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:
As the variables are not given, let us help with general explanation on manipulated variable.
Explanation:
A manipulated variable is an independent variable. In a scientific experiment, an independent variable can be described as a variable which can change naturally or which is changed by the researcher to check its effect on the dependent variable. The dependent variable is the variable which is under study and being tested.
For example, to check the difference in photosynthesis rate by light, the amount of light will be the independent variable and the rate of photosynthesis will be the dependent variable.
Answer:
No.As we know that phenotype depends on physical appearance whereas genotype is genetical materials. So person having same phenotype doesn't mean they have same genotype.
Some advances is that organelles, cells, and the difference between the cells of a plant and a cell of an animal. This was an advance because not only did we discover new things but we learned how or body functions with them and how they work. Hopefully you got what you were looking for. :)
