For this problem, the most probable and the most likely answer for this would be the second option which is cells.
When viewing, not just corks, but other things under a microscope, may it be a home-made one or of something in value or a technologically advanced microscope, small compartments would always be visible under these lenses and they are cells. Some might look like boxes but they are cells. These cells might come in many sizes, but they will always be cells. Cells are everywhere.
Answer:
While penetrance is a quantitative estimate, reduced expressivity (transmission) is a qualitative estimate.
Explanation:
<u>Penetration
</u>
Some individuals who carry the deleterious allele (for example, in an autosomal dominant disease) do not show the expected phenotype: in that case we say that the penetrance is incomplete. This is the case in which the number of individuals presenting an abnormal phenotype is less than the number of individuals carrying the mutation causing this phenotype. Penetrance is a quantitative estimate.
For example, in the case of neurofibromatosis type I, its penetration is estimated to be 80% although it is often difficult to detect mild variants of the disease. Therefore, in these cases it would be useful to be able to detect the different mutations in the affected families and thus establish more precisely the value of their penetrance.
<u>Expressiveness (transmission)</u>
The observed phenotype can be more or less severe among the different affected individuals. In this case it is said that the deleterious allele has a variable expressiveness. Expressiveness is a qualitative estimate.
In the case of Marfan syndrome, for the same mutation present in a family, some individuals show a severe form of the disease that affects the cardiovascular, ocular and skeletal system while others show only a high height and arachnodactyly, without eye problems or of aortic aneurysm.
Reduced penetrance and incomplete expressivity are mainly described in autosomal dominant diseases.
Do not confuse an isolated case due to poor penetrance with a sporadic case due to the appearance of a mutation.
Explanation:
Both flukes and tapeworms are parasites with vertebrate hosts, including human hosts. Flukes live in the host's circulatory system or liver. Tapeworms live in the host's digestive system.
The crust must have continental (granitic) plate and oceanic (basaltic) plate to cause both explosive (granitic magma) and non-explosive (basaltic magma) eruptions.
An organism that supplies matter and energy, also known as a autotroph, is called plant I guess
