Answer:

option (4)

Explanation:

According to the stratigraphic law of superposition, the layers of rocks that are at the base are the oldest rocks and those that are at the top are considered to be the youngest rock. This law enables the geologists to determine the age of the rock beds.

Considering the rock layer that is deposited at the bottom be A, followed by the next rock sequences B, C and D respectively, it can be concluded that rock layer A that is present at the bottom is the oldest rock and the rock layer D that is at the apex is the youngest rock.

Thus, the correct order from oldest to the youngest rock is A, B, C and D.

Hence, the correct answer is option (4).

You are operating a powerboat at night. Your red sidelight must be visible to boats approaching from which direction(s)?
Degger [83]
I believe the answer is head-on and port (left). The side lights are usually visible to vessels approaching from the front or the side. The red light usually indicates a vessel's port (left) side while the green light indicates a vessel's starboard (right) side. These lights ensure that there is safety at night as the vessels navigate.

Crazy boy [7]

Answer:

The factors which remained constant are as follows -

  1. material used as the membrane
  2. amount of substances used
  3. number of trials

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)
  2. whether the molecules diffused through the membrane (tubing)

Explanation

Some factors with in the experiments remained constant from the point of starting of the experiment to its end. While some factors were varied to study its impact on the experiment rate of progression or on the final product formed. Thus , out of the following given factors, the ones that remained constant are -

  1. material used as the membrane
  2. amount of substances used
  3. number of trials

The factors which have shown variation are as follows -

  1. molecule size (large starch molecules vs. small glucose molecules)
  2. whether the molecules diffused through the membrane (tubing)

Rasek [7]

Answer:

The correct answer that best fits the result of my investigation is Thermoregulation energy cannot be created or destroyed,it can only be transformed .Therefore if ATP is not generated from glucose and the energy is transformed into heat.

Explanation:

DNP or dinitrophenol act as uncoupler of oxidative phosphorylation when means it prevents the coupling of electron transport chain to oxidative phosphorylation.As a result electron transport occurs resulting in the generation of energy but the so formed energy is utilized to generate rather than ATP formation.
