Essential nutrients move through a cell membrane by both passive transport and active transport. Which of the following correctl

y describes the transport of materials across a cell membrane?
Biology
1 answer:
Inessa [10]3 years ago

Answer: A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.

Explanation:

Sometimes cells require nutrients such as sodium and potassium to be transported from an area where they are in low concentration to an area where they are in high concentration.

This goes against the concentration gradient where substances are transported from an area of high concentration to one with low concentration as is the case in processes such as osmosis.

This process is called Active transport and describes the use of chemical energy to move nutrients from areas of low concentration to areas of high concentration.

zavuch27 [327]
Depednign on what the cell is trying to transport there could be a variety of ways for the cell to transfer materials.
If the item is small and np then it can go through the lipid bilayer.



Simple diffusion and facilitated diffusion are passive transport meaning the cell does not need energy to transfer the membrane

and active diffision means they need to spend energy.

you need transmembrane protiens to move things inside the cell

Students use a compound light microscope to view unicellular organisms collected from pond
Maksim231197 [3]

The statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope is as follows:

  • Compound light microscopes have higher magnification.

Thus, the correct option for this question is C.

<h3>What is a Microscope?</h3>

A microscope may be defined as a type of laboratory instrument that is significantly utilized to examine or observe objects that are too small to be visualized by the unaided eye.

Dissecting microscopes possess a lower magnification power as compared to compound light microscopes. Due to this, dissecting microscopes are used to visualize larger objects like tissues. Compound light microscopes use more than one glass lens. These types of microscopes are used to examine living cells.

Therefore, a compound light microscope has higher magnification is a statement that describes the utilization of a compound light microscope is better to view the structures of these organisms than a dissecting microscope. Thus, the correct option for this question is C.
