Why do animal cells have centriole but plant cells do not?

1 answer:

8 0

Animals have centrioles to form spindle fibers during prophase. The centriole divides cells. Plants do not have them because they have microtubules instead; they do not need centrioles. Plants are capable of forming a circular loop of microtubules around the future plane of division prior to prophase called the preprophase band, rather than centrosome. Basically- plants don't need it. They have a different way of cell division.

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

Usimov [2.4K]

Answer:

DNA polymerases from human cells will denature under these conditions.

Explanation:

Under the PCR conditions described, DNA polymerase from T. aquaticus would be more effective than DNA polymerase from human cells. This is due to the higher optimal temperature of DNA polymerase from T. aquaticus.
