Help? You are studying an outcrop where the lower layer is limestone and the layer directly on top of the limestone is sandstone
ELEN [110]

Answer:

Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.

Explanation:

The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.

Explain why glucose consumption must increase in hypoxic tissues to provide the same amount of ATP that could be produced from g
slega [8]

Answer: B. In hypoxic tissues, in contrast to normoxic tissues, ATP is additionally consumed to transform lactate to pyruvate

Explanation:

In hypoxic tissues such as new cancerous cells, the vascular system is still underdeveloped, thus oxygen supply is reduced. To meet energy need, additional glucose is needed to convert lactate (result of anaerobic glycolysis) to pyruvate which can then go into the TCA cycle to yield energy. This phenomenon is very common in muscle tissues during exercise.
