Please help! Will pick brainist! Manatees have toenails on their feet. The toenails are left over when the ancestors of manatees walked on land. They have no function today. Manatee toenails are examples of ...
A. comparative anatomy.
B. DNA.
C. fossil record
D. vestigial structures.

Which statements correspond to cellular respiration? co2 diffuses passively into the cell. co2 diffuses passively out of the cell. co2 must be pumped out of the cell. o2 diffuses passively when produced inside the cell. o2 diffuses passively when converted to co2. o2 is pumped in and forces co2 out.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f

Part e - sequence of metabolic processes each of the different cellular metabolic pathways occurs in a specific order. consider aerobic cellular metabolism from the beginning to end. what is the sequential order of the metabolic processes that starts with glucose and results in the production of carbon dioxide, water, and atp? put the following in the correct sequential order. rank from earliest to latest. to rank items as equivalent, overlap them. view available hint(s) acetyl coaglycolysiscitric acid cycle pyruvate finishstartstart background image electron transport chain background image finish background image submit cellular metabolism is often expressed as an equation. this equation puts into perspective, on a general scale, the substances needed to start cellular metabolism and the products that come out of it. the equation represents the overall product yield after every step of cellular metabolism is complete (i.e., glycolysis through the electron transport system). in this part of the tutorial you task will be to put together the equation that represents cellular metabolism. you will also learn the products that result from each metabolic pathway and the role that some these products play in the production of atp.
