vesna_86 [32]2 years ago
4 0

Answer:

This in effect increased the world's carrying capacity and allowed population to grow exponentially. Since 1963, however, the ratio between energy increases and population growth has narrowed. This change could restrict future population growth.

why do polysaccharides like cellulose and peptidoglycan able to resist degradation and enzymatic activity
mixer [17]

Polysaccharides like Cellulose form insoluble micro-fibrils making it resistant to degradation and enzymatic activity.

<u>EXPLANATION: </u>

  • Polysaccharides components in general broken down monosaccharides and they are very little enough to be absorbed by the body.
  • But the polysaccharide like cellulose cannot be absorbed by our body.
  • Cellulose is made up of simple polymers that form insoluble micro-fibrils results in resistant to degradation and enzymatic activity.
  • Also, molecules of each micro-fibril are so tightly packed structure and prevent the penetration of enzymes.
  • Thus, cellulose degradation requires a complex enzyme and cellulose.

The frequency of autosomal alleles K and k in a large population of snails is 0.6 and 0.4. What is the approximate genotypic fre
Flura [38]

Answer:

Option (b).

Explanation:

The frequency of alleles K and k in population are 0.6 and 0.4. The inbreeding coefficient is 0.3.

The heterozygote frequency can be calculated by the formula:

F = \frac{2Kk-H}{2Kk}

Here, K = 0.6, k= 0.4, F = 0.3 and H = approximate genotypic frequency of heterozygote Kk.

Put the values in the above formula

0.3 = \frac{2\times2\times0.6\times0.4-H}{2\times0.6\times0.4}

H = 0.36 ≈ 0.34.

Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.

Hence, the correct answer is option (b).
