What is the function of the nucleus in a cell?

• The function of the nucleus in a cell is to transport nutrients.

• The function of the nucleus in a cell is to provide structural support.

• The function of the nucleus in a cell is to control gene expression and store DNA.

• The function of the nucleus in a cell is to produce energy.

What is the difference between mitosis and meiosis?

• Mitosis results in two identical daughter cells, while meiosis results in four non-identical daughter cells.

• Mitosis results in four identical daughter cells, while meiosis results in two non-identical daughter cells.

• Mitosis and meiosis both result in two identical daughter cells.

• Mitosis and meiosis both result in four non-identical daughter cells.

What is the purpose of Punnett squares in genetics?

• To predict the possible outcomes of genetic crosses.

• To identify the genetic disorders in an individual.

What is the equation for aerobic respiration?

• glucose + oxygen -> carbon dioxide + water + energy (AMP)

• glucose + oxygen -> carbon dioxide + water + energy (ATP)

• glucose + oxygen -> carbon dioxide + water + energy (NADP)

• glucose + oxygen -> carbon dioxide + water + energy (ADP)

How does DNA determine the traits of an organism?

• DNA determines the traits of an organism through the interaction with the environment.

• DNA determines the traits of an organism through random mutations.

• DNA determines the traits of an organism through the influence of the organism's diet.

• DNA contains the genetic information that codes for the production of proteins, which determine the traits of an organism.

Analyze

• Examine in detail to show meaning, and to identify elements and the relationship between them

• Set out purposes or reasons/make the relationships between things evident/provide why/how and support with relevant evidence.

• Apply knowledge and understanding to situations where there is a range of valid responses in order to make proposals.

• Judge or calculate the quality, importance, amount, or value of something.

Compare

• Support a case with evidence/argument

• Make an informed judgement

• Select and present the main points, without detail

• Identify/Comment on similarities/differences
