<span>Cytosis requires energy, and the production of energy depends on oxygen. Diffusion does not require energy.</span>
The tissue you are referring to here is the xylem, a <u>vascular tissue</u>, whose basic function is to transport water and nutrients from the roots to the rest of the plant.
when no oxygen is present, there is no electron acceptor, thus pyruvate goes through a process known as fermentation which usually forms lactic acid or ethanol as a by-product. During lactic acid fermentation, pyruvate is reduced directly by NADH to form lactate as a waste product, with no release of CO2.
Your answer is A Good sir questions
Answer:
The correct answer is E. Answer choices a, b, and c.
Explanation:
There can be many causes for a gram standard culture to appear red like if we use decolorizer for a long time then even the gram-positive cells present in the culture will lose their dye and become decolorized. Then they appear red after counterstaining with safranin.
If a gram-positive culture is older than 24 hours they can appear red because after 24 hours because the peptidoglycan starts degenerating and fails to persist crystal violet it their walls.
Iodine makes complex with crystal violet which is retained by peptidoglycan present in gram-positive cell wall. So when we forgot to add iodine crystal violet will not be retained and cells will appear pink.
Thus, the correct answer is E. Answer choices a, b, and c.
