Answer the following question given this paragraph: When you get your cholesterol tested, they are measuring not only the total amount of cholesterol in the blood, but also whether it is being transported by LDL or HDL. All of these values are important for assessing the likelihood of a heart attack. Total cholesterol gives an idea of the overall cholesterol load in the body. The LDL cholesterol (sometimes referred to as "bad" cholesterol) is more likely to be incorporated into a cell or a plaque, so it is important that these levels below. Conversely, since cholesterol being carried by HDL ("good" cholesterol) is being transported away from the rest of the body and into the liver for disposal, higher HDL levels are generally considered beneficial. Q: What type of cholesterol is commonly referred to as bad? Choices: - unsaturated - hdl - insulin - ldl A:
ldl
Answer the following question given this paragraph: An electron is accelerated from rest through a potential difference of volts. It then enters a region traveling perpendicular to a magnetic field of . Calculate the velocity of the electron. Q: An electron is accelerated from rest through a potential difference of what? Choices: - joules - watts - amperes - volts A:
volts
Q: Answer the following question given this paragraph: Organs of the lymphatic system include the tonsils, thymus gland and spleen. The thymus gland produces T cells or T-lymphocytes (see below) and the spleen and tonsils help in fighting infections. The spleen's main function is to filter the blood. The spleen also detects viruses and bacteria and triggers the release of pathogen fighting cells. Q: What does the thymus gland produce? Choices: - b cells - insulin - hormones - t cells A:
A: t cells
Question: Answer the following question given this paragraph: Introduction Genetics is the study of heredity. Johann Gregor Mendel set the framework for genetics long before chromosomes or genes had been identified, at a time when meiosis was not well understood. Mendel selected a simple biological system and conducted methodical, quantitative analyses using large sample sizes. Because of Mendel's work, the fundamental principles of heredity were revealed. We now know that genes, carried on chromosomes, are the basic functional units of heredity with the ability to be replicated, expressed, or mutated. Today, the postulates put forth by Mendel form the basis of classical, or Mendelian, genetics. Not all genes are transmitted from parents to offspring according to Mendelian genetics, but Mendel's experiments serve as an excellent starting point for thinking about inheritance. Q: Introduction genetics is the study of what? Choices: - biology - variability - obesity - heredity A:
Answer: heredity

Answer the following question given this paragraph: 16.11 Energy in Waves: Intensity 17. Two identical waves undergo pure constructive interference. Is the resultant intensity twice that of the individual waves? Explain your answer. Circular water waves decrease in amplitude as they move away from where a rock is dropped. Explain why. Q: Circular water waves decrease in what property as they move away from where a rock is dropped? Choices: - voltage - frequency - mass - amplitude A:
**Answer**
amplitude
Answer the following question given this paragraph: There are three main ways that molecules can pass through a phospholipid membrane. The first way requires no energy input by the cell and is called passive transport. The second way requires that the cell uses energy to pull in or pump out certain molecules and ions and is called active transport. The third way is through vesicle transport, in which large molecules are moved across the membrane in bubble-like sacks that are made from pieces of the membrane. Q: How many different ways can molecules pass through a phospholipid membrane? Choices: - six - five - four - three A:
three
