Answer:
Organic compounds→ nucleotides→ RNA→ universal code.
Organic compounds are the compounds made by living organisms with at least one molecule of carbon linked to different elements like hydrogen, oxygen, or nitrogen.for example: nucleotides.
A nucleotide is the monomer units of nucleic acids- DNA and RNA. Each nucleotide is made up of organic compounds- sugar, a phosphate molecule and nitrogenous bases (adenine, guanine, cytosine, thymine and uracil).
The arrangement of nitrogenous bases in DNA decides the fate of proteins as the sequence of these bases acts as code arranged in the triplet called "codons" which code for specific amino acids.
Thus, Organic compounds→ nucleotides→ RNA→ universal code is the correct answer.
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
Land takes up mass and so does the water
Biological Weathering<span>Biological weathering would include the effect of animals and plants on the landscape. This is more than roots digging in and wedging rocks. Biological weathering is the actual molecular breakdown of minerals. There are things called </span>lichens<span> (combinations of fungi and algae) which live on rocks. Lichens slowly eat away at the surface of rocks. The amount of biological activity that breaks down minerals depends on how much life is in that area. You might find more activities like lichens near oceans where the air is humid and cooler. </span>
