How do cells get rid of the largest waste materials?A. by diffusion
B. by transport proteins
C. by osmosis
D. by exocytosis

Answers

Answer 1
Answer:

Answer:

Cells use both diffusion and osmosis to get rid of their wastes. Cells can bias the movement of waste molecules out of and away from themselves. One way is to temporarily convert the waste product into a different molecule that will not diffuse backwards.

What activity is accomplished using the genetic code?cells make proteins.
RNA molecules are copied before mitosis begins.
mRNA molecules are transcribed to form tRNA.
polypeptides are made into mRNA.

Answers

(A) Cells make proteins
Proteins are composed of amino acids. Proteins are made in a process called translation, in which the cell commands.
(B) RNA molecules copied before mitosis begins
DNA molecules are copied before mitosis, not RNA.
(C) mRNA molecules are transcribed to form tRNA
DNA is used as template to form both mRNA and tRNA in a process called transcription.
(D) polypeptides are made into mRNA
mRNA is the template used to make polypeptides in a process called translation.

Therefore, A is the right answer.

Which adaptation might be found in the greater yellow-headed vulture, but not in the harpy eagle?a. a acute sense of smell
b. a powerful, hooked bill
c. close-set eyes to judge distances
d. short wingspan for maneuverability

Answers

The correct answer is a. acute sense of smell. The greater-yellow headed vulture has developed this particular adaptation as a result of its diet, which consists of the dead corpses of forest mammals. Unlike the harpy eagle, which hunts for live prey, the vulture feeds upon animals which are no longer moving so this highly developed sense of smell is necessary for survival.

Answer:

A: acute sense of smell

Which of the following is a contributing reason behind emerging disease? a. The lack of evolution in hostsB. The overuse of antibioticsC. The absence of migration or travel in organismsD. The lack of evolution in pathogens

Answers

The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing. Since it's difficult to find new types and the trials last long, new diseases are emerging faster than we can create medicine for them.

Fill in the blank: When you paddle a boat in the water. the force of your paddle will push the water which will apply an equal force back on you. There is very little resistance to this motion because there is a limited _______ force between the canoe and the surface of the water due to the smooth surface​

Answers

Answer:

frictional

Explanation:

This scenario follows Newton's third law of motion which alludes to the fact that for every force or action exerted by a person on a body there is an equal and opposite reaction exerted back.

Because there is a limited frictional force (a force exerted by an object when an object moves across it) between

  • the canoe and
  • water surface (the opposite force/reaction)

Here, the paddle helps the boatman apply a force on the water, resulting in the opposite amount of force been sent back; pushing the boat forward.
