Choice C is correct.
WHY: In meiosis, sex cells (eggs or sperm) are produced. This means that they must have <u>half </u>the number of chromosomes in each, and they must be each <u>UNIQUE</u>.
Thus, the other options (A,B,D) cannot be correct because the product of meiosis cannot be the exact copy of the parent cells, and so cannot have the same number of chromosomes either.
Answer:
D. Power is required in order for work to be applied on an object
Answer:
The given statement is True.
A human body is composed of around 60 percent of water, the average range is around 50-65 percent.

It helps in maintaining the internal body temperature through respiration and sweating.
It helps in excretion of waste material through urination.
It lubricates joints and acts as shock absorbent for the fetus, spinal cord, and brain.
Answer:
1. Cell
2. cell theory
3. Organismal theory
4. resolving power
Explanation:
The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).
2. Cell theory was formulated and developed by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.
It states:
1. Living organisms are made up of cells.
2. Cells are the basic unit of life.
3. Cells are formed from pre-existing cells.
4. Energy flows inside the cell.
5. DNA is passed on from cell to cell.
6. All cells have the same basic chemical composition.
3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.
4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
