What is on a transplanted organ that causes the transplant recipient's body to reject it?

Biology
1 answer:
Delvig [45]3 years ago
8 0

Answer:

Major histocompatibility complex (MHC) antigens

Explanation:

The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.

A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the  transplanted organ.

Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".

The term differential count measures the amount of each type of leukocyte in your blood. The normal range of leukocytes in circu
Deffense [45]

Answer:

The correct answer will be-

1. 50–70%- Neutrophils

2.  20–40%- Lymphocytes

3.  2–8% - Monocytes

4. 1–4%- Eosinophils

5. Less than 1%- Basophils

Explanation:

Blood is a specialized connective tissue which contains three types of formed elements- leukocytes (white blood cells), erythrocytes (red blood cells), and platelets.

Five types of leukocytes are present in the blood which play an important but distinct role in the human body mainly involved with the immune response.

These leukocytes include Neutrophils, Lymphocytes, Monocytes, Eosinophils and Basophils which can be counted per microliter of blood through differential counting which shows that: 50-70% of blood leukocytes is accounted by the Neutrophils, 20–40% by Lymphocytes, 2–8% by Monocytes , 1–4% by Eosinophils   and  Less than 1% by Basophils.

ruslelena [56]

Answer:

0.25 right-handed homozygous, 0.50 heterozygous, and 0.25 recessive homozygous for a 0.5 allele frequency for each allele

Explanation:

In the Hardy-Weinberg equilibrium equation is ( p²+2pq+q²=1 ),

  • the term 2pq represents the genotype frequency of heterozygotes (Aa) in a population in equilibrium.
  • the term p² represents the frequency of dominant homozygotes (AA) and
  • the term q² represents the frequency of recessive homozygotes (aa).
