Answer: '' any of the answers are correct'' . In cells, genes are segments of DNA that code for proteins; not sugars or complex carbohydrates, or lipids, but proteins. The code in the sequence of nucleotides in a gene specifies the sequence of nucleotides in messenger RNA which in turn specifies the sequence of amino acids in a protein. The sequence is variable because of mutations which can change the sequence of amino acids in the protein coded for by that gene. Therefore, in evolution, a change in a single code for a single amino acid may have an effect on individual survival. Proteins carry out many functions in a cell such as any of the answers are correct. ♡ hope this helps ♡.
<span>The answer is D) atmosphere. There are four spheres of the Earth: 1. Lithosphere (from Greek word 'lithos' = rock), 2. Hydrosphere (from Greek word 'hydros' = water), 3. Biosphere (from Greek word 'bios' = life), and 4. Atmosphere (from Greek word 'atmos' = air). Condensation is the change of water vapour into the water, i.e. the change of water from its gaseous form into liquid form. Since water vapour is the part of air, condensation occur in the atmosphere.</span>
