Answer:
Producing transgenic animals has practical advantages, such as using less than half of experimental animals for the production of an envelope.
Explanation:
Currently it is only possible to add genes, the transgenic sheep that exist are found to produce human proteins. However, it is convenient for some proteins to remove endogenous proteins from milk. For example, for human serum albumin.
There is a high demand for some human proteins for the treatment of various diseases. Small quantities can be produced in cell cultures but the cost is very high. Higher amounts can be made by bacteria or yeasts, but proteins are difficult to purify and that is why some of the advantages of having transgenic animals is the amount of protein produced.
B)bone structure
C)cellular architecture
D)homologous structures
Answer:
A dna sequences
Explanation:
species have genetic
One of the major elements of natural selection is that all species have genetic variation.
There must be some evolutionary means by which existing DNA sequences are changed and new sequences are incorporated into the gene pools of species called genetic variation.
Natural selection is a process when organisms adapt better to their environment. It is an essential key in evolution. There is a change in phenotype of a population over time.

No, because histone modifications do not affect transcription
No, because the results demonstrate only a correlation between altered histone modifications and reduced transcription
Yes, because the observed changes in histone modifications are consistent with reduced transcription.
Yes, because histone modification is the only regulatory mechanism that could affect transcription
B. receptor proteins.
C. antigens.
D. macrophages.
Antibodies are produced when the body is exposed to antigens.
During an initial encounter with a foreign antigen, the body's immune system namely the adaptive arm of the immune system, produces memory cells, a group of special lymphocytes that retain and store memory of the antigen.
On a second encounter with the same kind of antigen, the immune system "remembers" the antigen and mounts a rapid, specific and vigorous immune response against the antigen. This response includes the production of massive amounts of antibodies very specific to the antigen.
The antibodies effectively neutralize the antigen and facilitate its destruction.
Answer:
C. Antigens
Explanation:
Antibodies a protein formed by immune-responsive cells that is specific for a particular antigen and can bind to it to inactivate or destroy it.
Hope that helps!!
