Answer the following question given this paragraph: Light moving from air into water is bent ___________ the normal. Q: Light moving from air into water is bent ___________ the normal? Choices: - less - thinly - Longly - more A:
more
Answer the following question given this paragraph: Cells make up all living things, including your own body. This picture shows a typical group of cells. But not all cells look alike. Cells can differ in shape and sizes. And the different shapes usually means different functions. Q: What small biological structures make up all living things, including the human body? Choices: - proteins - scales - lipids - cells A:
cells
Q: Answer the following question given this paragraph: You learned about the three rock types: igneous, sedimentary, and metamorphic. You also learned that all of these rocks can change. In fact, any rock can change to become any other type of rock. These changes usually happen very slowly. Some changes happen below Earth's surface. Some changes happen above ground. These changes are all part of the rock cycle. The rock cycle describes each of the main types of rocks, how they form, and how they change. Q: What are the three types of rocks? Choices: - igneous, sedimentary, mixed - igneous, orbital, metamorphic - opaque , sedimentary , metamorphic - igneous, sedimentary, metamorphic A:
A: igneous, sedimentary, metamorphic
Question: Answer the following question given this paragraph: Compounds like sodium chloride form structures called crystals. A crystal is a rigid framework of many ions locked together in a repeating pattern. Ions are electrically charged forms of atoms. You can see a crystal of sodium chloride in the Figure below . It is made up of many sodium and chloride ions. Q: Compounds like sodium chloride form structures called what? Choices: - ions - microorganisms - hydrocarbons - crystals A:
Answer: crystals

Answer the following question given this paragraph: Recall that ecology is the study of how living organisms interact with each other and with their environment. But how do organisms interact with each other? Organisms interact with each other through various mechanisms, one of which is competition. Competition occurs when organisms strive for limited resources. Competition can be for food, water, light, or space. This interaction can be between organisms of the same species (intraspecific) or between organisms of different species (interspecific). Q: What is the study of how living organisms interact with each other and with their environment? Choices: - botany - zoology - genetics - ecology A:
**Answer**
ecology
Answer the following question given this paragraph: CHAPTER REVIEW 27.1 Anatomy and Physiology of the Male Reproductive System Gametes are the reproductive cells that combine to form offspring. Organs called gonads produce the gametes, along with the hormones that regulate human reproduction. The male gametes are called sperm. Spermatogenesis, the production of sperm, occurs within the seminiferous tubules that make up most of the testis. The scrotum is the muscular sac that holds the testes outside of the body cavity. Spermatogenesis begins with mitotic division of spermatogonia (stem cells) to produce primary spermatocytes that undergo the two divisions of meiosis to become secondary spermatocytes, then the haploid spermatids. During spermiogenesis, spermatids are transformed into spermatozoa (formed sperm). Upon release from the seminiferous tubules, sperm are moved to the epididymis where they continue to mature. During ejaculation, sperm exit the epididymis through the ductus deferens, a duct in the spermatic cord that leaves the scrotum. The ampulla of the ductus deferens meets the seminal vesicle, a gland that contributes fructose and proteins, at the ejaculatory duct. The fluid continues through the prostatic urethra, where secretions from the prostate are added to form semen. These secretions help the sperm to travel through the urethra and into the female reproductive tract. Secretions from the bulbourethral glands protect sperm and cleanse and lubricate the penile (spongy) urethra. The penis is the male organ of copulation. Columns of erectile tissue called the corpora cavernosa and corpus spongiosum fill with blood when sexual arousal activates vasodilatation in the blood vessels of the penis. Testosterone regulates and maintains the sex organs and sex drive, and induces the physical changes of puberty. Interplay between the testes and the endocrine system precisely control the production of testosterone with a negative feedback loop. Q: What is responsible for the physical changes of puberty? Choices: - nicotine - caffeine - adrenaline - testosterone A:
testosterone
