Why might farmers and herders have selectively bred their animals and plants?

Farmers and herders can derive a surplus of animals and plants with desireable traits. (ex: larger crops, bigger animals, sweeter fruits etc.)

Explanation:

By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock. Same thing goes for plants. Farmers can selectively breed them so they can become more favorable for their consumers.

Hope that helps!

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
