[QUESTION]What do these two changes have in common? baking cookies a piece of avocado turning brown
[OPTIONS](A) Both are only physical changes. (B) Both are caused by heating. (C) Both are chemical changes. (D) Both are caused by cooling.
Both are chemical changes.
Step 1: Think about each change. Baking cookies is a chemical change. The type of matter in the cookie dough changes when it is baked. The cookie dough turns into cookies! A piece of avocado turning brown is a chemical change. The avocado reacts with oxygen in the air to form a different type of matter. If you scrape off the brown part of the avocado, the inside will still be green. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the avocado. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Baking is caused by heating. But a piece of avocado turning brown is not. Both are caused by cooling. Neither change is caused by cooling.

[QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[OPTIONS](A) The magnitude of the magnetic force is smaller in Pair 1. (B) The magnitude of the magnetic force is the same in both pairs. (C) The magnitude of the magnetic force is smaller in Pair 2.
The magnitude of the magnetic force is smaller in Pair 1.
The magnets in Pair 1 attract. The magnets in Pair 2 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force. Magnet sizes affect the magnitude of the magnetic force. Imagine magnets that are the same shape and made of the same material. The smaller the magnets, the smaller the magnitude of the magnetic force between them. Magnet A is the same size in both pairs. But Magnet B is smaller in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is smaller in Pair 1 than in Pair 2.

[QUESTION]Complete the statement. Calcium is ().
[OPTIONS](A) a compound (B) an elementary substance
an elementary substance
You can tell whether calcium is an elementary substance or a compound by counting the number of atomic symbols in its chemical formula. An atomic symbol consists of either one capital letter or a capital letter followed by one or two lowercase letters. The chemical formula for calcium contains one atomic symbol: Ca. So, the formula tells you that calcium is composed of only one chemical element. Since calcium is composed of only one chemical element, calcium is an elementary substance.

[QUESTION]Based on this information, what is Chance's phenotype for the fur texture trait?
[OPTIONS](A) soft fur (B) rough fur
rough fur
You need to determine Chance's phenotype for the fur texture trait. First, consider the alleles in Chance's genotype for the fur texture gene. Then, decide whether these alleles are dominant or recessive. The allele for rough fur (F) is dominant over the allele for soft fur (f). This means F is a dominant allele, and f is a recessive allele. Chance's genotype of Ff has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Chance's phenotype for the fur texture trait must be rough fur.

[QUESTION]Think about the magnetic force between the magnets in each pair. Which of the following statements is true?
[OPTIONS](A) The magnitude of the magnetic force is greater in Pair 1. (B) The magnitude of the magnetic force is greater in Pair 2. (C) The magnitude of the magnetic force is the same in both pairs.
The magnitude of the magnetic force is greater in Pair 1.
The magnets in Pair 2 attract. The magnets in Pair 1 repel. But whether the magnets attract or repel affects only the direction of the magnetic force. It does not affect the magnitude of the magnetic force. Distance affects the magnitude of the magnetic force. When there is a smaller distance between magnets, the magnitude of the magnetic force between them is greater. There is a smaller distance between the magnets in Pair 1 than in Pair 2. So, the magnitude of the magnetic force is greater in Pair 1 than in Pair 2.

[QUESTION]Assume all other forces on Kinsley are balanced. Which statement describes the forces on Kinsley?
[OPTIONS](A) The forces are balanced, so there is no net force on Kinsley. (B) The forces are unbalanced, so there is a net force on Kinsley.
The forces are unbalanced, so there is a net force on Kinsley.
To determine if there is a net force on Kinsley, look at the forces: Earth's gravity is pulling Kinsley down with a force of 600 N. The seat of the cart is pushing Kinsley up with a force of 1,200 N. The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Kinsley.

[OPTIONS](A) Both are caused by heating. (B) Both are only physical changes. (C) Both are chemical changes. (D) Both are caused by cooling.
Both are chemical changes.
Step 1: Think about each change. Acid rain weathering a marble statue is a chemical change. The acid rain reacts with the outside of the statue and breaks it down into a different type of matter. This new matter is then washed away by the rain. Acid rain is a type of pollution. It forms when smoke from automobiles and factories mixes with water in clouds. Acid rain is a type of pollution. It forms when automobiles and factories release smoke containing sulfur or nitrogen. Some of these chemicals react with water in the atmosphere. The reaction forms droplets of water that can fall back to the ground as acid rain. Deep-frying chicken is a chemical change. The heat causes the matter in the chicken to change. Cooked chicken and raw chicken are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Cooking is caused by heating.
