Answer:

True

Explanation:

This is essentially natural selection. If there is a population of giraffes and half of them have long necks and the other half have short necks, the ones with long necks will be more likely to survive because they will be able to reach more leaves on tall trees. This means the ones with short necks will be less likely to survive, so when the long neck giraffes reproduce, they will pass on the gene for a long neck to their offspring. Over time, there will be more and more long neck giraffes and fewer short neck ones.

This is just a silly example but it is actually have animals have evolved over thousands of years lol

How does hail form? what factors govern the ultimate size of hailstones?
aivan3 [116]

Hail is formed when the water droplets freeze together in the cold upper region of the thundercloud. These lumps of ice are called hailstones. Most hailstones are between 5 mm and 15 cm in diameter and can be round or jagged. Hail stones are not frozen raindrops.

                        Factors that govern the ultimate size of hailstones are hail has strong storm clouds, especially strong heat, high liquid water content, large vertical range, large water droplets, and many cloud layers are formed by clouds below 0 ° C (32 ° F). This type of intense heat may also indicate the presence of a tornado.

Describe what happens to collagen when it's heated
vova2212 [387]
Well collagen is a globular protein with a tertiary structure. when you heat it up the energy will break the bonds that form between the chains of amino acids such as hydrogen and ionic bonds which will cause the shape of the collagen molecule to change and become less ridged and stable and more fluid.

hope that helps
