Answer:
Amino acids and Proteins
Explanation:
Plants as well as other living organisms require certain nutrients for their growth and development. One major inorganic nutrient that is needed by plants is NITROGEN, obtained in its compound form called nitrates. Nitrogen is necessary component for building amino acids and proteins in the cell because nitrogen is an integral element in the structure of AMINO ACIDS. Nitrogen makes up the amine functional group of amino acids (NH2).
Hence, If there were no nitrogen compounds in the soil, the most immediate effect on plants growing in that soil would be difficulty in synthesizing AMINO ACIDS and subsequently PROTEINS.
Answer:
Ionizing radiation.
Explanation:
Mutation is the sudden change that is occur by exposing cells to the ionized radiation which change the genetic makeup of the cell. Due to mutation, the cell does not perform its normal function like before the mutation so when the mutation occurs in the cell, the genetic or DNA makeup is changed which make the environment unfavorable for the HIV virus and the virus can not cause any infection in the cell.
I think its the cell membrane.
