They get the food they need by making photosynthesis getting their energy and food from the sun and to grow bigger moss plants make new cells through mitosis

<span>Mosses receive their water from rainfall and most of their nutrients are dissolved in this water that has accumulated as dust on them. Their nutrient uptake is effected by the osmosis. Highly concentrated nutrients can kill them because they have no ability to regulate the absorption.</span>

lbvjy [14]

Answer;

A Both make it possible for the conditions in the interior to be different from the conditions outside.

Explanation;

Groups of molecules called microspheres may have preceded the living cells of today. Microspheres are tiny bubbles filled with groups of large organic molecules; they can form under very specific conditions. These microspheres may be a lot like the vesicles formed from the organic compounds taken off of the modern meteorites. Microspheres are not cells, but they do share some characteristics with cells.

These bundles of molecules are able to maintain an internal environment different from the surroundings outside the bubble. They also have a simple way of storing and releasing energy. They expand by absorbing additional molecules until they reach an unstable size, and then they split into smaller microspheres. This division is not true reproduction or cell division, but it may be a precursor to it.

The question is incomplete as the frequency of alleles is not given, however, the frequency and population are given below :

Frequency of a = 0.506

total population = 500, Number of aa = 128

Answer:

The correct answer is - option C. 0.336.

Explanation:

Let, A = Normal allele, a = Defective allele

So, AA & Aa will develop normal phenotype & aa will develop defective phenotype.

Frequency of a = 0.506

So, Frequency of A = 1 - 0.506 = 0.494

So, frequency of AA = (0.494)2 = 0.244036

So, frequency of Aa = 2 x 0.494 x 0.506 = 0.499928

so, frequency of aa = (0.506)2 = 0.256036

total population = 500, Number of aa = 128

So, Number of AA = (0.494)2 x 500

= 122.018 which is almost 122 so considering it 122

So, Number of Aa = (2 x 0.494 x 0.506) x 500

= 249.964 which is almost 250 so considering it 250

It is given that, Relative fitness of AA (W11) & Aa (W12) is 1, and the relative fitness of aa (W22) is 0.

Now, mean fitness = (Frequency of AA x Fitness of AA) + (Frequency of Aa x Fitness of Aa) + (Frequency of aa x Fitness of aa)

= (0.244036 x 1) + (0.499928 x 1) + (0.256036 x 0) = 0.244036 + 0.499928 = 0.743964

So, after selection frequency of Aa

= (Frequency of Aa x Fitness of Aa) / mean fitness

= 0.499928 / 0.743964 = 0.67198 (Up to 5 decimal)

So, after the selection frequency of aa

= (Frequency of aa x Fitness of aa) / mean fitness

= 0 / 0.743964 = 0

So, frequency of a

= 1/2 of frequency of Aa + Frequency of aa

= 1/2 x 0.67198 + 0

= 0.33599 + 0

= 0.33599 which is almost 0.336
