Penicillins disrupts bacterial cell wall synthesis.
<h3>
How does penicillin affect bacterial cell walls?</h3>
- Penicillin kills bacteria by inhibiting the proteins which cross-link peptidoglycans in the cell wall .
- When a bacterium divides in the presence of penicillin, it cannot fill in the “holes” left in its cell wall.
- β-Lactam antibiotics, including penicillins, cephalosporins, monobactams, and carbapenems, are distinguished by a lactam ring in their molecular structure and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls.
- Penicillins work by bursting the cell wall of bacteria. Drugs in the penicillin class work by indirectly bursting bacterial cell walls.
- They do this by acting directly on peptidoglycans, which play an essential structural role in bacterial cells.

Answer:
C. Both light tan and dark tan body color provided an advantage to the crabs on this beach, but not necessarily in other crab habitats.
Explanation:
The changes in the number of light tan and dark tan body color of crabs that occured can be described as a diversifying or disruptive selection.
This disruptive selection occurs when individuals with extreme traits on both ends of the spectrum become selected against individuals of ntermediate or medium traits.
In the case of the crab, their environment favors the selection of both extreme values as against those intermediate individuals, as both light tan and dark tan body color of the crabs gives them advantage over others in this particular environment. This may only be obtainable in this environment or similar beach environment with the same settings and conditions.
The right answer is A.
Osmosis is a phenomenon that considers only the exchanges between two liquid solutions of different concentrations in liquid phases separated by a semi-permeable wall. Osmosis is a phenomenon of diffusion of matter, demonstrated when solvent molecules pass through a semi-permeable membrane separating two solutions whose solute concentrations are different; the overall transfer of solvent is then from the least concentrated solution (hypotonic medium) to the most concentrated solution (hypertonic medium) to equilibrium (isotonic media).
The diffusion of matter, or chemical diffusion, refers to the natural tendency of a system to render uniform the chemical potential of each of the chemical species it contains.
Chemical diffusion is an irreversible transport phenomenon that tends to homogenize the composition of the medium.
A law is something that can be measured or observed to be true. A theory, is something that can be assumed to be true based on the best available knowledge.
