The pressure that is exerted by one gas as if it occupied a container by itself best defines partial pressure in a mixture of gases. Therefore, option B is correct.
Partial pressure is defined as the pressure exerted by each gas in a container filled with more than one gas. The pressure of any gas contained within the container is referred to as its partial pressure.
The concept of partial pressure is derived from the fact that each specific gas contributes a portion of total pressure, which portion is the partial pressure of that gas. It's almost like using a percentage or fraction of the total to describe all the parts.
A gas's partial pressure is a measure of the thermodynamic activity of its molecules. Gases dissolve, diffuse, and react in gas mixtures and liquids based on their partial pressures, not their concentrations.
Thus, option B is correct.

Answer: Lysosomes
Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.
-15 =5m/7 find m
Answer:
m= −21
Explanation:
Solve for m by simplifying both sides of the equation, then isolating the variable. m=−21
in the biosphere
in the geosphere
in the hydrosphere
Answer:
The correc answer is C. greenhouse gases.
Explanation:
The atmosphere is a layer of gases that surrounds our planet and is one of the essential elements for life on it.
The atmosphere protects us from harmful solar radiation from the Sun. The Sun, in addition to light and heat (infrared radiation), emits other radiation such as gamma rays, X-rays and ultraviolet rays that are harmful to life. These harmful radiations are absorbed by the atmosphere.
The atmosphere also protects us from the impacts of meteorites. These are from outer space are attracted by gravity and fall on the earth's surface. Upon coming into contact with the gases of the atmosphere, at high speed, the friction causes them to heat up so much that they become incandescent and end up disintegrating, avoiding reaching the ground. Only the largest (rare) can pass through the atmosphere and reach the ground.
Something similar happens that with meteorites occurs with the dangerous particles of space.
Greenhouse gases contribute, to a greater or lesser extent, to the increase of the greenhouse effect, since they are capable of absorbing the heat energy carried by long-wave radiations that are reflected by the Earth's surface.This phenomenon prevents the solar energy constantly received by the Earth from returning immediately to space and causing the temperature of the air near the ground to rise. Then there are changes in the climate such as sea level rise, changes in rainfall, disappearance of forests, extinction of organisms and problems for agriculture.
So the correc answer is C. greenhouse gases.
