Q: What kind of gland produces an oily substance that waterproofs the hair and skin? Read this paragraph and choose the correct option from the provided answers: oily substance produced in the dermis by a sebaceous gland that waterproofs the hair and skin. Choices: - secretion gland - nail gland - mucous gland - sebaceous gland A:
sebaceous gland

Q: A can of warm soda will fizz more because increasing the temperature decreases the what of a gas? Read this paragraph and choose the correct option from the provided answers: A: A can of warm soda will fizz more because increasing the temperature decreases the solubility of a gas. Therefore, less carbon dioxide can remain dissolved in warm soda than in cold soda. Choices: - Acidity - humidity - viscosity - solubility A:
solubility

Q: Q: What are the two metals within a battery called? Read this paragraph and choose the correct option from the provided answers: These values suggest that water should be oxidized at the anode because a smaller potential would be neededusing reaction (ii) for the oxidation would give a less-negative cell potential. When the experiment is run, it turns out chlorine, not oxygen, is produced at the anode. The unexpected process is so common in electrochemistry that it has been given the name overpotential. The overpotential is the difference between the theoretical cell voltage and the actual voltage that is necessary to cause electrolysis. It turns out that the overpotential for oxygen is rather high and effectively makes the reduction potential more positive. As a result, under normal conditions, chlorine gas is what actually forms at the anode. Now consider the cathode. Three reductions could occur:. Choices: - sheath and a cathode - anode and sheath - anode and diode - anode and a cathode A:
A: anode and a cathode

Question: Q: Which are the closest living relations to land plants? Read this paragraph and choose the correct option from the provided answers: outcompete the green tint of chlorophyll, making these species appear as varying shades of red. Other protists classified as red algae lack phycoerythrins and are parasites. Red algae are common in tropical waters where they have been detected at depths of 260 meters. Other red algae exist in terrestrial or freshwater environments. Green Algae: Chlorophytes and Charophytes The most abundant group of algae is the green algae. The green algae exhibit similar features to the land plants, particularly in terms of chloroplast structure. That this group of protists shared a relatively recent common ancestor with land plants is well supported. The green algae are subdivided into the chlorophytes and the charophytes. The charophytes are the closest living relatives to land plants and resemble them in morphology and reproductive strategies. Charophytes are common in wet habitats, and their presence often signals a healthy ecosystem. The chlorophytes exhibit great diversity of form and function. Chlorophytes primarily inhabit freshwater and damp soil, and are a common component of plankton. Chlamydomonas is a simple, unicellular chlorophyte with a pear-shaped morphology and two opposing, anterior flagella that guide this protist toward light sensed by its eyespot. More complex chlorophyte species exhibit haploid gametes and spores that resemble Chlamydomonas. The chlorophyte Volvox is one of only a few examples of a colonial organism, which behaves in some ways like a collection of individual cells, but in other ways like the specialized cells of a multicellular organism (Figure 23.24). Volvox colonies contain 500 to 60,000 cells, each with two flagella, contained within a hollow, spherical matrix composed of a gelatinous glycoprotein secretion. Individual Volvox cells move in a coordinated fashion and are interconnected by cytoplasmic bridges. Only a few of the cells reproduce to create daughter colonies, an example of basic cell specialization in this organism. Choices: - mammals - arthropods - sporozoans - charophytes A:
Answer: charophytes

*Question*
Q: What is a sugar that is found in fruits? Read this paragraph and choose the correct option from the provided answers: In the Figure below , you can see structural formulas for glucose and two other sugars, named fructose and sucrose. Fructose is a sugar that is found in fruits. It is an isomer of glucose. Isomers are compounds that have the same atoms but different arrangements of atoms. Do you see how the atoms are arranged differently in fructose than in glucose? You're probably most familiar with the sugar sucrose, because sucrose is table sugar. It's the sugar that you spoon onto your cereal or into your iced tea. Choices: - ethanol - glucose - sucrose - fructose A:
**Answer**
fructose
