Answer:
Antigens, and epitopes.
Explanation:
Antigen is known as a substances which is capable of the causes an immune response in the body, and specifically activating white blood cells which are known as body's infection fighting cells. In general antigens are two types:
1) Foreign antigens or heteroantigens.
2) Auto-antigens or self antigens.
Epitopes are the part of an antigen which is recognized with the help of immune system, specifically by B cells, T cells, and antibodies. They are also called as antigenic determinants. The epitope is defined as the specific part of the antigen where an antibody binds.
answer:
by having a high genetic level of melanin in your skin, you're skin is more protected from the ultra violet sun rays. Darker skinned races have more melanin present, these races originate from hot countries where sunlight is often present; the production of melanin in their skin allows them to reflect and inhibits they're skin from becoming extremely damaged. Light skinned races don't have a large amount of melanin due to they're native countries lacking sunlight. This is an evolutionary adaptation of the human race.
Answer:
The answer is C. The way Douglass explains his situation gives off mysterious vibes than anything else. sorry if it's wrong! (┬┬﹏┬┬)
Answer:
The correct answer will be option-C.
Explanation:
The process of translation in prokaryotes is complex process and proceeds in three steps: initiation, elongation and termination.
1. Ribosomal subunits: 50S (5S and 23S subunit) and 30S (16S and proteins).
2. Initiation factors: IF1, IF-2 and IF-3 which help in the formation of assembly.
3 GTP: guanosine triphosphate as a source of energy.
4. Charged tRNA: with N-formylmethionine is the first amino acid.
5. mRNA: the RNA to be translated.
Since the option contains both 50S and 16S components of ribosome thus, Option-C is the correct answer.
Chloride and sodium, I believe. Chloride and Sodium are believed to be salty, and this concentration makes up 90% of all dissolved ions in the ocean.
