Answer the following question given this paragraph: In saturated fatty acids, there are only single bonds between carbon atoms. As a result, the carbons are saturated with hydrogen atoms. Saturated fatty acids are found in fats. Fats are solid lipids that animals use to store energy. Q: What kind of bonds are there between carbon atoms in saturated fatty acids? Choices: - electrical - double - chemical - single A:
single
Answer the following question given this paragraph: Female Urethra The external urethral orifice is embedded in the anterior vaginal wall inferior to the clitoris, superior to the vaginal opening (introitus), and medial to the labia minora. Its short length, about 4 cm, is less of a barrier to fecal bacteria than the longer male urethra and the best explanation for the greater incidence of UTI in women. Voluntary control of the external urethral sphincter is a function of the pudendal nerve. It arises in the sacral region of the spinal cord, traveling via the S2S4 nerves of the sacral plexus. Q: The short length of what in women is the best explanation for the greater incidence of uti in women? Choices: - vagina - fallopian tube - uterus - urethra A:
urethra
Q: Answer the following question given this paragraph: Fiber is a complex carbohydrate that consists mainly of cellulose and comes only from plants. High-fiber foods include whole grains and legumes such as beans. Fiber can't be broken down by the digestive system, but it plays important roles in the body. It helps keep sugar and lipids at normal levels in the blood. It also helps keep food waste moist so it can pass easily out of the body. Q: What does fiber help keep at normal levels in the body? Choices: - salt and cholesterol - bloodpressure - hydration - sugar and lipids A:
A: sugar and lipids
Question: Answer the following question given this paragraph: 22.11 Algae Algae are much simpler than protozoa. They are aquatic and contain chlorophyll. Algae can exist as a single cell or as giant seaweeds 60 m in length. Formerly, algae were classified as plants but this was incorrect as algae lack parts of true plants: leaves, stems, roots, xylem, and phloem. Since algae belong in the kingdom Protista, algae is a broad term used to denote all aquatic eukaryotes which photosynthesise; algae can differ in size and shape as well. There are six phyla of algae:chlorophytes (green algae), phaeophytes (brown algae), rhodophytes (red algae), chrysophytes (diatoms), pyrrophytes (dinoflagellates), and euglenophytes (euglenoids). Q: Algae are much simpler than protozoa. they are aquatic and contain this? Choices: - testes - sporozoa - cloning factor - chlorophyll A:
Answer: chlorophyll

Answer the following question given this paragraph: Unlike a crystalline solid, an amorphous solid is a solid that lacks an ordered internal structure. Some examples of amorphous solids include rubber, plastic, and gels. Glass is a very important amorphous solid that is made by cooling a mixture of materials in such a way that it does not crystallize. Glass is sometimes referred to as a supercooled liquid rather than a solid. If you have ever watched a glassblower in action, you have noticed that he takes advantage of the fact that amorphous solids do not have a distinct melting point like crystalline solids do. Instead, as glass is heated, it slowly softens and can be shaped into all sorts of interesting forms. When a glass object shatters, it does so in a very irregular way, unlike crystalline solids, which always break into fragments that have the same shape as dictated by its crystal system. Q: Unlike a crystalline solid, an amorphous solid is a solid that lacks a what? Choices: - atoms - weight - color - ordered internal structure A:
**Answer**
ordered internal structure
(Q).
Answer the following question given this paragraph: Before lymph reaches the bloodstream, it passes through small oval structures called lymph nodes, which are located along the lymph vessels. Figure below shows where some of the body's many lymph nodes are concentrated. Lymph nodes act like filters and remove pathogens from lymph. Q: What act like filters and remove pathogens from lymph? Choices: - spine nodes - tissue nodes - electric nodes - lymph nodes A:
(A).
lymph nodes
