Answer:
The correct answer is The drug binds to the 30S small ribosomal subunit eukaryotes have 40S small sub unit.
Explanation:
Tetracycline belongs to broad spectrum antibiotic.Tetracycline is named so because it contain a derivative of four hydrocarbon rings.
Tetracycline act by inhibiting the protein synthesis process in prokatotes by binding to the small ribosomal subunit also called 30S subsunit and blocks the binding of amino acyl tRNA to the A site or attachment site of ribosome.
As eukaryotes contain 40S ribosomal subunit,it becomes difficult for tetracycline to bind with 40S ribosomal subunit of eukaryotes.
The nutrient is phosphorus
<h3>The phosphorus cycle</h3>
Phosphorus cycles between living components of the earth (biosphere) and the soil (geosphere).
The element's reservoir is mainly the sediments of the ocean and rocks. Phosphorus gets into the soil by weathering of rocks.
Plants are able to pick the element up from the soil and animals are able to get their phosphorus by consuming plants.
When plants and animal die, their body decomposes and the phosphorus in them enters the soil.
Thus, the cycle being referred to in the illustration is the phosphorus cycle.

Answer:
Both cones and rods participate in dark adaptation, slowly increasing their sensitivity to light in a dim environment. Cones adapt faster, so the first few minutes of adaptation reflect cone-mediated vision.
Basically all of the choices given are failure of negative feedback mechanisms to maintain homeostasis. The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer you were looking for and it has come to your help.
