If potassium permanganate was placed in a solution of boiling water (100°C), would the rate of diffusion be greater than diffusion in cold water? Would diffusion of potassium permanganate in boiling water be greater than diffusion in warm water?
The rate of diffusion increases as temperature increases.Hence, the rate of diffusion will be the greatest in boiling water then warm water and cold water at last
The movement of molecules along a concentration gradient is known as diffusion. It is a significant process that all living things go through. Diffusion facilitates the flow of materials into and out of cells. Increased energy from higher temperatures causes the molecules to move more quickly, speeding up the diffusion process. Lower temperatures cause the molecules' energy to drop, which lowers the diffusion rate. The rate of diffusion increases with increasing concentration differences. The particles will move and mix more quickly at a greater temperature because they will have more kinetic energy.
Hence, the diffusion rate will be boiling water>warm water>cold water

Two subgroups of a population separated by a river are rejoined when a drought causes the river to run dry. Assuming that speciation has not yet occurred, what is true about the two subgroups?
A. Speciation will speed up since there will be more competition
between the subgroups.
B. The likelihood that speciation will be completed will decrease.
C. The two subgroups will still be reproductively isolated and unable
to mate.
D. New traits that resulted from mutation will not flow between the
subgroups.
When separated subgroups of a population are rejoined due to drought, increased gene flow reduces reproductive isolation and lowers the likelihood of speciation. The correct answer to the question is B.
When two subgroups of a population are separated by a geographic barrier, such as a river, reproductive isolation occurs, which can lead to speciation over time. However, when a drought causes the river to run dry and the subgroups are rejoined, gene flow between the subgroups increases. This increased gene flow can reduce reproductive isolation and decrease the likelihood of speciation. Therefore, option B is correct. Option A is incorrect because increased competition between the subgroups does not necessarily speed up speciation. Option C is incorrect because when the subgroups are rejoined, they can interbreed and are no longer reproductively isolated. Option D is also incorrect because traits resulting from mutation can flow between the subgroups due to increased gene flow.For more questions on drought

2. How are the amino acids formed from the codon in Mutation #2 different from those formed from the original codon pattern?
Mutations are caused by the alteration in the nucleotide bases. These altered bases synthesize diverse amino acids relying upon nucleotide base sequences that code for a specific amino acid.
What is Mutation?A mutation may be defined as sudden, stable, and inheritable transformations in the sequence of the genome of an organism.
Mutations can bring a different code for amino acid sequences that results in the synthesis of a particular type of protein.
Before mutation amino acids formed from the codon are specific to their nucleotide bases but mutation causes the alteration in the nucleotide bases which alters the sequence of amino acid and proteins as well.
Therefore, it is well described above.

What is the cell cycle?The cell cycle is a series of steps that initiate with cell growth (G1) and ends with cell division (mitosis).
The cell cycle can be divided into interphase (G1, S and G2) and mitotic stage (cell division and cytokinesis).
The Synthesis (S) step can be defined as the interphase stage where DNA replication occurs.
Growth 1 (G1) and Growth 2 (G2) are fundamental stages where the cell prepares for its division by synthesizing key proteins required during mitosis.
Mitosis is the cell division process where duplicated genetic material (DNA) separate and two genetically identical new daughter cells form.
