Question:

In the process of cellular respiration, glucose and oxygen undergo chemical reactions to form new molecules. Select the correct sequence of events that describe how food is rearranged through these reactions to support the growth and release energy in an organism.

Answer Choices:

A) Glucose and oxygen react to form carbon dioxide, water, and ATP.
B) Glucose is broken down into oxygen, which combines with carbon dioxide to form ATP.
C) Oxygen is converted into glucose and water, releasing carbon dioxide and energy.
D) Carbon dioxide and water are rearranged to form glucose, releasing energy.

✅ Answer:

Glucose and oxygen react to form carbon dioxide, water, and ATP.

💡 Explanation:

In cellular respiration, glucose and oxygen are the reactants that undergo chemical reactions in the mitochondria of cells.
These reactions form carbon dioxide, water, and ATP (adenosine triphosphate), which provides energy for cellular processes and supports growth.

Question:

Which of the following statements correctly describe the relationship between the amplitude of a wave and the energy it carries?

Answer Choices:

A) A wave with a higher amplitude carries more energy than a wave with a lower amplitude.
B) The energy of a wave is independent of its amplitude.
C) If the amplitude of a wave doubles, the energy carried by the wave quadruples.
D) A wave with a lower amplitude carries more energy than a wave with a higher amplitude.
E) The amplitude of a wave does not affect its energy at all.

✅ Answer:

A wave with a higher amplitude carries more energy than a wave with a lower amplitude.; If the amplitude of a wave doubles, the energy carried by the wave quadruples.

💡 Explanation:

The amplitude of a wave is directly related to the energy it carries.
A higher amplitude means the wave carries more energy.
Specifically, the energy carried by a wave is proportional to the square of its amplitude, which means if the amplitude doubles, the energy increases by a factor of four.

Question:

Which of the following statements about the Declaration of Independence are true based on primary source evidence?

Answer Choices:

A) The Declaration of Independence was written to announce the American colonies' separation from Britain.
B) The Declaration of Independence outlines the principles of individual liberty and government by consent.
C) The Declaration of Independence was written to establish a new form of government immediately.
D) The Declaration of Independence was intended to list grievances against the British Crown.
E) The Declaration of Independence was primarily a philosophical document with no immediate political purpose.

✅ Answer:

The Declaration of Independence was written to announce the American colonies' separation from Britain.; The Declaration of Independence outlines the principles of individual liberty and government by consent.; The Declaration of Independence was intended to list grievances against the British Crown.

💡 Explanation:

The Declaration of Independence was written to declare the American colonies' independence from British rule, outline key principles such as individual liberty and government by consent, and list grievances against the British monarchy.
It was not written to immediately establish a new form of government or as a purely philosophical document.

Question:

Which of the following equations represent a circle with center at (3, -2) and radius 5?

Answer Choices:

A) (x - 3)^2 + (y + 2)^2 = 5
B) (x - 3)^2 + (y + 2)^2 = 25
C) (x + 3)^2 + (y - 2)^2 = 5
D) (x - 3)^2 + (y - 2)^2 = 25
E) (x + 3)^2 + (y + 2)^2 = 25

✅ Answer:

(x - 3)^2 + (y + 2)^2 = 25

💡 Explanation:

The standard form of a circle's equation is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.
For a circle with center (3, -2) and radius 5, the equation is (x - 3)^2 + (y + 2)^2 = 25, since 5^2 = 25.

Question:

Which of the following expressions is a difference of squares and can be factored using the formula $a^2 - b^2 = (a + b)(a - b)$ ?

Answer Choices:

A) x^2 - 16
B) x^2 + 16
C) x^2 - 2x
D) x^2 + 2x + 1

✅ Answer:

x^2 - 16

💡 Explanation:

The expression $x^2 - 16$ is a difference of squares because it can be rewritten as $x^2 - 4^2$ , which fits the formula $a^2 - b^2 = (a + b)(a - b)$ with $a = x$ and $b = 4$ .
Thus, it factors to $(x + 4)(x - 4)$ .
