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 .

Answer:
sensor
Explanation:
Homeostasis refers to the ability of an organism to maintain the internal conditions of the body irrespective of the external conditions.
The homeostasis is maintained by the homeostatic mechanism which involves the 3 components which are the receptor or sensor, the integrating centre and the effector or organ.
In the given question, the peripheral chemoreceptors measures and sense the pH of the blood therefore the peripheral chemoreceptor will be considered as the "sensor component" of the homeostatic mechanism.
Thus, the sensor is the correct answer.
All species of Great Ape have 48 chromosomes, which is one more pair than humans. Both monkeys and Great Apes reproduce sexually, giving them a Haploid and Diploid number. The Haploid number is half of the Diploid number. It is the number of chromosomes found in a sex cell, or the number of chromosome pairs. The Diploid number is the number of chromosomes in a cell which is not an egg cell or a sperm cell.
