in ratios consistent with mendelian inheritance. (a) what conclusion about the inheritance of the traits can be drawn based on the f1 results? (b) in the f2 results, which phenotype appeared most frequently? what mathematical expression predicts the probability of occurrence of this phenotype? (c) which f2 phenotype is expected to occur least frequently? what mathematical expression predicts this probability? (d) in the f2 generation, how often is either of the p1 phenotypes likely to occur? express your answer as a fraction (example: 3/16).

Which statement describes a way in which the digestive and excretory systems work together? a. the nephrons absorb nutrients from food going to the large intestine. b. the excretory system balances blood gases in the small intestine. c. the intestinal villi filter blood and send wastes to the bladder. d. the excretory system balances the salts and water obtained from digested food

Will ! a cell containing a 3% sucrose solution is placed into a beaker containing a 7% sucrose solution. assume the cell’s membrane is permeable to water, but not permeable to the sucrose. where will the water diffuse? explain.
