Answer:
Microorganisms.
Explanation:
They break down dead things and release nitrogen back into the soil and atmosphere.
Hello!
The parts of the central nervous system (CNS) include only the following:
Most of the other parts we associate with the nervous system are part of the PNS, or the peripheral nervous system.
I hope I helped!
Natural Selection, unless you were born in a lab which would be unnatural/artificial, and not too likely with today's technology. (Maybe one day.)
Answer:
Complementation.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her. Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Complementation can be defined as a relationship between two strains of a living organism both having distinct homo-zygous recessive mutations and results in the expression of a wild-type phenotype when crossed or mated.
In this scenario, there are two different varieties of a snapdragon flower having golden leaves rather than green leaves. Thus, crossing two different varieties of golden snapdragons would produce offsprings that have green leaves.
Hence, the above breeding is an example of complementation.

Asexual reproduction does not produce variety in population, unless through mutations, because offspring are exact copies of their parent – because they reproduce by binary fission.
Explanation:
Sexual reproduction produces variations by genetic combinations. Remember during meiosis, there is the crossing over of chromosomes. In addition during fertilization, in sexual reproduction, each gamete brings in alternative forms of alleles of genes. The advantage of asexual reproduction is that it allows for fast reproduction because only one parent is involved in the formation of offspring.
