Describe the function of each of the following in protein synthesis; rRNA, mRNA, and tRNA

Answers

Answer 1

Answer: Proteins synthesis requires transcription of DNA (containing information) to mRNA then this goes out of the cell’s nucleus to cytoplasm; and translation of mRNA together with ribosome and tRNA to synthesize proteins. Further steps are the following: 1) One side of DNA strand is copied to become mRNA (messenger RNA). 2) mRNA goes out the cell’s nucleus, next to cytoplasm and then to ribosome. 3) mRNA works with ribosome’s 3 bases at the same time. 4) tRNA (transfer RNA) connects with available DNA bases. 5) tRNA releases the amino acids which in turn combines with the other produced amino acid chains from different DNAs.

Answer:

Histological examination

Explanation:

This sample can then be sent to a lab for histological examination , so the cells can be observed under a microscope for abnormalities.

Histological examination Involves the careful analysis of cells and tissues usually under a microscope to determine if there is any problem.

The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."

b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."

c. "Her alveoli have been damaged and may rupture with higher doses of O2."

d. "Her respiratory center requires low O2 concentration to stimulate breathing."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."

In patients with COPD, the respiratory drive is stimulated by hypoxemia, not increased levels of carbon dioxide. Administration of oxygen in high levels will impair the respiratory drive.

Answers

The question is incorrect. The correct question is as follows:

a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."

b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."

c. "Her alveoli have been damaged and may rupture with higher doses of O2."

d. "Her respiratory center requires low O2 concentration to stimulate breathing."

Answer:

Her respiratory center requires low O2 concentration to stimulate breathing."

Explanation:

COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.

The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.

Thus, the correct answer is option (d).

Which mechanism of genetic variation results from the exchange of gene segments between non-sister chromatids? Select one of the options below as your answer: A. Crossing over
B. Independent assortment
C. Random fertilization

Answers

A) Crossing over is the mechanism of genetic variation that results from the exchange of gene segments between non-sister chomatids.

Crossing over occurs between prophase 1 and metaphase 1 and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. It can also happen during mitotic division, which may result in loss of heterozygosity.

Flatworms have a concentration of nerve tissue and organs in one end of the body. what is the name of this characteristic,

Answers

Answer:

The correct answer is cephalization.

Explanation:

Being a evolutionary feat, cephalization is umbrella term for concentration of sense organs such as eyes and ears, feeding organs such as mouth and nervous system such as ganglia, brain and cerebellum. For flatworms the ganglia concentrated in one end of the body which is "nerve tissue" in your question.

This is called cephalization. In mammals, this cephalization occurs primarily in the head...brain, eyes, ears, mouth.
