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.
Answer:
A homozygous recessive pea plant would have genotype rr and the heterozygous plant would have genotype Rr. So after the crossing between these two individuals occurs the two offspring produced would be heterozygous and the other two would be homozygous recessive.
R r
r Rr rr
r Rr rr
Therefore the genotype ratio would be 1:1 and the phenotypic ratio would also be 1:1 in the F1 generation because half would be round and half would be wrinkled.
Elements are made from one type of matter.
Answer:
"D" is the option that best answers the question
Explanation:
Nutrient-rich blood flows into the liver from the intestines through the hepatic portal vein.
Its primary function is to help with absorption to bring nutrient- and toxin-rich blood to the liver for processing.
The answer would be Biology and Chemistry. Although they do use a little bit of physics, it's mostly chemistry and biology.
