Cell-wall inhibiting antimicrobial drugs be less effective on gram-negative bacteria compared to gram-positive bacteria because the outer membrane of the gram-negative bacteria inhibits penetration of the drug and the peptidoglycan found in gram-positive bacteria is structurally different from that in gram-negative bacteria.
Answer: Option B & C
<u>Explanation:</u>
Antimicrobial drugs are induced into a body to act on that particular selective bacterium which causes disease. When antimicrobial drugs are injected they act efficiently on the gram positive bacteria inhibiting the proliferation of the cells by acting on the cell wall so that cell multiplication doesn’t happen.
On the other hand it is hard to act on the gram-negative bacteria as it has a cell membrane that inhibits drug penetration into it. Both cell walls contain peptidoglycan but in the gram-positive is more assembled and layered while in the gram-negative it is just a thin layer. As gram-positive is thick layered it provides place for another molecule to attach to it but the thin layer in gram-negative inhibits it.
The answer is A, a mountain building.
The two faces of the book represent the tectonic plates
As he presses them towards each other he is modeling a convergent boundary, and mountains are an affect of convergent plates.
Answer:
Incomplete dominance
Explanation:
Incomplete dominance is a condition observed in the organisms while studying their genetics.
When the organisms with two alleles for the same trait are crossed, then neither of the two alleles completely express themselves but a new variation of the trait is formed.
This can be observed in the given scenario also when the ed and white flowers are crossed, then the pink flowers (a new variation of the trait) is formed called blended trait.
Thus, incomplete dominance is correct.
Prokaryotes do not contain membrane, and eukaryotes do contain membrane.
