hiw many animals live here?
Explanation:
these are the kinds of questions asked
Answer:
a. Only the DNA of β cells contains the gene for insulin; only the DNA of chief cells contains the gene for pepsinogen
Explanation:
As stated in the question above, insulin production is exclusive to β cells in the pancreas. This is because only these cells have a gene that manages the production and excretion of insulin within an organism. Similarly, only the main cells of the stomach have the capacity to produce pepsinogen, which indicates that the gene responsible for managing this production is unique to these cells.
Answer:
The Six Kingdoms. When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells. Today the system of classification includes six kingdoms.
Explanation:
Answer:
Reduced penetrance or incomplete penetrance
Explanation:
Penetrance refers to the extend which a certain gene or set of genes is expressed in a population.
It can be complete where there is expression of the gene in a population having it.
Whereas, in reduced penetrance is where the mutation is not expressed in every individual in the population having it.
For instance polydactyly exhibits reduced penetrance since the parents had the mutation it was not expressed it came to be expressed on their pedigree.
