Explanation

To find the fraction of green marbles, we need to calculate the total number of marbles first.

Sara has:

- 5 red marbles

- 3 green marbles

- 2 blue marbles

Total marbles = 5 (red) + 3 (green) + 2 (blue) = 10 marbles

Next, we determine the fraction of green marbles out of the total marbles:

Fraction of green marbles = Number of green marbles / Total number of marbles

Fraction of green marbles = 3 / 10

Explanation

The use of transgenic farm animals to produce pharmaceuticals is commonly referred to as Gene pharming.

Gene pharming involves the genetic modification of farm animals to produce specific pharmaceutical products, such as:

• proteins or antibodies
• in their milk
• blood 
• other bodily fluids

Explanation

The carbon-carbon (C-C) bond length in benzene is 1.39 Å (angstroms).

This bond length is intermediate between a single bond (typically around 1.54 Å) and a double bond (typically around 1.34 Å) due to the resonance structure of benzene

Where the electrons are delocalized over the six carbon atoms.

This delocalization results in a uniform bond length throughout the benzene ring.

Explanation

Gallstones, mainly cholesterol gallstone formation, result from several physiological events such as:

• hepatic secretion of bile saturated with cholesterol
• nucleation of cholesterol monohydrate crystals in the gall bladder
• impaired emptying of gall bladder contents.

Explanation

Explanation

Cement does typically contain a small percentage of gypsum.

Gypsum (calcium sulfate dihydrate, (CaSO4 ⋅ 2H2O) is added to cement primarily to regulate the setting time.

The percentage of gypsum in cement is usually around 2-5%.

It prevents the cement from setting too quickly by controlling the rate at which the cement hydrates and hardens. 

Explanation

Thus, the First law of thermodynamics furnishes the relationship between:

• heat
• work
• the internal energy of the system

Explanation

The angle through which plane-polarized light is rotated by a reacting mixture is measured by the optical rotation method.

Optical rotation, also known as optical activity, is a property exhibited by certain substances

That causes them to rotate the plane of polarized light passing through them

This rotation is quantified by measuring the angle of rotation, typically using a polarimeter
