Answer: They had more food to support more people.
Explanation:
The coarse focus knob on the SI V-Scope lowers and raises the microscope stage and uses power to focus.
The coarse focus knob on most microscopes is located around the bottom center part of the arm of the microscope as illustrated in the image below. The larger of the two knobs and one that is closest to the microscope's arm is the coarse adjustment knob.
Only the lowest power objective lens should be used with the coarse focus knob. You will only need to utilize the fine focus once it is in focus. With higher lenses, using the coarse focus could cause the lens to fall into the slide.
Focus (coarse), The coarse focus knob is used to roughly or almost focus the specimen. Focus (fine), After bringing the image into focus with the coarse focus knob, use the fine focus knob to make it more sharply focused.

Answer:
DNA replication does not occur prior to the second cell division during meiosis.
Explanation:
The mitosis and meiosis are the types of cell division which differ in the production of a number of daughter cell that is mitosis produces two daughter cells and the meiosis results in four daughter cells.
The mitosis results in the two diploid cells as DNA replication doubles the amount of DNA which got equally distributed in the cells.
During meiosis which proceeds in two phases: meiosis I and II, the DNA replication take place before meiosis which doubles the amount of DNA and the double amount in two daughter cells but no replication takes place before meiosis II, therefore, the amount is distributed from the divided genes.
Thus, the selected option is the correct answer.
The answer is B. Multiple food chains make up a food web of an ecosystem. A food web is made up of multiple food chains, and shows the relationships between different organisms in an ecosystem.
