Why does the body attack a transplanted organ?

Biology
1 answer:
Alexxx [7]3 years ago
6 0

Answer:

A body attacks a transplanted organ because it does not recognize it as being made of self cells. It knows this because the new organ has antigens, a form of proteins that coat the organ. When a body's immune system recognizes these antigens and they are not similar enough to the body's own antigen's, it attacks to try and keep itself safe and healthy.

Light in the understory is______, which promotes conversion of phytochrome to the _____form. Please choose the correct answer fr
Tju [1.3M]

The question does not have the option which are:

depleted in red light; inactive form

enriched in red light; active form

depleted in red light; active form

enriched in red light; inactive form

depleted in red light; inactive form

Answer:

depleted in red light; inactive form

Explanation:

The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.

The light that reaches the lower portion or in the understory is depleted in the red light wavelength.

The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.

Thus, the selected option is correct.

The biochemical analysis of different chlorophyll pigments in plants would be most useful in determining <span>D. which plants might have a common ancestor.
The field of biology that deals with the similarities between these plants is called comparative biochemistry. If these plants have similar DNAs, then they are more closely linked in evolutionary terms, and thus it is quite possible they have the same predecessor.

Answer:

the making of a polypeptide with a specified order of amino acids using an ​ RNA ​molecule to provide the sequence information

Explanation:

<u>Translation is the making of polypeptide with a specified order of amino acids using a RNA molecule to provide the sequence information.</u>

In order word, translation is the process of synthesizing protein from mRNA synthesized from DNA template.

<em>During the process of gene expression, the information in the DNA are first transcribed into a mRNA in the nucleus. Thereafter, the mRNA is transported out of the nucleus to the cytoplasm where the genetic codes present in it are translated into their respective amino acids and become linked together through a peptide bond.</em>

Each polypeptide formed has a specific amino acids which correspond to the codons on the mRNA.
