Answer the following question given this paragraph: During this ester bond formation, three water molecules are released. The three fatty acids in the triacylglycerol may be similar or dissimilar. Fats are also called triacylglycerols or triglycerides because of their chemical structure. Some fatty acids have common names that specify their origin. For example, palmitic acid, a saturated fatty acid, is derived from the palm tree. Arachidic acid is derived from Arachis hypogea, the scientific name for groundnuts or peanuts. Fatty acids may be saturated or unsaturated. In a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are saturated with hydrogen; in other words, the number of hydrogen atoms attached to the carbon skeleton is maximized. Stearic acid is an example of a saturated fatty acid (Figure 3.14). Q: Fats are also called triacylglycerols or triglycerides because of their what? Choices: - atomic number - chemical weight - elemental type - chemical structure A:
(Answer)
chemical structure
Ques: Answer the following question given this paragraph: In intelligent mammals, such as primates, the cerebrum is larger compared to the rest of the brain. A larger cerebrum allows primates to develop higher levels of intelligence. Primates have the ability to learn new behaviors. They also engage in complex social interactions, such as fighting and play. Q: What part of the brain is largest in intelligent mammals? Choices: - thallus - manubrium - cortex - cerebrum A:
Ans: cerebrum

Answer the following question given this paragraph: Understanding Pigments Different kinds of pigments exist, and each absorbs only certain wavelengths (colors) of visible light. Pigments reflect the color of the wavelengths that they cannot absorb. All photosynthetic organisms contain a pigment called chlorophyll a, which humans see as the common green color associated with plants. Chlorophyll a absorbs wavelengths from either end of the visible spectrum (blue and red), but not from green. Because green is reflected, chlorophyll appears green. Other pigment types include chlorophyll b (which absorbs blue and red-orange light) and the carotenoids. Each type of pigment can be identified by the specific pattern of wavelengths it absorbs from visible light, which is its absorption spectrum. Many photosynthetic organisms have a mixture of pigments; between them, the organism can absorb energy from a wider range of visible-light wavelengths. Not all photosynthetic organisms have full access to sunlight. Some organisms grow underwater where light intensity decreases with depth, and certain wavelengths are absorbed by the water. Other organisms grow in competition for light. Plants on the rainforest floor must be able to absorb any bit of light that comes through, because the taller trees block most of the sunlight (Figure 5.11). Q: All photosynthetic organisms contain a pigment called what? Choices: - Fiber - carbonate - sodium - chlorophyll A:
(A).
chlorophyll
Ques:Answer the following question given this paragraph: Q: What term is used to describe the attractive force between molecules of the same substance? Choices: - magnetism - attraction - strength - cohesion A:

Ans:cohesion
Answer the following question given this paragraph: Iodine is added to alcohol and used as an antiseptic. It reacts with germs on cuts and wounds. Small amounts of iodine are also needed for good health. In the U. S. , iodine is added to table salt to prevent iodine deficiencies. Does the salt you use contain iodine?. Q: What is added to alcohol and used as an antiseptic? Choices: - chloride - arsenic - chlorine - iodine A:
iodine
