The nontaxonomic term sea slug encompasses a wide variety of marine gastropods. One feature they share as adults is the lack of

a shell. We might think, therefore, that they represent defenseless morsels for predators. In fact, sea slugs have multiple defenses. Some sea slugs prey on sponges and concentrate sponge toxins in their tissues. Others feed on cnidarians, digesting everything except the nematocysts, which they then transfer to their own skins. Whereas the most brightly colored sea slugs are often highly toxic, others are nontoxic and mimic the coloration of the toxic species. Their colors are mostly derived from pigments in their prey. There are also sea slugs that use their coloration to blend into their environments.a.nematocystsb.an incurrent siphonc.a radulad.a mantle cavity

How did Mendel's<br> experiments provide evidence for the principle of<br> independent assortment?
Mrac [35]

Answer and Explanation

Mendel selected a group of dwarf plants and sel pollinated them by dusting mature pollen grains onto them. He then collected the resulting seeds and planted them and noticed these seeds germinated and grew into dwarf plants only.

He also selected tall plants and self-pollinated them. the resulting seeds he observed that they grew into a micture of tall and dwarf plants. He took the seeds of tall plants only and repeated the experiments for many generations until he obtained only tall plants.

He then crossed cross-pollinated purebreeds tall garden pea with pure breed variety. He planted the seeds and observed the offsprings were all tall plants. He crossed two of these tall offsprinf from the F1 and planted the resulting seeds. the second filial generation consisted of a mixture of tall and dwarf plants.

He counted these plants and noted that the ratio of tall to dwarf was about 3:1. From this, he postulated that there are now laws governing inheritance.The law of independent assortment and law of segregation.

Explanation:

An hormone agonist is a compound/molecule that can bind to the hormone specific receptor leading to the activation of the endocrine gland, the biosynthesis of secreted hormone and the eliciting the physiological effects of such hormone. Androgenic anabolic efficacy  of steroids is usually goverened by their receptor binding andspecificity and their biotransformation from active to inactive form.
