Answer:
Phoebus Levene.
Explanation:
Two types of nucleic acids are DNA and RNA. The monomers of mucleic acid contains the pentose sugar, nitrogenous bases and the phosphate group attached with the bases.
Friedrich Miescher was the first scientists who discovered the nucleic acids. He identified the nucleic acids from the bandage that contains the nuclei of white blood cells. The new compounds discovered is known as nucleic acid. But the monomers of the nucleic acids was first explained by Phoebus Levene. Different forms of nucleic acid was also postulated by Phoebus Levene.
Thus, the answer is Phoebus Levene.
<span>D is the correct answer. Coral reefs need sunlight to grow, so they grow best in shallow water (up to 50m deep) as this means sunlight can reach them. They require salt water to grow and warm temperatures of 20 - 32 degrees Celsius.</span>
<h3>yellowfish tuna</h3>
This is the fourth fastest fish, having recorded swimming speed of 76km/h.
<h3>What is Tuna known for ?</h3>
Tuna are remarkable and impressive wild animals. The Atlantic bluefin can reach ten feet in length and weigh as much as 2000 pounds (more than a horse)
- Their specialized body shape, fins and scales enable some species of tuna to swim as fast as 43 miles per hour. Tuna swim incredible distances as they migrate.
- The latest report by the UN shows that tuna is the world's most consumed and the second most wild caught fish in the world.

An immunoglobulin molecule of any class with regions symbolized as C or V, H or L, has a light chain made up of one C region and one V region.
The glycoproteins known as immunoglobulins (Ig), often known as antibodies, are created by plasma cells. A number of immunogens, including bacterial proteins, promote B cells' conversion to plasma cells. These cells, which make proteins, are involved in humoral immune reactions to bacteria, viruses, fungi, parasites, cellular antigens, chemicals, and synthetic compounds. Using a B-cell receptor, the immunogen or antigen adheres to the B cells' cell surface (BCR).
As a result, a signal is generated that directs the activation of transcription factors, leading to the manufacture of highly specific antibodies for the immunogen that initially activated the B cell. Furthermore, one B cell clone produces immunoglobulin (specificity). Two light chains and two heavy chains that alternate in a light-heavy-heavy-light pattern make up antibodies, also known as immunoglobulins. Therefore, choice A is the right response.

PMI is very important in forensics because having a time of death can help with the identification of human remains and can support or deny the stated actions of suspects in the crime.
