Answer:

3. Rocks erode and sediment is deposited.

4. No sediment is deposited over a long time.

Explanation:

An unconfomity is a break in stratigraphic record of a place usually as a result of non-deposition or erosion.

In a sequence of sedimentary rock strata some surfaces called unconformity surfaces gives clues about the depositional history of a particular place. During an unconfomity, there is usually no sediment deposition and when deposition resumes, the underlying rocks and the new ones will not share the same attribute especially by age. Unconformity can also be as a result of erosion of a sequence.

In the case of non- conformity, a sedimentary rock is deposited above an igneous or sedimentary rock. Option 5 is a simple example of an igneous intrusion called a sill. It is not unconformity.

2a) Which of the following statements about pyruvate oxidation IS TRUE?
Darina [25.2K]

The true statements are:

  • Substrate level phosphorylation ocvurs during Pyruvate oxidation
  • 32 ATP molecules can be made by cellular respiration but only 2 ATP molecules when oxygen is lacking
  • Electrons move from protein to protein due to increasing electronegativity in the electron transport chain
  • ADP is phosphorylated in the matrix of the mitochondria during oxidative phosphorylation
  • ATP inhibits pyruvate dehydrogenase by feedback inhibition

<h3>What is glucose oxidation?</h3>

Glucose oxidation refers to the process in the cells in which glucose molecules are oxidized to form ATP and carbon dioxide in the presence of oxygen.

The first stage of glucose oxidation is the conversion to pyruvate.

Pyruvate is oxidized to acetylCoA.

AcetylCoA enters the citric acid cycle to produce reducing equivalents, NADH for the electron transport chain.

  • The true statements about pyruvate oxidation is that there is substrate level phosphorylation during the process
  • When there is sufficient oxygen, 36 ATP molecules can be made (theoretically) by cellular respiration. However, when oxygen is lacking, only 2 ATP molecules are made.
  • In the electron transport chain of cellular respiration, electrons move from protein to protein due to increasing electronegativity
  • During oxidative phosphorylation, ADP is phosphorylated in the matrix of the mitochondria
  • Aerobic respiration can be regulated by feedback inhibition of pyruvate dehydrogenase by ATP.
