Sinkholes form when limestone is slowly dissolved by acidic groundwater over geologic time. ... This process of dissolution can create large cavities in limestone. A sinkhole forms when the roof of a cavity in the limestone collapses and creates a depression at the land surface.
The nucleus during mitosis. Micrographs illustrating the progressive stages of mitosis in a plant cell. During prophase, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down.

Answer:
Bread, bananas and honey have carbohydrates.
Explanation:
The group fed a pre-race meal of bread with bananas and honey because bread, bananas and honey have high amount of carbohydrates which give quick energy to the athlete. This carbohydrate is a macromolecule which is quickly converted into micromolecule i. e. glucose that is absorbed by the cell and the mitochondria of the cell produces energy in the form of ATP that is used by the athlete in running.
Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
