Answer:

Hypertonic

Explanation:

Hypertonic solutions have less water ( and more solute such as salt or sugar ) than a cell. Seawater is hypertonic. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

In a particular species of frogs, black spots are a dominant trait and their absence is a recessive trait. In a population of fr
swat32

The correct answer is optionD 134/200.

The frequency of the dominant allele can be calculated by the summation of the frequency of the homozygous individual frequency that has  dominant allele  and half of the heterozygous individuals, as half of the heterozygotes have dominant allele.

The frequency is no of individual of desired trait divided by total number of individual.

The calculation is shown below:frequency of dominant allele=frequency of dominant individual+\frac{1}{2} frequency of heterozygotes\\frequency of dominant allele=\frac{50}{100} +\frac{1}{2} (\frac{34}{100} )\\frequency of dominant allele=\frac{50}{100} +\frac{34}{200} \\frequency of dominant allele=\frac{2(50)+34}{200}\\ frequency of dominant allele=\frac{134}{200}
