Well,
By the word "deletion" we can deduce that information is lost. Therefore, when a chromosome undergoes a deletion mutation, information is lost. This can have disastrous effects if it is a human chromosome.
Answer;
a segment of chromosomal DNA
Explanation;
A gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
It is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Alleles are forms of the same gene with small differences in their sequence of DNA bases. These small differences contribute to each person’s unique physical features.
The carrying capacity of a biological organism in the surrounding refers to the maximum size of the population of the organism that the environment can maintain indeterminately, given the habitat, food, water, and other essential requirements in the environment.
When a deep water island of marine debris is situated directly in the migratory path of a pod of humpback whales, then the carrying capacity for the region would be negotiated and the populations of whale will suffer.
Answer:
The secondary immune response is the immune response when the same antigen , memory cells that was encountered before is remembered and the immune system make antibodies to counter it.
Explanation:
There is a difference between the primary immune response and secondary immune response.
In the primary immune response occur when the immune system encountered an antigen for the first time which lead to the generation of memory cells and and the B cells with the T cells produce antibodies.
While the secondary immune response occur when the same antigen that was encountered the first time is encountered the second time and it lead to the stimulation of memory cells to produce more and high quantities of antibodies to fight foreign substances.
