Answer:
C) Water will move out of the cell.
Explanation:
In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.
This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.
Answer;
The above statement is true
Explanation;
-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. (PCR) is a technique used to take a piece of DNA and make many copies of it. they can enlarge the genes to a size measurable to eye to get a closer glimpse of the gentics or dna strands.
