Answer: Homeostasis is a resistance to change.
Explanation: There are many other examples of homeostasis in biology, like the pH of blood and the concentration of ATP in a cell.
D. Protein
Carbohydrates are made from three elements known as Carbon, water, and oxygen.
DNA is made up of phosphate sugar groups for the helix and nitrogenous bases for the inside.l
Lipids also are only made form carbon, water, and oxygen but in a different ratio.
Answer:
D. The presence of aquaporins (proteins that form water channels in the membrane) should speed up the process of osmosis.
Explanation:
Water moves in the cells through osmosis which means water moves from its higher concentration to lower concentration. In many animals and plants, water channels are also present which is called aquaporins which allow the water to move through it in and out of cell more quickly.
The rate of diffusion by channel proteins is higher than simple diffusion therefore the aquaporins speed up the process of osmosis. No ATP is required to transport the water through aquaporin channel proteins.
Organisms from all six kingdoms have DNA but some are not enclosed inside the nucleus but scattered in the cytoplasm.Only eukaryotes have nuclei where DNA strands are enclosed.
