Answer:
d. mechanical isolation
Explanation:
Mechanical isolation is a prezygotic barrier in which there is a physical barrier that prevents two populations of a species from mating successfully as a result of morphological differences.
This reproductive isolation can be seen in the Euhadra species of Japanese land snail, where snails with right hand shells and left hand shells are unable to physically corpulate successfully.
Only eukaryotic cells contain membrane bound organelles (such as a nucleus). Prokaryotic cells do not. Therefore, the answer is A.
Answer:
No, proteins don't carry out translation, ribosomes do.
And even if one considered the fact that ribosomes contain proteins (even though it is the ribosomal RNA part that links amino acids together in translation), it still would not be true that the variations in base sequence required more ribosomal proteins.
Explanation:
hope this helps
its the only way i could explain it sorry
Answer:
Una vibración se puede caracterizar por su frecuencia y su intensidad. La frecuencia es el número de veces que se completa un ciclo de oscilación y se mide en hercios (Hz). Un hercio equivale a un ciclo por segundo.

Answer:
Plastic and trash bags can be used to generate renewable energy in the following way the mechanism of cold plasma pyrolysis.
Explanation:
- Cold plasma pyrolysis is a method in which chemical compounds like plastic wastes and trash bags are subjected to high temperatures like 400 to 650 degree Celsius under limited oxygen condition.
- The above process generates huge amount of energy in the form of heat that can be converted to usable electricity.
- The process generates compounds like hydrogen, methane and ethylene.
- The hydrogen and methane can be used as clean fuels because they produce minimum harmful components like carbon dioxide and soot on combustion.
- The ethylene is the basic component of plastics and can be reused to produce more plastics.
