If a substance is not able to be separated by physical means but is able to be separated by chemical means, it is a compound.
The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.

Explanation:
The Earth and the Moon are two space bodies that have each other as the closest to one another. Both of them have their own gravitational pull, with the one of the Earth being much greater, while the one of the Moon being weaker than it is expected for a body of its size. Nevertheless they influence each other with the gravitational pull, which is most noticeable on Earth.
The gravitational pull between these two space bodies is the greatest when they are the closest to each other, while it is the smallest when they are the furthest from each other. On January 10 the distance between Earth and the Moon is the smallest and it is 360,048 km, so the gravitational pull is the greatest on this date. On December 19 the distance between Earth and the Moon is the greatest and it is 406,276 km, so the gravitational pull is the smallest.
Ecosystem energy flow. Energy's life moves. The energy cycle is based on the flow of energy in an ecosystem through various trophic levels. The cycling energy and nutrients obtained from various external sources maintain our ecosystem.
The responses are A, B, and E. A) Because the sun provides the entire ecosystem with energy, it is a major source of energy. B) because photosynthesis is the process in which plants convert radiant energy from the sun into chemical energy to form sugar-known glucose. E) I believe because, as it moves throughout the ecosystem, the amount of energy at each trophic level decreases.
I hope this helped!!!
