2. in an experiment, the efficiency of oxygen exchange across the plasma
membrane is being assessed in four artificial red blood cells. the table
above lists some properties of those artificial cells. other conditions being
equal, which artificial cell is predicted to be the most efficient in exchanging
oxygen with the environment by diffusion?
a. the cuboidal cell
b. the tetrahedral cell
c. the cylindrical cell
d. the spherical cell

nucleus

would be most reasonable answer tbh

well for one plants are always the producer, so a is the answer. a wolf is more of the consumer(predator) and the deer is the prey so i know those two are out of the question. also mushrooms are fungi/fungus so a is the producer.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

explanation:

the answer is
