The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails
Answers
Answer:
The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.
Explanation:
Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability. Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.
In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.
The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.
The other options are not correct because:
a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.
b. Carbohydrates for cell recognition do not determine membrane permeability.
c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.

4. for curing heart disease by regenerating damaged heart tissue
I HEARD THAT 4 IS NOT CORRECT SO PICK THE CORRECT ONE THA ISNT FOUR. ITS FROM EDGE2020
Answers
Answer:
1. For generating healthy cells to form replacement organs like brains
Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.
What is stem cell?Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.
Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.
Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.
This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.
Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.
Thus, the correct option is 4.

Group of answer choices The bacteria would grow by itself outside the person. The virus would have DNA. The bacteria would make another person sick. The virus would have proteins.
Answers
Answer:
The bacteria would grow by itself outside the person
Explanation:
The bacteria would grow by itself outside the person. - this is correct. Bacteria are independent organisms that do not need other cells to replicate. However, viruses require the cell's machinery to divide and cannot survive independently
The virus would have DNA. - Both bacteria and viruses have DNA (or the virus might have RNA)
The bacteria would make another person sick. - Both viruses and bacteria could make another person sick
The virus would have proteins - Both viruses and bacteria have proteins
