Answer:
Primary
Explanation:
Succession is a series of progressive changes in the composition of an ecological community over time. In primary succession, newly exposed or newly formed rock is colonized by living things for the first time.
B. Density
Density = mass/volume because it’s basically the concentration of mass. How much matter takes up the space. If you pack more matter into less space, it is more dense.
Answer: Avogrado's number, or 6.022 x 10^23
Explanation:
To convert from moles to atoms, multiply the molar amount by Avogadro's number. To convert from atoms to moles, divide the atom amount by Avogadro's number (or multiply by its reciprocal).
The answer is option a, that is " <span>electromagnetic repulsions</span><span>".
The sun generates energy by nuclear fusion, and converts a part of its mass into energy and nuclear fusion is the source of all energy that is released by the sun. The two things which are required for the process of nuclear fusion are high temperature and the high densities.
