Answer:
Biotic Limiting Factors
These limiting factors can be further broken down into abiotic or biotic limiting factors. Abiotic factors are non-living physical and chemical elements in the ecosystem, such as sunlight, temperature, soil, water, and oxygen
Answer:
5, 3, 4, 1, 6, 2
Explanation:
When B cells encounter an antigen, they bind to it and internalise it through the process of phagocytosis. The antigen is then degraded and digested and presented on the surface of the b cell with MHC II molecules. Activated b cells are called Antigen presenting cells.
Activated B cells circulate through the lymph nodes and interact with helper CD4 T cells of the Th2 subtype. The CD4 T cells recognise the antigen on the MHC II and secrete cytokines on the B cells to induce proliferation and expansion of the B cells.
The B cells differentiate into plasma cells and plasma cells begin the secretion of antibodies of the IgM isotype.
to imitate and manipulate conditions that organisms would encounter in the natural world
Answer:
of blood plasma was “cleared”
Explanation:
Given,
Concentration of a person’s blood cortisol µg/mL
The amount of cortisol excreted from the body in a period of 24 hour mg
The volume of blood plasma cleared during this time period is equal to
amount of cortisol excreted from the body divided by Concentration of a person’s blood cortisol
The above definition could be represented as following-
volume of blood plasma cleared
Where A represents amount of cortisol excreted from the body
while B represents the concentration of a person’s blood cortisol
Substituting the given values in above equation, we get -
of blood plasma was “cleared”
Answer:
This composition of nucleotide given in the question do not obey the chargaff"s rule.
Explanation:
According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is
Adenine+Guanine=Thymine+Cytosine
But here the above quation is not maintained because according to the question A+G=49%
and T+C = 51%.
Such DNA is replicated by rolling circle model.
