Infants are born with soft spots in their skull made out of cartilage. What do you think happens to soft spots over time?

In general, are there any major differences that you can see? explain

In a leaf, dermal tissue a) stores food b) stores carbon dioxide c) releases oxygen into the air d) transports water from the roots

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
