The physical appearance of the biochemical characteristic of an organism as result of the interaction of phenotype; some mutation has the positive effect on the organism in which they occur.
<u>Explanation:</u>
They are called beneficial mutation. Phenotype of the organism lead to new development of proteins which help the organisms to adopt their own environment. Beneficial mutation are essential for evaluation to occur.
Phenotype stretch the DNA without any function; the mutations occur in a protein coating region, but it end up the process by not affecting sequence of the protein.
Example of phenotype are:
Observable characteristics including behaviour, biochemical properties; the phenotype benefits such as HIV resistance, lactose resistance.
Answer:
The correct order would be:
A vaccine introduces a weakened flu virus into the body.
↓
The immune system identifies antigens on the weakened flu virus.
↓
Antibodies are produced, which bind to the weakened flu virus and signal immune cells to destroy it.
↓
The actual flu virus enters the body, and lymphocytes recognize the antigens.
↓
Antibodies are quickly produced and allow the body to fight off the infection.
Vaccination or immunization is the process which helps in developing the immunity (adaptive) against a particular pathogen or microorganism.
It includes the administration of antigen, weakened or heat-killed microorganism (such as flu virus) into the patients body. Body's immune system produces naive B and T cells to eliminate the antigen.
This encounter enables the immune system to produce memory B and T cells against that particular pathogen.
In future, whenever the same antigen enters the body, the immune system gets activated quickly due to the presence of memory cells. It enables the body to produce more effective secondary response against the pathogen.
Answer:
A. It contains fewer volatile gases.
Explanation:
Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.
The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.
What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.
The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.
The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.
According to Peter Berger, there are four major characteristic of modernization. They are
1. The expansion of personal choice.
2. The decline of traditional and small communities
3. Increasing social diversity
4. Growing awareness of time and orientation towards the future.
I hope this answers your question.
