Answer:
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Examples include areas which have been cleared of existing vegetation (such as after tree-felling in a woodland) and destructive events such as fires.
<h2>B) option is correct </h2>
Explanation:
Natural selection is a selection pressure which operates in a population and allow the best fitted genotype to survive in changing environmental conditions and eliminate the other genotype which are not fit
In artificial selection, breeders select superior breed for the breeding purpose so that this type of selection favors the superior genotype and eliminates inferior genotype, thus leading to genetic drift
Stabilizing selection is a type of natural selection in which intermediate genotype is favored but extreme genotypes (inferior and superior) are eliminated
In the given example of pigmentation in pigeons, breeding is selectively done with intermediate pigmentation hence intermediate genotypes will be favored
Fibre is a carbohydrate that the body can not digest or assimilate
There are two types of fibre: soluble fibre and insoluble fibre with complementary health benefits.
<span>Fibre that soluble can bind to bile and cholesterol and pull it out of circulation. this can help to decrease blood cholesterol.</span>
For the answer to the question above, I think that <span>Mendeleev's eka-aluminum is what we know today as <u><em>GALLIUM</em></u></span><u><em>.</em></u>
or the era of Mendeleev is <u><em>Aluminum</em></u> which is that <span>it would <u><em>be a soft metal with a low melting point.</em></u></span>
I hope my answer helped you. Have a nice day!
