Answer:
This question is incomplete, the options are:
A. Two copies of the allele that determines phenotype whenever the allele is present
B. Two copies of the allele whose effect is hidden unless the other allele is absent
C. One copy of the allele that determines phenotype when present and one copy of the other allele
D. One copy of each of two alleles that both contribute equally to determining phenotype
The answer is B.
Explanation:
According to Gregor Mendel, a Gene comes in two alternative forms called ALLELES. One allele called the DOMINANT ALLELE is capable of masking the phenotypic expression of the other called the RECESSIVE ALLELE. The dominant allele will always express itself whenever it is present. However, a recessive trait will only be expressed when two alleles for recessiveness occur in the gene.
An individual whose genotype is for the recessive allele will have two copies of the allele whose effect is hidden unless the other allele is absent. This means that in that particular gene, the two present alleles will be recessive alleles.
Hi
Do prokaryotic organisms carry out cellular respiration? If so, how?
The answer is yes as well as no, because some prokaryotes like Archeae and some bacteria donot use cellular respiration because they are anaerobic. The Archaea are also known as Methanogens that reduce Carbon di oxide from environment to Methane that is eventually oxidized to NADH (that is used as an energy source).
However, there are some bacteria that use cellular respiration as a source for the energy production.Cellular respiration is a process which occurs in the cells of higher living organisms as well as in cells of some small organisms like Bacteria. During process of cellular respiration in bacteria, glucose is broken down with the help of oxygen into water and Carbon di oxide. In the process of cellular respiration, bacteria just like humans goes through three stepsi.e Glycolysis, Kreb cycle and Electron transport chain that ultimately lead to the production of ATP (energy).
Hope it helps!
Answer:
Due to convergent evolution/ analogy
Explanation:
Analogy in evolution is the development of similar or analogous structures in distantly related species occupying the same environment. This is because the species have developed similar adaptations, over time, that enables them to survive in their environment.
