Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand
Explanation:
In semi-conservative DNA replication,
- a parent double-stranded DNA splits in two.
- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand
- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, option B perfectly describes semi-conservative replication of dna
Answer:
The last two points are true
Explanation:
Mutations are harmful and beneficial but can also be neutral
Mutations do cause a variation of given poulation
The answer would be, record data . This step is crucial to an experiment because you would be able to see the results.
Answer:
The excretory system maintains homeostasis (balance of body) within the body by expelling wastes. These waste products can assist in balancing electrolytes within the body. For example, you've got an overdose intake of medicines or vitamins, the kidneys and therefore the liver work together to be ready to metabolize the surplus meds.
Explanation:
Answer:
Because Neutrophils has many other functions like
- Neutrophils are the most abundant granulocytes that makeup about 40% of white blood cells and 60% of the immune cells in the blood.
- Neutrophils are the first responders to infection, and they phagocytose bacteria into phagosomes before hydrolyzing and destroying them.
- These cells also secrete a range of proteins that have antimicrobial effects as well as tissue remodeling potential.
- Neutrophils have a short lifespan and thus destroy themselves during the degradation of foreign invaders. New neutrophils are then produced continuously in the bone marrow.
- The neutrophils of another subpopulation, cager neutrophils, perform a transport function of delivering foreign particles to the target site for the action of killer neutrophils.
Like wise Natural killer (NK) cells are effector lymphocytes of the innate immune system that control several types of tumors and microbial infections by limiting their spread and subsequent tissue damage.
