It is because that's a place where no one lives so they're safe.
Answer:
Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
Explanation:
Humoral immunity is defined as the immunity which is mediated by several macromolecules presnet in the extracellular fluids such as antibodies, certain antimicrobial peptides, and complement proteins.
Humoral immunity allows to distinguishes two groups of foreign substances. it involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood. </u>
Humoral immunity begins when an antigens bind to B cells. Interleukins or helper T cells provides a secondary signal to the B cells that activates a B cell and allows B cell proliferation. which roduces produce plasma cells. The plasma cell then produces antibodies which are identical to the specific antigen. The antibodies are the released and circulate through the body, binding to antigens. B cells the further produces memory cellss for future immunity.
So, Humoral immunity involves <u>B cells</u> and<u> recognize antigens or pathogens in the lymph or blood.</u>
well I mean I don't know a lot but, Yes, a physician can proceed with diagnosis of a disease based on molecular biology data. It would have been easier to explain if you had shared the data with us. Molecular Biology techniques like polymerase chain reaction (PCR) is widely used for diagnostic purposes.
This is false the population density will decrease as the area decreases
The part of a DNA molecule responsible for the direct coding of specific traits in an organism is the nucleotide sequence.
<h3>How is a DNA molecule structured?</h3>
The DNA molecule is the biological molecule that stores genetic information in living organisms.
The DNA molecule is made up of three major components in its structure:
- Five carbon sugar
- Nucleotide bases
- Phosphate group
The five carbon sugar is deoxyribose while the nucleotide bases are four in number as follows:
- Adenine
- Guanine
- Thymine
- Cytosine
These nucleotides are responsible for the direct coding of specific traits in an organism.
