The correct choice is D.
This is because symbiosis is the relationship between two different species, and out of all 4 of those choices, only D demonstrates the relationship between two DIFFERENT species (a bee and a plant).
The fact that it rotates on an axis and rotates around the sun causes the seasons to change over a year. Once every year it orbits around the sun and based on the placing of the Earth it depicts the season.
A characteristics that helps an organism to survive and reproduce is the best description of an adaptation.
Option D
<u>Explanation</u>:
Adaptation is simply defined as the evolutionary process of the organism when they feel comfortable to their natural place of existence. The process takes place in many generation to generation and it is passed on with genetic inheritance. With its biological phenomena it explains a trait in organisms which helps animal to survive and reproduce. It is also process of changing to different places for the organisms. Adaptation happens through mutation or natural selection.
Answer:
The cells change after being exposed to the chemical, and this change is passed to the next generation of cells.
Explanation:
A mutation is any change, whether big or small, that occurs to the nucleotide sequence of a gene in a cell as caused by mistake during replication or induced by a mutation causing substance. These mutation-causing substances are called MUTAGEN.
A MUTAGEN is any substance that causes genetic mutation in an organism's cell. These changes in the nucleotide sequence can affect one or more phenotypic characteristics of the affected organism, which is also passed to offsprings because it is a genetic change.
Hence, a plant cell exposed to this mutagen will be induced to mutate.
Hence, the cells changing after being exposed to the chemical, which is also passed to the next generation of cells best provides explanation that the chemical is a MUTAGEN.
