Compare: They are both living organisms.
contrast: Autotrophs make their own food. But heterotrophs can not make their own food.
Answer: The term <em>parent material</em> is weathered rock that becomes soil. The answer is <em>A. </em>
Explanation:
There are a total of 7 types of the parent material. The seven types are; outwash deposits, eolian sand, loess, local area overwash, bedrock that has been weathered over time, till, and alluvium.
This material is made up of living organisms, time, climate, and topography.
A neuron is the structural and functional unit of the nervous system involved in conduction of nerve impulses. It is divided into cell body, dendrites and axon. Cell body or the soma has the cell organelles and the nucleus and the two processes called the axon and dendrites emerge from the cell.
If a neuron is compared to an electric cord, the myelin sheath can be compared to the insulator of the electric cord. Myelin is a lipid rich substance that insulates the nerve axons. The myelin sheath insulates the nerve axons to increase the speed of transmission of nerve impulse. It is formed by the concentric wrapping of Schwann cell around the axon.
Pheromones used in reproduction are not likely to be found in organisms that only reproduce asexually.
The chemicals called pheromones are used to communicate between members of the same species and cause the recipient to react physically or behaviorally. Pheromones are a subset of organisms' larger class of chemicals to communicate, known as semiochemicals, from the Greek <em>semeon</em>, meaning signal or mark.
Animals communicate chemically constantly, with pheromones mediating more interactions than any other type of signal. The majority of pheromone research has been conducted on insects, particularly species that are considered pests.
For these, using pheromones that alter their behaviour in various ways might be employed for population control, pest management, or monitoring.
