Hope this helps.Good luck ✅.The picture below shows a soil texture triangle.
Image of a soil texture triangle. Each side is labeled one of the three main soil types—silt, clay, and sand—and is divided into percentages, from 0 to 100. Each point in the triangle corresponds to a different soil texture, consisting of a different combination of silty, sandy, and clay soils. For instance, the top part of the triangle contains soils that range from approximately 50 percent clay to 100 percent clay. All these different soils are considered clays. Soils located farther down the triangle contain an increasingly small percentage of clay; for example, silty clay soils are primarily silt, with more clay than sand, and sandy clay soils are primarily sand, with more clay than silt. Soils located in the middle of the triangle contain roughly equal percentages of clay, sand, and silt; these soils are called “loam.” There are silty loam soils, which contain more silt than clay or sand; clay loam soils, which contain more clay than silt or sand, and sandy loam soils, which contain more sand than silt or clay. There are also silty clay loam soils and sandy clay loam soils.

Answer:
HOCOOH
Explanation:
HOCOOH matches the structural formula to the chemical formula
The structure contains an OH group attached with the carboxylic group, so the correct option is HOCOOH.
The carboxylic group contains an alkyl chain attached to the -COOH group. By far, the most acidic organic groups are the carboxylic acids.
The carbon atom in the carboxylic acid contains a double bond with the oxygen and a single bond with the hydroxyl group.
Here, the fourth bond formed by hydrogen is with another hydroxyl group, where the carbon is again bound to the oxygen of the hydroxyl group with a single bond.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. What is the frequency of individuals that are heterozygous for this allele
In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. The frequency of individuals that are heterozygous for this allele is 0.32.
Hardy Weinberg Equilibrium Principle A stable, idealized population's constant frequency of alleles and genotypes is described by the Hardy-Weinberg equilibrium principle. In a sizable population, random mating, or spontaneous mutations are necessary for Hardy-Weinberg equilibrium.The Hardy-Weinberg equation dictates that the sum of the allele frequencies for each allele at the locus must equal 1, therefore p + q = 1. The Hardy-Weinberg equation is also written as p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is that of the "a" allele.
The homozygous genotype AA frequency is represented by p2, the homozygous genotype aa frequency by q2, and the heterozygous genotype aa frequency by 2pq in the equation.
Here, q = 0.2. Because of this, p = '1- q = 1 - 0.2 = 0.8.
The population of individuals who are heterozygous will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.
Hence, This indicates that the population is heterozygous with a frequency of 0.32.
