Surgical removal of the innermost layer of the artery is called

1 answer:

4 0

The excision of the gland is Adenectomy (Aden means "gland" and ectomy means "surgical removal"). Removal of plaque (lipids and clots) that accumulate in the lining of an artery. Endarterectomy is a surgery to get rid of the adipose tissue plaque material, or blockage, within the lining of associate degree artery constricted by the buildup of deposits. it's administered by separating the plaque from the blood vessel wall.So, don't get confused with both the terms.

Which of the following is a common treatment for type III hypersensitivity reactions?

mestny [16]

Answer:

Anti-inflammatory steroid treatments

Explanation:

The exaggerated or hyper active response of the immune system causes hyper sensitive reactions in the body. These immune reactions are generally uncomfortable and harmful for the body.

Type III hypersensitivity reaction mainly occur due to the neutrophils, IgG and complement. This hyper sensitivity reaction can be treated by anti-inflammatory steroid treatments as the neutrophils are the main mediators of this reaction.

Thus, the correct answer is option (1).

Each row in the auditorium has 18 seats and 246 and teachers are going to watch an assembly in the auditorium how many rows of s

Romashka-Z-Leto [24]

Explanation:

We will divide the total number of the teachers (246) in the auditorium with the maximum number of seats per row (18) to determine how many rows are completely filled;

246/ 18 = 13.6667

We are only interested in rows that are completely filled which is the whole number;

= 13

Analyze the data about nitrogenous base content of DNA from various species. Percentages of Bases in Five Organisms Source of DN

Troyanec [42]

Answer:

When analyzing data on the nitrogenous base content of the DNA of various species, the claims are supported by the data:

In any one species, the amount of adenine closely approximates that of thymine.
In any one species, the amount of guanine closely approximates that of cytosine.
The amounts of A, T, G, and C in DNA varies from species to species.

(options A, B and D)

Explanation:

Organizing the data has to:

Source of DNA A T G C

Streptococcus 29.8 31.6 20.5 18.0

Yeast 31.3 32.9 18.7 17.1

Herring 27.8 27.5 22.2 22.6

Human 30.9 29.4 19.9 19.8

E. Coli 24.7 23.6 26.0 25.7

DNA is the molecule that contains the genetic information of each species, formed by sequences of nitrogenous bases Adenine, Thymine, Cytosine and Guanine.

Since Adenine and Thymine -as well as Cytosine and Guanina- are complementary, the percentage of them will be very similar in each DNA molecule.

The genetic information -which determines the physical and functional characteristics of each organism- is encoded in the DNA and is different for each species, so the percentages of nitrogenous bases vary from species to species.

Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynucleotide

mr Goodwill [35]

The question is incomplete as it does not have the options which are:

(a)DNA (b)tRNA (c)rRNA (d)mRNA

Answer:

Option-mRNA

Explanation:

The mRNA is synthesized from the DNA and which is also a type of nucleic acid. When the nucleic acid is extracted from the yeasts and then mixed with the resin beads to which the polynucleotide with thymine base oar is attached.

The mRNA will bind to the resin bead as the mRNA after synthesis undergoes modification and attaches poly A tail to the end of the mRNA at 3' end.

This poly-A tail has adenine which easily binds to the thymine and thus mRNA easily attaches to the resin bead.

Thus, mRNA is correct.
