Answer:
The fact is Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan. Human cells do not make or need peptidoglycan. This peptidoglycan is the target for Penicillin. It prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us as we don't possess peptidoglycan.

Answer:
The dominant gene will be expressed
Explanation:
Recessive genes are only expressed when you have two recessive genes and no dominant.
Answer:
XDxd
Explanation:
the recessive allele for the disease is represented by (d).
the dominant allele for not having the disease is represented by (D)
in order to not be affected, we know that the mother must have one uppercase D, so the last option is wrong. And in order to pass it on to her child, she needs one lower case d (to give to the child). So the second answer is correct. good luck :).
Answer: Frictional Force
Explanation: Friction always acts to oppose any relative motion between surfaces. For the simple example of a book resting on a flat table, the frictional force is zero.
