In Kerr and Wright's experiment with 96 fruit-fly populations, only 4 males and 4 females bred in each generation. After 16 gene
Svetradugi [14.3K]

Answer:

2.Less than 73% of the populations would have only one allele present.

Explanation:

The two alleles chosen do not affect the fitness of flies in the lab environment, so Kerr and Wright could be confident that if changes in the frequency of normal and forked phenotypes occurred, they would not be due to natural selection.

Using a larger breeding population would not be expected to alter the outcome of the experiment.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2​
marissa [1.9K]

Answer:

A 0.015M

Explanation:

Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:

Molarity (M) = mole (n) / volume (L)

Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.

We can calculate the number of moles of KCl in the solution by using the formula:

Mole = mass ÷ molar mass

Where atomic mass of; K = 39, Cl = 35.5

Molar Mass of KCl = 39 + 35.5

= 74.5g/mol.

Mole = 0.83g/74.5g/mol.

mole = 0.01114

Approximately, n = 0.011mol

Hence, molarity = 0.011mol/0.75L

Molarity = 0.0146

Molarity = 0.015M
