Front

Part of the chromosome where spindle fibers attach

Back

Centromere: The region of a chromosome where the two sister chromatids are joined and where spindle fibers attach during cell division.

Front

Chromatin is found in the cell's

Back

Nucleus: The membrane-bound organelle that contains the cell's genetic material in the form of chromatin.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed by the scientist to observe its effect on the dependent variable.

Front

What are the monomers of nucleic acids?

Back

Nucleotides: The basic building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What property of water is demonstrated when a carnation flower absorbs blue dye?

Back

Capillary action: The ability of water to flow in narrow spaces without the assistance of external forces, allowing plants to transport water and nutrients.

Front

What is the function of the centromere during cell division?

Back

The centromere ensures that sister chromatids are properly separated into daughter cells during mitosis.

Front

Where is chromatin located in a cell?

Back

Chromatin is located in the nucleus, where it condenses to form chromosomes during cell division.

Front

What does the independent variable represent in a graph?

Back

The independent variable is typically plotted on the X-axis and represents the variable that is manipulated in an experiment.

Front

What are the components of a nucleotide?

Back

A nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

Front

What is capillary action and why is it important for plants?

Back

Capillary action is the ability of water to move through small spaces, which is crucial for the transport of water and nutrients in plants.
