Q13What is one of the primary functions of prolactin, a hormone produced by the pituitary gland?
✓ Correct answer: C. Milk production stimulation
The endocrine system consists of a group of organs that release hormones directly into the bloodstream. Its main roles are hormone production and internal communication and coordination. The major glands in the endocrine system include the pineal, hypothalamus, pituitary, thyroid, parathyroid, thymus, adrenal, pancreas, and ovaries or testes. These glands secrete hormones into the blood to regulate the function of other organs and tissues in the body. One of the functions of prolactin is to stimulate milk production. The thymus is responsible for promoting healthy immune system development. The adrenocorticotropic hormone regulates blood pressure. The luteinizing hormone is involved in estrogen regulation.
Q14In the process of cellular respiration, what does glycolysis convert to what?

Glycolysis converts glucose to pyruvate in the process of cellular respiration. Cellular respiration occurs when chemical energy of food molecules is released and partially captured in the form of adenosine triphosphate (ATP).
Q15The element zinc (Zn) has an atomic number of 30. If the element carries a negative charge of 3, how many electrons does it possess?
✓ Correct answer: D. 33
Given that the atomic number of zinc is 30 and it bears a negative charge of 3, it will possess 33 electrons. When an element carries a negative charge, the charge is added to the atomic number, resulting in 30 + 3- = 33e When zinc is negatively charged by 3, it contains 33 electrons, not 10, 14, or 27.
Q16During the revision stage of writing, what should you do if you find that you did not maintain the proper voice throughout the writing process?
✓ Correct answer: C. Rework the material
If, during the revision stage of writing, you discover that you did not maintain the appropriate voice throughout the writing process, you should rework the material. Additionally, if the material is confusing, unclear, or needs simplification, it should be reworked. Unsupportive or redundant information should be deleted, material can be rearranged to create a clear flow or make a dramatic impact, and information can be added to provide more details, clarify ideas, or improve the overall flow.
Q17“What part of speech is the word traveled in the sentence 'Samantha and Jason traveled to Boston via the train'”
✓ Correct answer: A. Verb
A verb is a word that shows an action or state of being. Traveled is the word that describes the action in the sentence. Samantha and Jason are both nouns. Boston is a proper noun, which means it names a specific item and begins with a capital letter wherever it appears in a sentence. A pronoun is a word that replaces a noun (e.g., he/she, him/her, his/hers, himself/herself). Since there are no pronouns in this sentence, the choice of pronoun can be eliminated.
Q18The golf club was thrilled to have accomplished both of their objectives. Which word in the given sentence is modified by the adjective 'both'?

An adjective is a word that modifies a noun or pronoun; therefore, the adjective 'both' would need to modify a noun or pronoun. In this case, the adjective 'both' is describing the golf club's 'objectives'. The adjective 'both' does not modify the words: club, thrilled, or have.
