Symbiotic relationships between plant roots and fungi are called
a. root nodules.
b. tendrils.
c. mycorrhizae.
d. protists. user: the xylem in the vein of the leaf
a. takes carbohydrates produced in photosynthesis to other cells in the plant.
b. takes carbon dioxide and water made in photosynthesis to other cells in the plant.
c. takes water to the mesophyll cells for use in photosynthesis.
d. takes carbohydrates to the mesophyll cells for use in photosynthesis.

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).

Glucose is a form of sugar found in the blood cells use glucose as a source of energy, but too much or too little can cause serious health issues so, the body uses the hormone insulin to regulate glucose n the blood insulin maintain glucose levels in the blood if blood glucose lovels got very high, what would you expect to see happen to insulin levels?

What are antigens and antibodies? how are they involved in the body’s response to incompatible blood?
