Q: Magnetite crystals in lava typically point to what geographic location? Read this paragraph and choose the correct option from the provided answers: Magnetite crystals in the lava point in the direction of the magnetic north pole. The different stripes of magnetic polarity reveal the different ages of the seafloor. Choices: - the equator - magnetic south pole - geographic north pole - magnetic north pole A:
magnetic north pole

Q: What is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond? Read this paragraph and choose the correct option from the provided answers: Figure 3.7 Sucrose is formed when a monomer of glucose and a monomer of fructose are joined in a dehydration reaction to form a glycosidic bond. In the process, a water molecule is lost. By convention, the carbon atoms in a monosaccharide are numbered from the terminal carbon closest to the carbonyl group. In sucrose, a glycosidic linkage is formed between carbon 1 in glucose and carbon 2 in fructose. Choices: - fructose - sulfate - chloride - sucrose A:
(Answer)
sucrose

Ques: Q: The ovaries produce estradiol and progesterone, which cause secondary sex characteristics and prepare the body for? Read this paragraph and choose the correct option from the provided answers: cells. The ovaries produce estradiol and progesterone, which cause secondary sex characteristics and prepare the body for childbirth. Choices: - breathing - adulthood - movement - childbirth A:
Ans: childbirth

Q: What is the pair of bean-shaped organs that filters blood and produces urine? Read this paragraph and choose the correct option from the provided answers: The kidneys are a pair of bean-shaped organs just above the waist. They are important organs with many functions in the body, including producing hormones, absorbing minerals, and filtering blood and producing urine. Choices: - heart - lungs - arteries - kidneys A:
(A).
kidneys

Ques:Q: Earthquakes have both longitudinal and transverse components, and these travel at what? Read this paragraph and choose the correct option from the provided answers: Earthquakes, essentially sound waves in Earth's crust, are an interesting example of how the speed of sound depends on the rigidity of the medium. Earthquakes have both longitudinal and transverse components, and these travel at different speeds. The bulk modulus of granite is greater than its shear modulus. For that reason, the speed of longitudinal or pressure waves (Pwaves) in earthquakes in granite is significantly higher than the speed of transverse or shear waves (S-waves). Both components of earthquakes travel slower in less rigid material, such as sediments. P-waves have speeds of 4 to 7 km/s, and S-waves correspondingly range in speed from 2 to 5 km/s, both being faster in more rigid material. The P-wave gets progressively farther ahead of the S-wave as they travel through Earth's crust. The time between the P- and S-waves is routinely used to determine the distance to their source, the epicenter of the earthquake. The speed of sound is affected by temperature in a given medium. For air at sea level, the speed of sound is given by. Choices: - identical speeds - the speed of light - the speed of sound - different speeds A:

Ans:different speeds

Q: What is the name for the disease in which cells divide out of control? Read this paragraph and choose the correct option from the provided answers: Knowledge gained by this basic research on yeast cells has been applied to practical problems. Scientists have developed drugs to treat cancer based on knowledge of the cell cycle. Cancer is a disease in which cells divide out of control. The new drugs interfere with the cell cycle of cancer cells, so the cells stop dividing. This is an example of applied science. The aim of applied science is to find solutions to practical problems. Applied science generally rests on knowledge gained by basic science. Choices: - diabetes - mutation - angina - cancer A:
cancer
