Scorpion4ik [409]

Answer:

The culture might not be stained properly or the culture might be too old.

Explanation:

Gram staining is done to differentiate between gram-positive and gram-negative bacteria according to the difference in their cell wall. In gram staining, the gram-positive bacteria appears violet and gram-negative bacteria appear pink in color.

Therefore if a pure culture contains have both red and purple cocci that it can be concluded that the gram stating was not done properly like too much destaining was done or too much safranin was used or maybe the culture is too old so that cell wall of some bacteria degrades.

ANTONII [103]
The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span>  </span>

n200080 [17]

Answer:

answer should be "making water hypoxic for organisms". reason is because the runoff from these treatment plants are filled with nutrients, which will cause eutrophication. eutrophication is excessive algae sprouts which create more DO but then later becomes all used up when they decompose, making it so other organisms have no oxygen.

The Venn diagram compares and contrasts meiosis and mitosis. If you were to add to the Venn diagram, which description would not
Rasek [7]

Answer:

<em>C) diploid daughter cells</em>

Explanation:

Meiosis can be described as a process of cell division in which the chromosome number is reduced to half of that of the parents. Four daughter cells are produced as a result of meiosis and these cells are haploid. Hence, option C, diploid daughter cells will not apply to meiosis.

Mitosis can be described as a process of cell division in which two new daughter cells are produced which are identical to the parent cells. The daughter cells are diploid. Hence, this description would be applied to mitosis.
