Capillaries are one cell thick and so this makes them very thin. capillaries are also arranged in networks known as capillary beds, and thus multiple capillaries are spread over a large area.
Answer: DNA provides a set of chemical instructions to specific genes that the gene uses to make proteins in order to determine traits.
Explanation: Genes provide instructions that are used to determine the sequence of amino acids needed to make up a protein.
This membrane mimics the plasma membrane that is around animal cells. In order to explore how water moves in and out of a cell, one cell was weighed and then submerged in hypertonic solution. The other egg was weighted and submerged in hypotonic solution. It was predicted that the egg submerged in hypertonic solution would decrease in mass. It was predicted that the egg submerged in hypotonic solution would increase in mass.
Explanation:
The outermost covering of an animal cell is the plasma membrane. It is a selectively permeable membrane that allows only selective molecules to pass through it.
A solution having higher concentration of solute than the cell cytoplasm is called a hypertonic solution.
A solution having lower concentration of solute than the cell cytoplasm is called the hypotonic solution.
The movement of water molecules from the region of its higher concentration to the region of its lower concentration through a semipermeable membrane is called osmosis.
A cell placed in hypertonic solution will undergo exosmosis so it will lose water and its mass will decrease.
A cell placed in hypotonic solution will undergo endosmosis of water so it will gain water and its mass will increase.
Answer:
The protein is known as Uncoupling protein 1 (UCP1) that is present in inner mitochondrial membrane of brown adipose cells of mammals and other organisms undergoing hibernation.
Function:
- The protein allows the organisms to produce metabolic heat that helps in the organism’s regulation of body temperature.
- This protein can also serve as a source of carbon for the production of carbohydrates when organism faces the period of prolonged fasting and thus help the organism to survive.
- The protein also helps in the movement of protons into the mitochondrial matrix that ultimately activate the electron transport chain and releases more and more heat for body’s maintenance.
Hope it helps!
The answer is orange because the way that he said the problem out.
