Answer:
Amoxicillin inhibits an enzyme required to build cell walls in bacteria.
Since humans have cell membranes, they are unaffected by amoxicillin.
Explanation:
Antibiotics are specifically designed to target bacterial cells, therefore, they don't kill human cells.
Amoxicillin, a type of penicillin, inhibits the biosynthesis of bacterial cell wall. The bacterial cell wall contains peptidoglycan that constitutes almost 95% of the cell wall in some Gram positive bacteria and as little as 5-10% of the cell wall in Gram negative bacteria. Amoxicillin inhibits the cross linkage between the linear peptidoglycan polymer chains that make up a major component of the cell walls of both Gram positive and Gram negative bacteria.
Answer:
This definition suits that of "HOMOLOGOUS CHROMOSOMES"
Explanation:
Homologous chromosomes are similar pairs of chromosomes i.e. in length, gene positioning and centromere location (one from each parent) but not identical. Homologous chromosomes are not identical in the sense that, alleles on each pair may be different, resulting in genetic variation of the offspring.
Using humans as a case study, a karyotype (pictorial display of chromosomal arrangement) shows the complete set of chromosomes, which has two complete set (diploid). Each human cell contain 23 pairs of chromosomes, with each pair contributed by each parent i.e. 46 chromosomes in total. Every chromosome pair represents a set of homologous chromosome.
The answer is C Good luck
Answer:
Larva: the second, "worm-like" stage in the life cycle of insects that undergo complete metamorphosis (like caterpillars).
Explanation:
Answer:
The plant cell becomes turgid
Explanation; freshwater contains a low amount of salt concentration .when cells are placed in it,it creates an osmotic difference, as the cytoplasm of the cell would be of higher concentration than the surrounding water .as a result,water moves into the cell by osmosis.
Most Unicellular organisms has organelles such as contractile vacuole to expel excess water out of it's cell.if the animal cell is unable to expel water,it bursts.
In plants cells,the cell swells and the swelling is checked by the inflexible and rigid cell wall.
The cell wall of plants are made of cellulose, lignin and pectin.
