How the
immune system works, explain why injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease.
Answer:
Our immune system produces antibodies against that antigen of pathogen.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

If a widow’s peak (W) is controlled by a dominant allele and a straight hairline (w) is controlled by a recessive allele, how would you describe a person whose genotype is Ww?
Answer:
The correct answer is - a heterozygous individual with widow's peak.
Explanation:
In the given case, the dominant character is the widow's peak that is represented by the allele W and the straight hairline is a recessive character represented by the allele w. So, if an individual has both dominant alleles WW it means this individual has widows peek as W is the dominant allele and if this individual has ww allele it means the straight is expressed as no dominant allele to mask the effect of recessive allele w.
In the case of heterozygous that means one copy of dominant and one copy of recessive allele is present that is Ww then this individual have a widow's peak due to the fact that dominant allele will mask the effect of recessive allele.
.What might happen to cells with DNA that has been damaged by an environmental influence such as UV light from the sun or a tanning bed?
Answer:
It can lead to melanoma or a time of skin cancer.
Explanation:
This is because UV radiation in sunlight can destroy the DNA by destroying the base pairing. UV light will cause two Thymine that are very closer to each other to join together to produce dimer. After which, The melanin-assisted process form lesions that is popularly called cylobutane pyrimidine dimers in DNA, which can result in mutations that cause melanoma which is a form of skin cancer

PLZ HELP!Which option is the most exact conclusion about the agricultural methods being used in the following scenario?
An entomologist performs an extensive survey of insect life on an agricultural site. The results show a large and very diverse range of beneficial species, pest-species, and neutral insects filling all possible roles and suited to many microenvironments. The diversity is shown within both small, single site samples and across the board in all sampling sites.
The methods are those of extensive monoculture.
The primary pest management system is trapping and mechanical removal.
The land has been developed using only crop rotation as a polyculture technique.
The methods are those of intense polyculture.

So, option D is correct answer..Chromosomes 1 - 22 are called autosomes and code for all of the processes in the body except the genes that determine gender characteristics. How many total autosomes does Subject A have?
Humans exhibit twenty-two (22) pairs of autosomes or autosomic chromosomes which are distinct from sex chromosomes X and Y.
What is an autosome?An autosome can be defined as any chromosome in a somatic/germinal cell that is not a sexual chromosome (i.e., autosomes are not x chromosomes and Y chromosomes).
Autosomes contain essential genes required both in women and men in order to synthesize structural and enzymatic proteins present in their cells.
In conclusion, Humans exhibit twenty-two (22) pairs of autosomes or autosomic chromosomes which are distinct from sex chromosomes X and Y.
