Answer the following question given this paragraph: 3.1 | Synthesis of Biological Macromolecules By the end of this section, you will be able to: Understand the synthesis of macromolecules Explain dehydration (or condensation) and hydrolysis reactions As you've learned, biological macromolecules are large molecules, necessary for life, that are built from smaller organic molecules. There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Combined, these molecules make up the majority of a cell's dry mass (recall that water makes up the majority of its complete mass). Biological macromolecules are organic, meaning they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, and additional minor elements. Q: The four major classes of biological macromolecules include carbohydrates, lipids, proteins, and what else? Choices: - liquids - fats - structural acids - nucleic acids A:
(Answer)
nucleic acids
Ques: Answer the following question given this paragraph: Characteristics of Blood When you think about blood, the first characteristic that probably comes to mind is its color. Blood that has just taken up oxygen in the lungs is bright red, and blood that has released oxygen in the tissues is a more dusky red. This is because hemoglobin is a pigment that changes color, depending upon the degree of oxygen saturation. Blood is viscous and somewhat sticky to the touch. It has a viscosity approximately five times greater than water. Viscosity is a measure of a fluid's thickness or resistance to flow, and is influenced by the presence of the plasma proteins and formed elements within the blood. The viscosity of blood has a dramatic impact on blood pressure and flow. Consider the difference in flow between water and honey. The more viscous honey would demonstrate a greater resistance to flow than the less viscous water. The same principle applies to blood. The normal temperature of blood is slightly higher than normal body temperatureabout 38 C (or 100.4 F), compared to 37 C (or 98.6 F) for an internal body temperature reading, although daily variations of 0.5 C are normal. Although. Q: What is the term for the measure of a fluid's thickness? Choices: - friction - elasticity - salinity - viscosity A:
Ans: viscosity

Answer the following question given this paragraph: The ideal gas law does not require that the properties of a gas change. Q: The ideal gas law does not require that the properties of what? Choices: - copper change - liquid change - transit change - gas change A:
(A).
gas change
Ques:Answer the following question given this paragraph: Plant Parasites Protist parasites of terrestrial plants include agents that destroy food crops. The oomycete Plasmopara viticola parasitizes grape plants, causing a disease called downy mildew (Figure 23.33). Grape plants infected with P. viticola appear stunted and have discolored, withered leaves. The spread of downy mildew nearly collapsed the French wine industry in the nineteenth century. Q: What disease is caused when the oomycete plasmopara viticola parasitizes grape plants? Choices: - dainty mildew - alkaline mildew - toxic mildew - downy mildew A:

Ans:downy mildew
Answer the following question given this paragraph: Human cells normally have two sets of chromosomes, one set inherited from each parent. There are 23 chromosomes in each set, for a total of 46 chromosomes per cell. Each chromosome in one set is matched by a chromosome of the same type in the other set, so there are actually 23 pairs of chromosomes per cell. Each pair consists of chromosomes of the same size and shape that also contain the same genes. The chromosomes in a pair are known as homologous chromosomes . Q: How many chromosomes are in each set? Choices: - 22 - 21 - 13 - 23 A:
23
