The substance which contains two molecules of hydrogen and one molecule of oxygen it is called water.
<h2>Explanation:</h2>Water is the universal solvent which is used in all sort of metabolic, biological, and chemical activities. It is a liquid with pH 7 and lacks definite shape but has definite volume. It has no taste or color or odor.
The chemical formula of water is , which means that it is the substance which is formed by the addition of two atoms of hydrogen element with one atom of oxygen element.
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 =
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 =
H = 0.36 ≈ 0.34.
Thus, the approximate genotypic frequency of the heterozygote Kk is 0.34.
Hence, the correct answer is option (b).
