Answer:Eukaryotes only (A) and (D), bacteria only (E) both (B) and (C).
Explanation:
(A) Only eukaryotes have a nucleus.
(B) Both replicate the DNA before performing cell division, so each cell keeps a copy.
(C) This structural feature is called centromere in eukaryotes and in bacteria this role is played by the origin of replication.
(D) Centromeres are eukaryotes exclusive.
(E) Only bacteria have a replication origin.
No, cells are very complex. They are composed of highly specialized organelles that each have different functions.
Answer:
Hypertonic blood draws water out of the interstitial fluid, which makes the interstitial fluid hypertonic. This, in turn, draws water out of the cells.
Basically an hype tonic blood has high solute potential,( low water potential) compare with the surrounding plasma and the interstitial fluid. Thus the interstitial fluid is hypotonic to the blood.
Consequently,water with higher potential moves from the interstitial fluid medium into the blood by osmosis through the capillary endothelial. This raises the water potential of the blood, lowering the solute potential, thus making it hypotonic to the interstitial fluid; which is now hypertonic(lower water potential ,due to loss to the blood by osmosis).
Since the interstitial fluids is now hyper tonic to the surrounding cells, water moves from the hypo tonic surrounding cells through osmosis into the interstitial fluids. The sequence continues until a stable internal environment is achieved,
Answer:
Endosymbiosis of an oxygen-using scavenger bacterium in a larger host cell−the endosymbiont evolved into lysosomes.
Explanation:
The evolution of eukaryotic cells in all probability included: endosymbiosis of an oxygen-utilizing bacterium in a bigger host cell−the endosymbiont developed into mitochondria. development of an endomembrane framework and consequent advancement of mitochondria from a segment of the Golgi. endosymbiosis of an oxygen-utilizing photosynthetic bacterium in a bigger host cell−the endosymbiont advanced into mitochondria. endosymbiosis of an oxygen-utilizing scrounger bacterium in a bigger host cell−the endosymbiont developed into lysosomes.
Diverticula Are Tiny Herniations Of The Mucosa Through The Colon Walls, A Condition Named Diverticulosis. They Are Believed To Form When The Diet Lacks Bulk And The Volume Of Residue In The Colon Is Small. The Colon Narrows Contractions Of Its Circular Muscles And They Become More Potent, Increasing The Pressure On Its Walls. Diverticulitis Is A Condition In Which The Diverticula Become Inflamed. Mrs. Ironfield Has Diverticulitis Due To The Inflammation Of Her Diverticula, As Shown By The Pain And Mass.
