According to the article, how does the intermittent recovery test differ from the intermittent endurance test?
The intermittent recovery test differ from the intermittent endurance test in the way that intermittent recovery test uses twenty-five meter long strip of floor space instead of twenty-two and half meter long strip.
Explanation:
In intermittent endurance test, twenty-two and half meter long strip divides the floor into two sections - one of twenty meter and another of two and half meter. The subject is supposed to run in the longer section a per CD until he reaches the other side or he hears the recorded beep.
One hearing the beep, he must turn and return back to his starting point. On reaching there, he is given five seconds time to walk or jog in the shorter section which is of two and half meter.
If the subject fails to cover twenty meter long section before beep sound, a warning is issued to him.
In case of intermittent endurance test, twenty-five meters long strip is used to divide the floor section into parts, one of one of twenty meter and another of five meter. In this test extra five seconds are also added for active break time, thus making it of ten seconds.
Answer:
The intermittent recovery test differ from the intermittent endurance test in the way that intermittent recovery test uses twenty-five meter long strip of floor space instead of twenty-two and half meter long strip.

Does a cell use energy when molecules diffuse in or out of the cell?
Why?
Answer:
There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
Explanation:
The cell use energy when molecules diffuse as there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
What is diffusion?Diffusion has been defined as the process of passive transport in which a single substance would moves from an area of high concentration to an area of low concentration until the concentration has been equal on both areas.
Diffusion distance rate of diffusion depends on the distance molecules have to travel. The greater the diffusion distance needs to travel the longer it takes to move.The greater the distance that a substance must travel, the slower the rate of diffusion. Oxygen moves from the alveolus to the capillary through the respiratory membrane which means the thickness of the respiratory membrane is diffusion distance.

What can you infer about water in the air?
Water in the air contains contaminates.
Water in the air does not have contaminates.
Water in the air is very large.
Water in the air is very salty.
Answer:
I believe water in the air contain contaminates c:
Explanation:
Heat from the Sun causes water to evaporate from the surface of lakes and oceans. This turns the liquid water into water vapor in the atmosphere. Plants, too, help water get into the atmosphere through a process called transpiration! ... Water can also get into the atmosphere from snow and ice.
Final answer:
Water in the air contains contaminants because all naturally occurring water can absorb substances from the environment. Human activities and natural phenomena both contribute to the contamination of atmospheric water vapor.
Explanation:
Based on the information provided, we can infer that water in the air does contain contaminates. All naturally occurring water, including atmospheric water vapor, can absorb various substances from the environment, such as minerals, pollutants, and biological materials. As water is a good solvent, it easily dissolves materials it comes across, leading to the presence of contaminants. While environments can handle a degree of contamination, there is a threshold beyond which the contamination becomes harmful to health and ecosystems.
Pollution happens when contaminants are introduced into the environment at damaging levels. Water vapor in the air can be contaminated by human-induced pollution, such as industrial emissions, or by natural phenomena, like volcanic eruptions. It is our human activities – agricultural, industrial, and sewage treatment processes, among others – that have a significant impact on the quality of water in the environment. This holds true for the water in the air, as it is part of the global water cycle and is subject to the same contamination processes as surface and ground water.

The energy of a UV wave from the sun becomes part of the internal energy of the sidewalk causing the sidewalk to heat up, then the wave's energy was
Answer:
The wave energy was transformed into thermal energy.
Explanation:
Thermal energy is energy related to the generation of heat within a system. This is because thermal energy arises when potential energy agitates the molecules of a system, generating kinetic energy. This agitation of the molecules promotes heat to the system, transforming the kinetic energy into thermal energy and making the system temperature higher.
An example of this can be seen when the waves coming from solar energy promote the heating of a system, like a sidewalk for example. These waves promote the movement of the sidewalk molecules, transforming the wave energy into thermal energy.

A cows grazing in the field. Under what conditions does the cow have relative motion
Relative motion has been defined as the motion or the velocity of the object in reference to the start point. The cow will have relative motion if it changes its position compared to the reference.
What is relative motion?Relative motion or relative velocity has been the velocity and motion of the object with reference to the initial point and to the other body. It defines the rate of change occurring in two different bodies at the same time.
It can be used to show the relative motion of the cow as a reference point or frame is taken as the point to which the motion or the velocity of the cow is taken into consideration. The field is the fixed point to which the cows show motion.
Therefore, the relative motion of the cow can be explained based on the reference point of the field.

Relative motion between the cow and its surroundings occurs when either the cow is moving while the surroundings remain stationary, or when both the cow and the surroundings are in motion but with different velocities or directions.
When the cow is grazing in a stationary field, there is no relative motion as both the cow and the field are moving together with zero relative velocity.
However, if the cow is walking across the field or if the field is being traversed by other elements such as wind or water currents, relative motion between the cow and the surroundings arises.
Additionally, if the cow is stationary while the field is being traversed by, for example, a strong wind, relative motion occurs.
In essence, relative motion between the cow and its surroundings happens when there is a difference in their velocities or directions of movement.
