Answer the following question given this paragraph: By losing an electron, the sodium atom becomes a sodium ion. It now has one less electron than protons, giving it a charge of +1. Positive ions such as sodium are given the same name as the element. The chemical symbol has a plus sign to distinguish the ion from an atom of the element. The symbol for a sodium ion is Na + . Q: What happens when a sodium atom loses an electron? Choices: - becomes calcium - gains a proton - combines with hydrogen - becomes sodium ion A:
becomes sodium ion
Answer the following question given this paragraph: Q: What is common in two eukaryotic proteins? Choices: - DNA - cells - translation - one domain A:
one domain
Q: Answer the following question given this paragraph: Male Urethra The male urethra passes through the prostate gland immediately inferior to the bladder before passing below the pubic symphysis (see Figure 25.3b). The length of the male urethra varies between men but averages 20 cm in length. It is divided into four regions: the preprostatic urethra, the prostatic urethra, the membranous urethra, and the spongy or penile urethra. The preprostatic urethra is very short and incorporated into the bladder wall. The prostatic urethra passes through the prostate gland. During sexual intercourse, it receives sperm via the ejaculatory ducts and secretions from the seminal vesicles. Paired Cowper's glands (bulbourethral glands) produce and secrete mucus into the urethra to buffer urethral pH during sexual stimulation. The mucus neutralizes the usually acidic environment and lubricates the urethra, decreasing the resistance to ejaculation. The membranous urethra passes through the deep muscles of the perineum, where it is invested by the overlying urethral sphincters. The spongy urethra exits at the tip (external urethral orifice) of the penis after passing through the corpus spongiosum. Mucous glands are found along much of the length of the urethra and protect the urethra from extremes of urine pH. Innervation is the same in both males and females. Q: What passes through the prostate gland immediately inferior to the bladder before passing below the pubic symphysis? Choices: - rectum - vagina - cerebellum - urethra A:
A: urethra
Question: Answer the following question given this paragraph: Power plants and factories account for more than a quarter of fossil fuel use. Power plants burn fossil fuels to generate electricity. Factories burn fossil fuels to power machines. Q: What do power plants burn to generate electricity? Choices: - nuclear fuel - biofuel - timber - fossil fuels A:
Answer: fossil fuels

Answer the following question given this paragraph: Respiratory Therapist Respiratory therapists or respiratory practitioners evaluate and treat patients with lung and cardiovascular diseases. They work as part of a medical team to develop treatment plans for patients. Respiratory therapists may treat premature babies with underdeveloped lungs, patients with chronic conditions such as asthma, or older patients suffering from lung disease such as emphysema and chronic obstructive pulmonary disease (COPD). They may operate advanced equipment such as compressed gas delivery systems, ventilators, blood gas analyzers, and resuscitators. Specialized programs to become a respiratory therapist generally lead to a bachelor's degree with a respiratory therapist specialty. Because of a growing aging population, career opportunities as a respiratory therapist are expected to remain strong. Q: Respiratory therapists or respiratory practitioners evaluate and treat patients diseases affecting what part of the body? Choices: - byproduct , heart , and blood vessels - brain, stomach, heart - heart, lungs, stomach - lung, heart, and blood vessels A:
**Answer**
lung, heart, and blood vessels
(Q).
Answer the following question given this paragraph: The Chromosomal Theory of Inheritance was consistent with Mendel's laws and was supported by the following observations: During meiosis, homologous chromosome pairs migrate as discrete structures that are independent of other chromosome pairs. The sorting of chromosomes from each homologous pair into pre-gametes appears to be random. Each parent synthesizes gametes that contain only half of their chromosomal complement. Even though male and female gametes (sperm and egg) differ in size and morphology, they have the same number of chromosomes, suggesting equal genetic contributions from each parent. The gametic chromosomes combine during fertilization to produce offspring with the same chromosome number as their parents. Q: During meiosis, each parent synthesizes gametes that contain only half of their complement of what? Choices: - receptors - neutrons - atoms - chromosomes A:
(A).
chromosomes
