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.
Any theory can be disproven. A theory is simply a hypothesis that has been accepted as generally true, however in the realm of science, anything can be disproven.
<span>1) Receptors are linked with sensory neurons that send any signals that the receptors pick up to the brain. If the signal requires some kind of response to maintain homeostasis, signals travel through motor neurons to effectors.</span>
<span>2) The organ that controls the regulation of body temperature is the hypothalamus while the process that allows us to maintain our core temperature is referred as thermoregulation.</span>
3) Controlling blood sugar levels with insulin is a negative feedback mechanism. Receptors in the body sense when blood sugar levels rise. To deal with that, the pancreas pumps insulin into the blood to lower it. Blood clotting is a positive feedback mechanism where platelets start to clump around an injury in a blood vessel and release chemicals that bring more platelets that end up doing the same thing to form a clot.
