Biology

Answer:

DNA fragments are negatively charged, so they move towards the positive electrode. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.

Under what circumstances would a species of meat eating animals be most likely to evolve to eat plants
zloy xaker [14]

Answer:

Any insect unlucky enough to land on the mouth-like leaves of an Australian pitcher plant will meet a grisly end. The plant's prey is drawn into a vessel-like ‘pitcher’ organ where a specialized cocktail of enzymes digests the victim.

Now, by studying the pitcher plant's genome—and comparing its insect-eating fluids to those of other carnivorous plants—researchers have found that meat-eating plants the world over have hit on the same deadly molecular recipe, even though they are separated by millions of years of evolution.

The (matrix / stoma / cytoplasm / nucleolus) is the innermost compartment of a (cytoplasm / cell wall / mitochondrion / nucleus)
Olin [163]

Answer:

Matrix, Mitochondrion, Kreb's cycle, Pyruvic acid

Explanation:

The above question illustrates aerobic cellular respiration, specifically the second stage called Kreb's cycle or Citric acid cycle. This process occurs in the inner membrane of the mitochondrion of eukaryotic cells called MATRIX.

It occurs when the pyruvic acid produced during Glycolysis (first stage of cellular respiration that occurs in the cytoplasm) is converted to Acetyl CoA in order to enter the citric acid cycle in the mitochondrion. The Acetyl CoA is then used in a series of reactions that comprises of reduction-oxidation, hydration, dehydration, and decarboxylation.

This reactions involving 8 steps converts the Acetyl CoA (from pyruvic acid) to 2 molecules of CO2, 1 molecule of GTP/ATP, and electron donors NADH2 and FADH2.

Three-carbon molecules of PGA are converted to G3P small sugar molecules by _____, which come from the light reaction. ADP and N
True [87]

Answer:

ATP and NADPH

Explanation:

The second stage of the Calvin cycle is the reduction in which 3-Phosphoglycerate is reduced into Glyceraldehyde 3-phosphate by a series of reactions. These reactions consume ATP as an energy source and NADPH as an electron donor. ATP and NADPH for produced during the light-dependent phase of photosynthesis. Transfer of electron through ETC generates proton concentration gradient across the thylakoid membrane which in turn drives ATP synthesis. Electrons released from water splitting finally reach NADP reductase enzyme that reduces NADH into NADPH.
