Answer the following question given this paragraph: HIV spreads through contact between an infected person's body fluids and another person's bloodstream or mucus membranes, which are found in the mouth, nose, and genital areas. Body fluids that may contain HIV are blood, semen, vaginal fluid, and breast milk. The virus can spread through sexual contact or shared drug needles. It can also spread from an infected mother to her baby during childbirth or breastfeeding. Saliva can carry the HIV virus, but it won't spread it, unless the saliva gets into the bloodstream. Other body fluids such as urine and sweat do not contain the virus. HIV does not spread in any fluid in which the host cells cannot survive. Q: Saliva can carry the hiv virus, but it won't spread it, unless the saliva gets into what? Choices: - lungs - kidneys - liver - bloodstream A:
bloodstream

Answer the following question given this paragraph: Oceanographers use bathymetric maps to show the features of the bottom of a body of water. Q: What kind of map can show the features of the bottom of a body of water? Choices: - topographic - basic - country - bathymetric A:
(Answer)
bathymetric
Ques: Answer the following question given this paragraph: However, out of all this secrecy came several contributions to modern-day chemistry. Early acids and bases were discovered. Glassware for running chemical reactions was developed. Alchemy helped improve the study of metallurgy and the extraction of metals from ores. More systematic approaches to research were being developed, although the idea of orderly scientific experimentation had not become well-established yet. But the groundwork was laid to the development of chemistry as a foundational science. Q: Alchemy helped improve the study of metallurgy and the extraction of metals from what? Choices: - air - water - wood - ores A:
Ans: ores
(Q).
Answer the following question given this paragraph: Lipid-Derived Hormones (or Lipid-soluble Hormones) Most lipid hormones are derived from cholesterol and thus are structurally similar to it, as illustrated in Figure 37.2. The primary class of lipid hormones in humans is the steroid hormones. Chemically, these hormones are usually ketones or alcohols; their chemical names will end in "-ol" for alcohols or "-one" for ketones. Examples of steroid hormones include estradiol, which is an estrogen, or female sex hormone, and testosterone, which is an androgen, or male sex hormone. These two hormones are released by the female and male reproductive organs, respectively. Other steroid hormones include aldosterone and cortisol, which are released by the adrenal glands along with some other types of androgens. Steroid hormones are insoluble in water, and they are transported by transport proteins in blood. As a result, they remain in circulation longer than peptide hormones. For example, cortisol has a half-life of 60 to 90 minutes, while epinephrine, an amino acid derived-hormone, has a half-life of approximately one minute. Q: Most lipid hormones are derived from what? Choices: - protein - tissue - fat - cholesterol A:
(A).
cholesterol
Ques:Answer the following question given this paragraph: Work is done only if a force is exerted in the direction of motion. If the motion is perpendicular to the force, no work has been done. If the force is at an angle to the motion, then the component of the force in the direction of the motion is used to determine the work done. Q: Work is done only if a force is exerted in the direction of what? Choices: - wind - north - gravity - motion A:

Ans:motion
Ques: Answer the following question given this paragraph: Specifically, during cellular respiration, the energy stored in glucose is transferred to ATP ( Figure below ). ATP , or adenosine triphosphate, is chemical energy the cell can use. It is the molecule that provides energy for your cells to perform work, such as moving your muscles as you walk down the street. But cellular respiration is slightly more complicated than just converting the energy from glucose into ATP. Cellular respiration can be described as the reverse or opposite of photosynthesis. During cellular respiration, glucose, in the presence of oxygen, is converted into carbon dioxide and water. Recall that carbon dioxide and water are the starting products of photosynthesis. What are the products of photosynthesis?. Q: Cellular respiration is the reverse or opposite of what? Choices: - spermatogenesis - reproduction - glycolysis - photosynthesis A:
Ans:
photosynthesis
