I think the most accepted Theory to make up living things is the cell theory.
Genetic variation occurs.
Mutations are not copied over and over again.
Plant cells are specialized for life in a hypotonic environment.
Answer: Option A
<u>Explanation:</u>
A cell which lacks the cell wall, will expand and burst. At the point when set in a hypertonic solution, a cell without a cell wall will lose water to the surrounding, wilt and presumably die.
In a hypertonic arrangement, a cell with a cell divider will lose water as well. The plasma layer pulls from the cell wall as it withers, a procedure called plasmolysis. Thus it can be inferred that plant cell are specialized for life in a hypotonic environment.
<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.
