Answer:
b. false
Explanation:
The cell cycle consists of three states: Interphase, Cell division (mitosis) and Resting.
Interphase is composed of phases G1, S and G2. during this state the cell replicates the genetic material of its chromosomes to prepare itself for cell division
In G1 the cell synthesizes mRNA and proteins that the cell will need during mitosis.
In S the cell replicates the genetic material of its chromosomes to prepare itself for cell division. At the end of this phase each chromosome is composed of two sister chromatides.
In G2 the cell grows and and more proteins synthesized for mitosis.
Mitosis is the production of two daughter cells from a sinlge one. During the entire mitosis the chromosomes are duplicated in the cell until finally, the genetic material is distributed in two cells after cytokinesis.
According to the above, it can be seen that the chromosomes in a cell that is in the cell cycle do not necessarily have sister chromatids. For example, chromosomes during G1 do not have sister chromatids.
Answer:
I'd Say A because it talks about slowing down the plants and removing stuff from the soil. Fire and smoke only cause problems for the surrounding area by blocking the sun and burning the ground, removing materials plants need for life. Then when it rains all the acidic stuff kills the ground as well.

Answer:
The law of conservation of mass
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
