The gene Brachyury promotes development of the notochord and the vertebrae in vertebrate animals. Among the rodents, most species have a long tail, but capybaras have a very short tail. What is the most likely difference you might expect to see for the Brachyury gene in capybaras compared to long-tailed rodents

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
