Explanation:
The classical cell theory was proposed by Theodor Schwann in 1839. There are three parts to this theory. The first part states that all organisms are made of cells. The second part states that cells are the basic units of life. These parts were based on a conclusion made by Schwann and Matthias Schleiden in 1838, after comparing their observations of plant and animal cells. The third part, which asserts that cells come from preexisting cells that have multiplied, was described by Rudolf Virchow in 1858, when he stated omnis cellula e cellula (all cells come from cells).
Since the formation of classical cell theory, technology has improved, allowing for more detailed observations that have led to new discoveries about cells. These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within cells.
Answer:
Easy
Explanation:
In this regard, water is essential simply because it's a liquid at Earth-like temperatures. Because it flows, water provides an efficient way to transfer substances from a cell to the cell's environment.

Answer: 4
Explanation:
Fungi(mushrooms) are heterotrophs and they cannot fix nitrogen from the atmosphere and they must obtain it from their environment. They are using complex organic compounds as a source of carbon.
Most plants can fix carbon which are 1. Grass 2. Maple trees 3. Algae and hat are why they are incorrect answers because from this question only 4. mushrooms can fix carbon.
Answer:
Explanation:
1)It is better to stick to the lower trophic levels around 2 because it is more consumable.
At the lowest trophic level, there is the lowest consumption of energy. As a result, more people can be fed with the lower trophic levels than the higher trophic levels.
Edit: Sorry forgot to do question 2
2) Different levels in a food web...
