Answers

Answer:

(Sorry messed up the first time and didnt put an explanation) Four

Explanation:

It is four because there are three nucleotides in a set to make an amino acid. This would make 15 divided by 3, which is 5, but the last one is the code for stop (that is, to tell when a new chain for protiens should start), and that doesn't count as an amino acid.

The _____________ receives blood from the atrium and pumps it out of the heart.

Answers

I’m pretty sure it’s the left ventricle but if not then choose another answer

Ventricles receive blood from the atrium and pump it out of the heart. The left ventricle pumps oxygenated blood to different parts of the body.

How does the heart pump blood?

The heart has four chambers, such as the upper two atriums and the lower two ventricles. The right side of the heart holds the deoxygenated blood, and the left side holds the oxygenated blood.

The deoxygenated blood from different parts of the body is poured into the right atrium through the superior vena cava, inferior vena cava, and coronary sinus. Then, from the atrium, blood moves to the ventricle through the atrioventricular opening.

From the right ventricle, blood moves to the lungs for oxygenation through the pulmonary artery. In the lungs, the oxygenation of blood takes place, and the oxygenated blood comes to the left atrium. From the left atrium, the oxygenated blood comes to the left ventricle. From the left ventricle, blood goes to different body parts through systemic arteries.

Hence, the ventricles receive blood from the atrium and pump it out of the heart.

Likewise, natural killer cells target human cells for destruction. Explain why it is advantageous for the immune system to have cells that can kill human cells as well as pathogens.

Answers

Answer:

Because Neutrophils has many other functions like

Neutrophils are the most abundant granulocytes that makeup about 40% of white blood cells and 60% of the immune cells in the blood.Neutrophils are the first responders to infection, and they phagocytose bacteria into phagosomes before hydrolyzing and destroying them.These cells also secrete a range of proteins that have antimicrobial effects as well as tissue remodeling potential.Neutrophils have a short lifespan and thus destroy themselves during the degradation of foreign invaders. New neutrophils are then produced continuously in the bone marrow.The neutrophils of another subpopulation, cager neutrophils, perform a transport function of delivering foreign particles to the target site for the action of killer neutrophils.

Like wise Natural killer (NK) cells are effector lymphocytes of the innate immune system that control several types of tumors and microbial infections by limiting their spread and subsequent tissue damage.

if a strand of DNA has the sequence ATGCGATCCGC, then the sequence of the MRNA molecule transcribed from it is​

Answers

Answer:

DNA:      ATGCGATCCGC

mRNA:   UACGCUAGGCG

             

Explanation:

The deoxyribonucleic acid (DNA) is a double-stranded helix, where each strand is composed of four nitrogenous bases: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). The two strands are held together by hydrogen bonds and they interact in the following way: Adenine (A) always pairs with Thymine (T) through two hydrogen bonds, while Guanine (G) always pairs with Cytosine (C) through three hydrogen bonds. During transcription, a DNA strand of the double helix DNA molecule is used as template to synthesize a complementary RNA molecule, usually, a messenger RNA (mRNA) which is then used to create a protein by the process of translation. Moreover, also during transcription, Thymine (T) bases are replaced by Uracil (U) bases in the RNA molecule.

how do the ocean zones compare with one another

Answers

There are three main ocean zones based on distance from shore. They are the intertidal zone, neritic zone, and oceanic zone. Distance from shore influences how many nutrients are in the water. Most nutrients are washed into ocean water from land. Therefore, water closer to shore tends to have more nutrients. Living things need nutrients. So distance from shore also influences how many organisms live in the water.

A chemist weighed out 101. g of beryllium. Calculate the number of moles of beryllium she weighed out.

Answers

Answer:

The correct answer is - 11.209 moles.

Explanation:

According to the definition of moles,

moles = weight/molecular weight

given:

weight of beryllium = 101 g

the molecular weight of beryllium = 9.01

∵ 9.01 g weight of beryllium = 1 mole

∴ 1 g weight of beryllium = 1/9.01 moles

∴ 101 g of beryllium =101/9.01  moles

The = 11.209 moles.

If a diploid eukaryotic cell contains 14 pairs of chromosomes for a total of 2n=28, how many chromosomes will be in the resulting products of cellular division if the cell undergoes:
Mitosis?
Meiosis?

Answers

Answer:

Mitosis = 28 chromosomes

Meiosis = 14 chromosomes

Explanation:

- Mitosis is the type of cell division in which the daughter cells are genetically identical to the parent cell and possess the same number of chromosome as the parent cells. For example, a diploid parent will produce a diploid daughter cell after mitosis.

- Meiosis, on the contrary, is the cell division that produces daughter cells that are genetically different from the parent cell. Each daughter cell have a reduced number of chromosomes (by half).

According to this question, a diploid eukaryotic cell contains 14 pairs of chromosomes i.e. 2n=28. After mitosis, each daughter cell will have same 28 chromosomes as the parent cell. Meiosis on the other hand, will produce daughter cells that possess 14 chromosomes each.
