Explanation:
any of a group of RNA viruses that cause a variety of respiratory, gastrointestinal, and neurological diseases in humans and other animals
1. Venus- the weakest
2. Earth
3. Jupiter-the strongest
Magnetic fields protect planets and atmospheres from solar particles because those particles are charged (they respond to the magnetic field and move around it). All of the planets have magnetic fields, except for Venus and Mars. Jupiter which is the largest planet in our solar system, also has the largest magnetic field. It’s magnetic field is generated by its fast rotation
Adenosine triphosphate <span>(ATP)
is the energy source for muscle contraction. Myosin is a motor protein that
interacts with actin filaments. When ATP is available, it binds to myosin and
is being hydrolyzed resulting in the conformational changes in myosin. This
leads to the movement of myosin relative to actin filaments.</span>
<h2>
Answer:</h2>
Option B) Nodules.
<h2>
Explanation:</h2>
- It is impossible for plants to fix atmospheric nitrogen(nitrogen present in soil) and hence they absorb nitrogen from the soil in the form of nitrates and ammonium.
- Plant absorbs nitrogen from soil through nodules present on roots.
- In case of leguminous(pulses) plant roots of the plant form a symbiotic association with nitrogen-fixing bacteria for example- Rhizobium.
- On the other hand if nitrates is directly absorbed by the plant, it is taken up by nitrate transporters which uses a proton gradient to power the nitrate to get transported.
- Absorbed nitrogen is transferred from root to shoot by xylem.
Result: Option B) is the correct answer.
