Answer:

B

Explanation:

Mendel discovered that an organism receives two forms of a gene called allele from each parent. This alleles combine to form the genotype of that organism, which in turn determines the phenotype.

Mendel crossed purebreeding plants that produced only tall and short plants respectively. He got an all tall F1 offspring. He then self-crossed the F1 offsprings to get a phenotypic ratio of 3:1 in the F2 offsprings. He discovered that the tall allele was dominant over the short allele for the height gene in pea plants. This is because the tall alleles masked the expression of the short allele in the F1 generation making them all exhibit tall traits.

The F1 are regarded as hybrids or heterozygotes because they were a mixture or combination of two different alleles. This mixture was confirmed in the F2 offsprings that produced 3 tall plants and 1 short plant, showing that the recessive allele was still present but masked in the heterozygotic combination.

An insect with coloration to avoid being detected by a predator would be an example of.
Vilka [71]

An insect with coloration to prevent from being detected by a predator would be an example of Camouflage.

<h3>What is the importance of Camouflage?</h3>

Camouflage, commonly characterized as cryptic coloring, is a defensive tactic used by organisms to obscure their appearance, generally in order to blend in with their environment.

Camouflage is utilized by organisms to hide their location, identity, and movement. This enables prey to evade predators while also allowing predators to sneak up on victims.

An insect with coloration to avoid being detected by a predator would be an example of Camouflage.

Thus, the correct answer is Camouflage.

What determines the color of soil
shutvik [7]

Answer:

Actually, the main pigmenting (coloring) agents in soils are organic matter, iron, and, to a lesser extent, manganese. When these agents are not covering the mineral grains, the natural color of the grains is visible. Colour is a simple method of classifying soil. Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure.he colour of the soil varies from one place to the other because soil is formed out of different types of rock . Since rocks are of different colours and textures , the colour of the soil varies from one place to another .
