In which of the following environments would you NOT expect to find fossils? (2 points)

1 answer:

7 0

You would generally not be able to recover fossils from volcanic or plutonic rock, so looking around in an area on active volcanic islands would yield nothing.

You always want to look in the layers of sedimentary rock for fossils. The Grand Canyon would be a great place to see these layers as well as a shallow ocean because you may find the remains of prehistoric shark teeth or bones protruding through the surface of the sand.

The answer is Active volcanic islands.

If this is a question in which you can choose more than one answer it may be smart to also choose a shallow ocean as well. This is because it is difficult to get the tools and materials necessary down in the water and would be difficult to get deep enough underneath sand to start digging into actual fossil bearing rock.

So in that case, the answer would then be both Active volcanic islands and A shallow ocean.

What are DRIs and why are they preferred? Why are they not on food labels?

Pie

DRIs is the general term for a set of reference values or guidelines that are used to plan and asses nutrient intakes of healthy people. These values which vary by age and gender include:

- Recommended Dietary allowance (RDA): average daily level of intake sufficient to meet nutrient requirements of about 97 - 98% of healthy people.

-Adequate intake (AI): established when evidence is not sufficient to develop an RDA and is set at a level assumed to ensure nutritional adequacy.

- Tolerable Upper Intake (UL): Maximum daily intake unlikely to cause adverse health effects.

DRIs are not necessarily found on labels because there is no law requiring that they must be placed there.

7. During osmosis A) Pure solvent diffuses through a membrane, but solutes do not. B) Pure solutes diffuse through a membrane, b

MrRissso [65]

Answer: Option A.

Pure solvent diffused through a membrane but solutes do not.

Explanation:

Osmosis is process where solvents or molecules move from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane which tend to balance the concentration of solutes. Osmosis is passive transport i.e it does not require energy for movement.

Which of the following sequences is correct for the downhill movement of electrons during cellular respiration? A. glucose – cit

Volgvan

Answer:

B. glucose – NADH – electron transport – O2

Explanation:

This is the sequence from glycolysis in which glucose molecules are split down to pyruvate, to oxidative phosphorylation.

During this process the electrons are released from glucose molecule as it is oxidised multiple times as pyruvate, and other molecules formed subsequently in Kreb's cycle, until the oxidative phosphorylation is reached .

The makes the carrier molecules to be reduced.Thus NAD→NADH,FAD→FADH .

The electrons from above are transferred in hydrogen atoms to matrix by these co-enzymes.Where the H is split to electrons and protons.

The electrons for the ETC, produce the PMF for transporting protons into the intramembrane space.

The concentration of protons generated the electrochemical gradients which is needed to produce energy for for phosphorylation of ADP with Pi to form ATP by ATpase synthase.

The electrons moves as chain,and this is finally accepted by oxygen as the final electron acceptor.
