I'm guessing changing gravity
Answer:
All colour except which is already present in the body.
Explanation:
The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.
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.
The difference between an artery and a vein is that arteries are larger, more muscular and more elastic than veins; they carry blood that is under pressure from having been pumped out of the heart; veins are under much less pressure, so they are not as strong
