Answer:

The cell structures which can be found in every cell are

DNA

Cytoplasm

The Cell Membrane

Ribosomes

Explanation:

The cell structures which are common to every cell whether prokaryotic or eukaryotic are

Deoxyribonucleic acid (DNA): DNA can be referred as the basic hereditary material for all organisms. In prokaryotes, DNA is not membrane bound whereas in eukaryotes the nucleus is membrane bound.

The Cell Membrane: The cell membrane comprises of phospholipid bi layers and other proteins. Cell membrane seperates the cell from the outer environment. It also acts as a barrier for imorting and exporting of materials inside and outside of cell.

Ribosomes: Ribosomes can easily be described as the protein synthesis factory.

Cytoplasm: The fluid material present inside the cell membrane which comprises of all the organelles.

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

A haploid cell formed in the male seminiferous tubules

The reproductive tissues of male and female humans develop similarly in utero until a low level of the hormone testosterone is released from male gonads. Testosterone causes the undeveloped tissues to differentiate into male sexual organs. Primitive gonads become testes; other tissues produce a penis and scrotum in males.
