What phase is this cell in?

• Anaphase

• Telophase

• Interphase

• Metaphase

Answer explanation

The cell is in Metaphase because the chromosomes are aligned at the center of the cell, ready to be separated into two daughter cells.

What phase is this cell in?

• Anaphase

• Cytokinesis

• Interphase

• Prophase

Answer explanation

The cell is in Prophase because it is the phase where the chromosomes condense and become visible under a microscope, preparing for cell division.

In which phase of mitosis do chromosomes condense or come together?

• Interphase

• Anaphase

• Prophase

• Cytokinesis

Answer explanation

In the phase of mitosis where chromosomes condense or come together is Prophase.

In which phase of mitosis do chromosomes line up along the middle of the cell?

• Interphase

• Prophase

• Metaphase

• Anaphase

Answer explanation

In metaphase, chromosomes line up along the middle of the cell, ready to be separated into two daughter cells.

In which phase of mitosis do the chromosomes split apart?

• Interphase

• Prophase

• Metaphase

• Anaphase

Answer explanation

In Anaphase of mitosis, the chromosomes split apart and move towards opposite poles of the cell, ensuring each daughter cell receives a complete set of chromosomes.

Which statement is a part of the cell theory?

• all cells come from preexisting cells

• bacteria are prokaryotic cells

• eukaryotic cells are complex

• humans are multicellular

Answer explanation

Students in Mrs. Clark's science class are investigating a substance that has the following properties

-shiny

-bends easily

-hard, not easily broken

Based on these properties how would you classify the substance?

• metal

• nonmetal

• metalloid

Answer explanation

Based on the properties of being shiny, bending easily, and hard to break, the substance can be classified as a metal.

The same student works with a new substance. He concludes it conducts electricity very well. It has a very shiny luster. When he hammers it, it simply dents and flattens. What is the most likely substance type?

• Metal

• Metalloid

• Nonmetal

To make an object move you must first apply ---

• an opposing force

• an unbalanced force

• a stationary force

• a vertical force

Answer explanation

To make an object move you must first apply an unbalanced force, as it is necessary to overcome inertia and initiate motion.
