A quantity of a gas has an absolute pressure of 400 kPa and an absolute temperature of 110 degrees kelvin. When the temperature

VMariaS [17]

Answer: The new pressure of the gas is (A) 854.46 kPa.

The pressure of a given mass of gas at the absolute temperature 110 degrees K is 400 kPa.

The temperature is raised to 235 degrees K with constant volume.

Therefore,

Initial pressure $P_{1}=400kPa$

Initial temperature $T_{1}=110K$

Final temperature $T_{2}=235K$

Final pressure $P_{2}=?$

According to pressure law of gas,

$\frac{P_{1} }{T_{1} }=\frac{P_{2} }{T_{2} }$ ( at constant volume) $P_{2}=\frac{P_{1}T_{2} }{T_{1} }$

$P_{2}=\frac{400X235}{110}$

$P_{2}=854.46kPa$

Thus, the required new pressure of the gas is 854.46 kPa.

Which of the following is not a step in the process of natural selection

Paraphin [41]

Answer:

A step that is not part of natural selection is people select which individuals breed and which ones do not.

Explanation:

Natural selection is a process in which favorable or unfavorable environmental conditions determine the evolution of species, producing differences in their genotype over a long period of time.

As its name indicates, it is a natural selection, in which no intervention by people is contemplated, so that people cannot determine which individuals breed.

Natural selection implies that the characteristics on which the environment influences are inheritable, that there is genetic variability in the population and that the variability of these characteristics implies the ease of reproduction and survival capacity.

The other options do form part of natural selection, since they are based on the three premises of this process:

Inheritable characteristics.
Genetic variability.
The variability of characteristics influences reproduction and survival.

The act of breathing raises the blood oxygen level, lowers the blood carbon dioxide concentration, and raises the blood pH. Acco

tino4ka555 [31]

Answer:

A rise in blood carbon dioxide concentration.

Explanation:

The feedback regulation may be defined as the process in which the end product of the metabolic pathway regulates the homeostasis of the body. Two main types of feedback are positive feedback and negative feedback.

The negative feedback mechanism occurs when the end product of the reaction is responsible for the shutdown of the metabolic pathway and decreases its concentration. The breathing is controlled by the negative feedback mechanisms, the increase in carbon dioxide concentration acts as the negative sensor as this sensor is mainly responsible for the increase in amount of oxygen level and maintain homeostasis of the body.

Thus, the correct answer is option (c).
