Answer:
At sea level, air pressure is greatest because it is caused by the weight of the entire column of atmosphere at that altitude over that location. As altitude increases, the column of atmosphere gets shorter, and so less weight is pressing down at a given altitude, so atmospheric pressure is reduced.
The statement that describes this prediction is as follows:
- The prediction is useful because it explains what observations will be made if a hypothesis is true.
Thus, the correct option is D.
<h3>What is Herbicide?</h3>
Herbicide may be defined as a chemical agent that is responsible for destroying or inhibiting the growth of a particular plant as compared to the normal one.
The projection is necessary because it supports the product after a one-year duration. So for example, if after one year there is undoubtedly a reduction in the intermediate height of the tomato plants, then we can absolutely say that it is because of the existence of NoGro herbicide which is supplied in water.
Therefore, it is well described above.

Answer:
"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."
It is the mode through which a neuron transports electrical signals.
Explanation:
- Option - (a) is the best choice to choose from,
- <u>The refractory period :</u>
A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
The nucleus of the cell directs cell activity and acts like the control center. This is the place where gene activity is controlled in terms of the replication of the genes. In addition the movement and actions of the cell are also dictated from the nucleus.
Since Australia is located in the Pacific ocean, extremes of weather and climate happen throughout a season. El Niño is traditionally defined as a dry climate with reduced rainfall; in this happens to be more extreme in Australia because of its location. La Niña on the other hand is traditionally defined as a wet or cool climate with lots of rainfall; and this is indifferent as La Niña in Australia tend to be more extreme too.
