Which process requires the use of membrane proteins?A) pinocytosis

B) diffusion

C) osmosis

D) facilitated diffusion

Answers

Answer 1
Answer:
  • When the process required the use of membrane proteins are:

                   Facilitated diffusion

  • According to the cells, when some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly.
  • Although Facilitated diffusion is that the passive movement of molecules across the cell wall via the help of a membrane protein.
  • When it's utilized by molecules that are unable to freely cross the phospholipid bilayer
  • Thus, while others must suffer membrane proteins during a process called facilitated diffusion.

What is a cyclical disturbance?a. a disturbance that removes organisms
b. a disturbance that repeats over and over
c. a disturbance that kills keystone species
d.a disturbance that destroys soil

Answers

Answer:

The correct answer is option B.

Explanation:

A disturbance is a short term change in environmental conditions that causes a noticeable alteration in an ecosystem. If this change repeats itself over and over it is characterized as Cyclic disturbance.

This change or disturbance takes place because of several disturbance forces and in the absence of these forces ecosystem tends to return to conditions as it was pre-disturbance conditions.

Thus, the correct answer is option B.

A disturbance that repeats over and over

What types of traits can show genetic variation within a species?​

Answers

Answer:

Types of variation in genetics

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring)

other answer

There are three sources of genetic variation: mutation, gene flow, and sexual reproduction. A mutation is simply a change in the DNA. Mutations themselves are not very common and are usually harmful to a population. Because of this, mutations are usually selected against through evolutionary processes

Which statement about forces is true? A. Forces are defined by strength but not direction. B. Forces are defined by direction but not strength. C. Forces are defined by both strength and direction. D. Forces act only on objects that are in contact.

Answers

Answer: Option (C) is the correct answer.

Explanation:

A force is defined as the strength applied on an object to displace it from its initial position.

This, force applied to move the object is known as work.

Mathematically,              W = F × d

where         W = work done

                   F = force

                   d = displacement or distance moved

Thus, we can conclude that the statement forces are defined by both strength and direction, is true about forces.

Answer:

C

Explanation:

The direction and strength affect the force
