Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
Answer:
The eruption of the volcano made the dark red walking beans more visible. Consequently, the quantity of dark red beans consumed increased during days four, five, and six. If the pollution persisted, the population of dark red walking beans would dwindle over time.
In metaphase, anaphase and telophase of meiosis 2 before cytokinesis the condition prevails.
Explanation:
Meiosis is the cell division process that occurs in gamete precursor cells to create gametes. It's a reduction division since the progenitor cells are diploid while the gametes are haploid.
During meiotic division, the cells first go through DNA replication that doubles the DNA content of each chromosome.
Then, via meiosis I, the cell experiences reduction division, transforming the diploid cell into a haploid cell. Thus, a cell with 10 chromosomes becomes one with 5 chromosomes. However, the DNA amount per chromosome remains doubled. This is corrected by the second meiotic division, where each chromosome splits into chromatids with a standard DNA content.
So at each stage of meiosis II,
until cytokinesis occurs, the cells should remain in a haploid state with double the DNA content. [[TAG_45]]
It is an independent variable.
The independent variable in an experiment is the one that is deliberately modified or adjusted in order to observe its effects.
In this case, the varying amounts of caffeine administered to the dogs are the factor that changes—the control group receives no caffeine, the second group gets 10 mg of caffeine, while the third group gets 50 mg of caffeine each.
Thus, the amount of caffeine given to the dogs is the independent variable being altered.
