Biology
1 answer:
olya-2409 [2.1K]3 years ago
5 0

The correct answers are:

• Liver cells are abundant in SER.  

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.  

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.

A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

45.7 * 32.5 = P_{2} * 4.1

1485.25 = 4.1P_{2}

P_{2} = \frac {1485.25}{4.1}

P_{2} = 362.26

Final pressure, P2 = 362.26 kPa
