bixtya [17]3 years ago
6 0

Velocity is the speed of an object moving in a definite direction. The velocity of an object can be uniform or variable. When an object moving along a straight line at variable speed, we can Express the magnitude of its rate of motion in terms of average velocity.

Average velocity=Initial velocity+Final velocity/2

The SI unit of velocity is m/s.

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

How can insulin deficiency lead to an increase in blood glucose concentration?
MakcuM [25]

When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.

Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis  ie increased gluconeogenesis .

With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.

The substance used to separate the proteins from the dna
Genrish500 [490]

DNA is deoxyribonucleic acid, which is insoluble in ethanol. In the process of centrifugation the addition of ethanol can aid to separate protein from its DNA.

<h3>What is centrifugation?</h3>

Centrifugation is a process of separating different molecules in a given sample that have different densities by rotating them in solution around an axis at high speed.

It is the frequently applied techniques in the molecular biology laboratory.

The addition of alcohol or ethanol to the sample followed by centrifugation can separate the proteins from its DNA.

Thus, the substance used to separate the proteins from the DNA is alcohol or ethanol.
