What does a single-celled prokaryote, like a bacteria, have in common with a single-celled eukaryote, like an amoeba? Select the correct answer.

Both are single-celled microorganisms which contains plasma membranes, cytoplasm, ribosomes, DNA

Explanation:

Cells are the smallest functional unit of organisms which are classified under two main categories namely:

--> prokaryotic cells and

--> eukaryotic cells.

Prokaryotes are unicellular or single-celled organisms which do not possess true nuclei. Their cell structure is simple as there is NO definite nucleus and the chromosomes lie free in a particular part of the cell. Examples of organisms that belongs to this group are the bacteria. They can only be seen through a high power of a light microscope and are found in air, water, soil and living organisms. The general structure of prokaryotes like bacteria contains Chromosome ( single DNA strand coiled up), cytoplasm, ribosome which are few cell components among others.

Eukaryotes are organisms which possess a definite or true nuclei. The cell structure is complex and highly organized with a well-defined nucleus (meaning its DNA is surrounded by a membrane). Many structures called the cell organelles are present which include: mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes with other cell components, that is the cytoplasm, plasma membrane and ribosomes. Each organelle carries out a certain type of work. Examples of organisms that belongs to this group are the amoebas.

From the explanation above, both bacteria and amoeba are single- celled organisms which contains plasma membranes, cytoplasm, ribosomes, and DNA.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
