Which statement is not true about prokaryotic cells? They are always single-celled organisms, and they never contain mitochondri

a. They have a circular loop of DNA instead of multiple linear DNA molecules. They lack a nucleus, but they do have ribosomes. They may have flagella, but they never have cilia. They all have a rigid cell wall instead of a plasma membrane.

Answer:

They lack a nucleus, but they do have ribosomes.

Explanation:

Prokaryotes are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus, but, instead, generally have a single chromosome: a piece of circular, double-stranded DNA located in an area of the cell called the nucleoid.

jarptica [38.1K]

Answer:

Acinous secretory pancreatic cells.

Explanation:

Secretory pancreatic cells are organized in sac-shape structures called acini. These structures are conformed of acinous cells and center-acinous cells that secrete digestive enzymes into the intestine

Acinous cells are secretory pyramidal-shaped cells with a rouned and basal nucleus. Their cytoplasm is basophil and shows a high endoplasmic reticulum activity, as it is in charge of synthesizing the secretory enzymes.

Center-acinous cells collect secretions from acinous cells and conform ducts to where they vert all these secretions destined to be released into the intestine.

rjkz [21]

Answer:

a) Most alcohol is metabolized in the small intestine.

b) Food in the stomach slows the absorption of alcohol.

c) Alcohol inhibits the release of anti diuretic hormone, which can lead to dehydration.

Explanation:

About 80 % of alcohol is absorbed by the stomach while 20 % of alcohol is absorbed by stomach. Food materials such as lipids etc slow down alcohol absorption by the intestine because the valve that is present between stomach and small intestine is closed if food is present in the stomach. Alcohol decreases the release of anti diuretic hormone, so low water is removed from the body and reduce dehydration.

Alex17521 [72]

Answer:

Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.

Explanation:

Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.

Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.

Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
