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

Answer: Skin; Brain, GSA - General Somatic Afferent

Explanation:

Whilst bushwalking, Brian begins to feel chafing sensation in his thighs. In order to perceive this chafing, neural impulses must travel in one direction – from his skin to his brain. This information would travel via GSA neurones.

The peripheral mechanoreceptors which are found on the skin and used to detect movement will detect the chafing and send it to the brain.

This information will be received by the brain through General Somatic Afferent neurons which are spread across the body and have the primary function of detecting touch and temperature.

Breeding programs and habitat preserves have been established as an effort to protect the florida panther from extinction. studi

Inessa05 [86]

The answer is ‘panthers will become extinct due to the lack of genetic diversity’. The population will enter what is referred to an extinction vortex. This is when environmental, demographic and genetic factors interact and reinforce each other in a downward spiral of a species. The lack of genetic diversity in the population causes inbreeding and lack of diversity on which natural selection can act upon for the population to adapt.
