"Gravitational attraction" is initially responsible for the formation of the clumps of matter within this interstellar cloud.
<u>Answer:</u> Option C
<u>Explanation:</u>
About 4.6 billion years ago, the solar systems were a bunch of gases and dusts, referred to solar nebula. Gravity squeezed the material as it started to rotate, creating the sun at the middle of the fog.
The rest of the material began to accumulate with the sunrise. The smaller particles moved together to form larger particles that were connected by gravity. As lumps develop, gravity increases and turns into kinetic energy of moving particles that collide and produce heat.
Mycorrhizae fungus increases the area of the root for absorbing water and minerals from the soil.
Mycorrhizae will develop a mutualism symbiosis with the plant since they both get a benefit. <span>Mycorrhizae will get food from the plant and plant got more water and minerals.
Parasitic fungus only steals food from the plant without giving any benefit to the plant.</span>

Helium is extracted in a few places in the world, namely USA, Algeria, Russia and Qatar. Helium is abundant in space, where it's produced as a product of the fusion reaction inside stars such as the sun.
Asking a question is the first part of the scientific process (followed by research, hypothesis, experiment, data/analysis and conclusion). A question that can be answered using the scientific process must have some answers, must be able to be tested or tried through an experiment and must lead to a supposition or proposed explanation that is verified.
Answer:
D. They take up the usable forms of nitrogen found in soil
