The lack of access to the healthy food has caused the growth of Sebastian to slow down. In the case healthy food is provided to him, he can grow into the size he was genetically suited to. This process is known as the canalization. Canalization term is used as the measure of the ability of any given genotype to result in the same phenotype in-spite of the environmental variability.
Answer:
Prokaryotic cells don't have a nucleus and Eukaryotic cells have a nucleus.
Explanation:
Answer: D) retroviruses
Explanation:
Retroviruses are a type of virus that converts its genetic material into DNA using a special enzyme, called reverse transcriptase. The DNA is then able to integrate into the DNA of the host cell. Once integrated, the virus can make additional viral particles using the components of the host cell.
Retroviruses which cause cancer at low incidence do not contain host information inserted. Rather, they tend to cause cancer via the expression mutation of potentially oncogenic host genes. Retroviruses incorporate proviral DNA into their host's chromosomal DNA during their natural life-cycle. Provirus DNA promoter affect regulatory gene expression over.
Hence, the correct option is D.
The amount of nitrogen in the bay increases with a consequent increase in the population of algae(algae blooms).
In water bodies, there are small plants that are called phytoplankton and algae. These organisms depend on dissolved nutrients to survive in water. These dissolve nutrients some times enter into water bodies through surface run off.
When runoff from farms, suburban lawns, and wastewater treatment plants a watershed gets into a local bay, the amount of nitrogen in the bay increases with a consequent increase in the population of algae(algae blooms).
