PLEASE HELP!! 50 POINTS + BRAINLIEST What did Mendel's cross-pollination of pea plants prove? Different offspring of the same parents inherit identical characteristics. Hereditary factors do not combine but are passed on in the same form they were inherited. Factors carry the code for proteins in segments of RNA. Dominant traits are always expressed and recessive traits are always hidden.

What are the types of mutations, and how does each alter the encoded protein? college level answer

Use the phylogenetic tree to the right to determine which statement below is true. organisms a and f are not related. organism e is more closely related to organism b than organism f. organisms c and d are more closely related than organisms a and b. phylogenetic trees

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.
