Answer:
The features of prokaryotes include circular DNA molecules and small ribosomes.
Explanation:
Prokaryotes are organisms having only one cell (unicellular). In their cells, an organized nucleus is absent along with other membrane-bound organelles. Examples include bacteria and archaea. The prokaryotic cell mainly consists of the plasma membrane, cytoplasm, DNA and ribosomes. Some prokaryotes have special structures such as flagella, pili, fimbriae, etc. Flagella help in the locomotion and pili or fimbriae are used for the attachment to host cells and other surfaces.
Their cells contain large quantities of genetic material (DNA and RNA). A single, large circular strand of DNA is found in the central part of the cell (nucleoid) and contains most of the genes. The ribosomes found in prokaryotes are smaller in size. A large number of ribosomes are present inside a prokaryotic cell. The shape and composition of ribosomes are slightly different than those in eukaryotic cells.
The correct answer is <span>the contribution an individual makes to the gene pool of the next generation relative to the contribution of another individual.
Each individual in a population has an absolute fitness which is a measure of the successfulness of an individual in reproducing and leaving viable offspring. The relative fitness, on the other hand, is the relative fitness of the individual compared with another individual, usually the one with the highest fitness. </span>
Explanation:
Body cells make up the body of any multicellular organism. A body cell contains a complete number of chromosomes and is called a diploid cell while a gamete contains only half the number of chromosomes of its parent cell, and it is called a haploid cell.
Hope it's R8
<span>Compare: both RNA and DNA have 3 nitrogenous bases: Adenine Cytosine and Guanine. Also b</span>oth have a phosphate groups in their nucleotides<span>
Contrast: </span>RNA is a polymer with a ribose AND a phosphate backbone. It has four different nitrogenous bases: adenine, guanine, cytosine, and uracil.
DNA<span> is a long polymer with deoxyriboses AND phosphate backbone. It also has four </span>different<span> nitrogenous bases: adenine, guanine, cytosine and thymine.

Hope this helps
