Answer:

none of these

Explanation:

because no.of proton+no.of neutron=atomic mass

therefore in zinc no.of protons(30)+ no.of neutrons(35) =atomic mass(65)

therefore the no.of neutrons in zinc is 35

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).

Blizzard [7]

There are three types of muscle tissue: Visceral, cardiac, and skeletal. Visceral Muscle. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. The major types of muscle systems are the skeletal muscles, cardiac muscles and smooth muscles. The skeletal muscles are voluntary muscles, whereas the smooth and cardiac muscles are involuntary ones.
