Bacitracin blocks the transport of nag and nam across the cytoplasmic membrane to the cell wall. Like other antimicrobials that block cell wall synthesis, this would result in weak cell walls and cell lysis. Antimicrobilas that act by inhibiting cell wall synthesis include beta-lactams, vancomycin and cycloserine and isoniazid and ethambutol among others. They prevent bacteria from increasing amount of peptidoglycan, they have no effect on existing peptodoglycan layer and therefore are effective only for growing cells.
Answer:
When a potato chip is put into salt water, the potato cells become flaccid (soft and floppy). This is because there is a higher concentration of water molecules inside the potato cells than outside. If more water enters the cell, it becomes turgid. This is important in supporting plants.
The answer is through facilitated diffusion. It is then called as the transport of substances in a biological membrane from a higher concentration to a lower concentration area though carrier proteins. Hope this is the right answer and would be of help.

Answer: Option D
Explanation:
The control of the non-crop vegetation is necessary in order to maintain the fertility of the soil.
The non crop vegetation should be cut in order to maintain the availability of the nutrients, water for the crop vegetation.
Example: The plant named eucalyptus has its roots deep inside the ground. So there is no other plant grown along with this plant because it will not get enough water for its growth.
Likewise the non crop vegetation should be stopped from growing to maintain the ecological balance.
