Answer:
Because of the difference in surface area to volume ratio
Explanation:
Surface are to volume ratio is the area of an object that is exposed to the external environment (surface area), compared to the amount within an object (volume).
Therefore an elephant has a lower surface area to volume ratio than a mouse.
The smaller an object is the greater its surface area to volume ratio.
Small animals have much more surface area per mass than large animals. With so much surface area, they lose heat very quickly. So, a mouse, with a lot of surface area per mass, must spend a lot more energy to stay warm than a large animal.
In stem cell transplants, stem cells replace cells damaged by chemotherapy or disease or serve as a way for the donor's immune system to fight some types of cancer and blood-related diseases
The answer is true, Sponges can regenerate the entire organism from just a conglomeration of their cells. They can be cut up or mashed, and as long as they have two special cells called collencytes, which produce the gelatinous matrix in the sponge, and archeocytes, which produce all the other cells in the spongeâ??s body, the sponge will reform into the sponge it once was. Although, it will look different. Hope it helps!
