Answer:
a. Documenting species
Explanation:
first half of the century, time in which primarly scientists the discovery of the depth and size of the ocean.
<span>When river water is no longer flowing downhill, the water slows down. This makes sediment drop to the bottom. Sediment deposited where a river flows into an ocean or lake builds up and a landform called a delta is formed.</span>
Answer:
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Explanation:
Trypsin and chymotrypsin are known as proteolytic enzymes which are actively involved in the digestive system. They are both secreted by the pancreas and are majorly involved in the breakdown of protein in the small intestine.
Trypsin cuts at lysine and arginine amino acid residues at the carboxyl end. Chymotrypsin cuts at tryosine , phenylalanine, and tryptophan amino acid residues at the carboxyl end.
Answer:
Oncogenes.
Explanation:
Cancer is the harmful disease that causes several death in the world. Cancer occur due to the mutation in the genes that are responsible for the regulation of apoptosis and cell divisions.
The virus are also oncogenic in nature and can cause several different type of cancer. The human papilloma virus can be transmitted from the skin contact. The virus cause cervical cancer and genital warts. The integration of this virus into host genome increases the expression of viral oncogenes in the host DNA.
Thus, the answer is oncogenes.
Answer:
4 possible combinations of gametes
Explanation:
The animal is considered an heterozygotic dihybrid because it involves two genes that have different alleles for both genes. The dihybrid animal undergoes meiosis to produce gametes. According to Mendel in his laws of segregation and independent assortment, the alleles of the two genes separate into gametes independently of one another to produce 4 types of gametes.
Number of possible combinations of gametes formed by an heterozygote can be determined by using 2^n, where n is the number of characters. Number of characters or genes involved in this case is 2, Hence, 2^2 = 4 gametes.
The allelic combination in the four gametes are: AB, Ab, aB, ab.
