Explanation

In 1787, the French scientist Jacques Charles discovered that the volume of a gas varies when we change its temperature, keeping the pressure constant.

Jacques Charles is known for Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature (in Kelvin) when pressure is held constant.

This relationship is fundamental in gas behavior studies.

Explanation

Oxidative phosphorylation is coupled with the electron transport chain (ETC).

This coupling is essential for cellular respiration and the production of ATP, the cell's main energy currency. 

Explanation

After the removal of both ovaries, the hormone that significantly decreases is estrogen. 

The ovaries are the primary source of estrogen in the female body, so when they are removed, estrogen levels drastically drop. 

Explanation

To express the number 0.000057 in scientific notation, you need to represent it as a number between 1 and 10 multiplied by a power of 10.

0.000057 can be written as:

5.7×10−55.7×10−5

In scientific notation, this means 5.7 multiplied by 10−510−5.

Explanation

Stokes' law applies to small spherical particles in viscous fluids. 

Stokes' law describes the drag force exerted on a spherical particle moving slowly through a viscous fluid.

And it is only valid for small, spherical particles moving in a laminar flow with low Reynolds numbers

Where the viscosity of the fluid plays a significant role.

Explanation

A pendulum's swing speed is inversely proportional to the strength of gravity.

Since Earth's gravity is weakest at the equator due to its centrifugal force caused by rotation, the pendulum will swing most slowly there. 

Explanation

"Whose" shows possession.

"Who's" means "who is," which doesn't fit here.

Explanation

Antigens are typically glycoproteins or lipopolysaccharides found on the surface of pathogens.

These structures are recognized by the immune system and trigger an immune response.

Explanation

Molting (also spelled moulting) is the process by which insects shed their exoskeleton to grow.

This process:

Occurs only during the immature stages (larva or nymph).

Stops once the insect becomes an adult (mature) — the adult stage does not molt.
