Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.
The type of sensor the meteorologists should use is Radar sensor.
<h3>Who is a meteorologist?</h3>
A meteorologist is a scientist who studies and works in the field of meteorology with the purpose of understanding or predicting the Earth's atmospheric phenomena.
The tools used by meteorologists in studying atmospheric
phenomena or conditions include:
- Thermometer for measuring air and sea surface temperature.
- Barometer for measuring atmospheric pressure.
- Hygrometer for measuring humidity.
- Anemometer for measuring wind speed.
- Pyranometer for measuring solar radiation.
- Rain gauge for measuring rainfall over a set period of time
- Radar sensor for observing severe storms.
Therefore, the type of sensor the meteorologists should use is Radar sensor.
In conclusion, a meteorologist should use Radar sensors to detect and predict the atmospheric phenomena in stormy weather.

B. False
Protoplasm- includes the nucleus
Cytoplasm- excludes the nucleus
The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:
1,000 x 1,000 = 1,000,000 km²
Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:
1,000,000 x 10 = 10,000,000
So we have a density of 10 million earthworms per square km.
Answer:
Option B, ![18.11 \frac{N}{cm^{2}}](https://tex.z-dn.net/?f=18.11%20%5Cfrac%7BN%7D%7Bcm%5E%7B2%7D%7D)
Explanation:
Given-
The average surface area of one foot pad of an elephant is
![cm^{2}\\](https://tex.z-dn.net/?f=cm%5E%7B2%7D%5C%5C)
Weight of an Asian elephant is
newton
As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.
Thus, pressure on one foot pad of elephant is ![\frac{52900}{2920} \frac{N}{cm^{2}} \\](https://tex.z-dn.net/?f=%5Cfrac%7B52900%7D%7B2920%7D%20%5Cfrac%7BN%7D%7Bcm%5E%7B2%7D%7D%20%5C%5C)
![= 18.11\frac{N}{cm^{2}}](https://tex.z-dn.net/?f=%3D%2018.11%5Cfrac%7BN%7D%7Bcm%5E%7B2%7D%7D)
Hence, option B is correct answer
