Answer:
because they were originally long period comets whose orbits were perturbed by the gravity of the giant planets and directed into the inner solarsystem
Seminiferous tubles is the only part of a male reproductive system
Oceans bring warm water to distant shores. Ocean temperatures and winds are coupled into a complex interactive system. Varying ocean temperatures affect local atmospheric pressure, which creates regional wind patterns that, in turn, drive oceanic currents that affect surface ocean temperatures.
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.
Answer:
We learned in biology class that every cell in the body has the same DNA. Whether a heart cell, skin cell or muscle cell—they all read from the same genetic blueprint. Now, scientists are learning there is more to the story.
