Answer:
They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed.
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.
Answer:
The primary function of the centromere is to provide the foundation for assembly of the kinetochore, which is a protein complex essential to proper chromosomal segregation during mitosis. In electron micrographs of mitotic chromosomes, kinetochores appear as platelike structures composed of several layers
Only 10 percent of the energy available within one trilogy level is transferred to the next trophic level.
Answer:
Referring to the attached figure, there are two alleles V and v for height. The reason for using capital and small letters is to indicate the dominant or recessive nature of the allele.
<u>Explanation:</u>
Dominant (V):
An allele that is dominant means only one copy of that allele is enough for the expression of trait. For example, if V is for tall height, an individual with genotype Vv or VV both will have tall height because they have the allele of tall height that is dominant in nature.
Recessie(v):
An allele that is recessive nature means two copies of that allele are mandatory for the expression of trait. For example, if v is for short height, an individual with genotype vv will have short height because they have two copies of same alleles that are recessive in nature. However if the genotype is Vv, still the individual will have tall height because capital letter is masking the effect of small letter (v allele). This is because of recessive nature of allele.
