Answer the following question given this paragraph: One end of each phospholipid molecule is polar, so it has a partial electric charge. Water is also polar and has electrically charged ends, so it is attracted to the oppositely charged end of a phospholipid molecule. This end of the phospholipid molecule is described as hydrophilic, which means "water loving. ". Q: Water is polar and has electrically charged ends, so it is attracted to the oppositely charged end of a phospholipid molecule, which is described by what term meaning "water-loving"? Choices: - aqueous - hydrophobic - cytosolic - hydrophilic A:
(Answer)
hydrophilic
Ques: Answer the following question given this paragraph: Opening Essay On July 11, 2003, the Food and Drug Administration amended its food labeling regulations to require that manufacturers list the amount of trans fatty acids on Nutrition Facts labels of foods and dietary supplements, effective January 1, 2006. This amendment was a response to published studies demonstrating a link between the consumption of trans fatty acids and an increased risk of heart disease. Trans fatty acids are produced in the conversion of liquid oils to solid fats, as in the creation of many commercial margarines and shortenings. They have been shown to increase the levels of low-density lipoproteins (LDLs)complexes that are often referred to as bad cholesterolin the blood. In this chapter, you will learn about fatty acids and what is meant by a trans fatty acid, as well as the difference between fats and oils. You will also learn what cholesterol is and why it is an important molecule in the human body. Fats and oils, found in many of the foods we eat, belong to a class of biomolecules known as lipids. Gram for gram, they pack more than twice the caloric content of carbohydrates: the oxidation of fats and oils supplies about 9 kcal of energy for every gram oxidized, whereas the oxidation of carbohydrates supplies only 4 kcal/g. Although the high caloric content of fats may be bad news for the dieter, it says something about the efficiency of nature's designs. Our bodies use carbohydrates, primarily in the form of glucose, for our immediate energy needs. Our capacity for storing carbohydrates for later use is limited to tucking away a bit of glycogen in the liver or in muscle tissue. We store our reserve energy in lipid form, which requires far less space than the same amount of energy stored in carbohydrate form. Lipids have other biological functions besides energy storage. They are a major component of the membranes of the 10 trillion cells in our bodies. They serve as. Q: Our bodies use what, primarily in the form of glucose, for our immediate energy needs - although they are not as energy dense or capable of long-term storage as lipids? Choices: - enzymes - electrolytes - proteins - carbohydrates A:
Ans: carbohydrates

Answer the following question given this paragraph: Electromagnetic waves are waves that carry energy through matter or space as vibrating electric and magnetic fields. Electromagnetic waves have a wide range of wavelengths and frequencies. Sunlight contains the complete range of wavelengths of electromagnetic waves, which is called the electromagnetic spectrum. The Figure below shows all the waves in the spectrum. Q: What type of waves carry energy through matter or space as vibrating electric and magnetic fields? Choices: - light waves - mechanical waves - sound waves - electromagnetic waves A:
(A).
electromagnetic waves
Ques:Answer the following question given this paragraph: Neptune's appearance changes due to its turbulent atmosphere. Winds are stronger than on any other planet in the solar system. Wind speeds can reach 1,100 km/h (700 mph). This is close to the speed of sound! The rapid winds surprised astronomers. This is because Neptune receives little energy from the Sun to power weather systems. It is not surprising that Neptune is one of the coldest places in the solar system. Temperatures at the top of the clouds are about 218C (360F). Q: Why does neptune's appearance change? Choices: - the seasons - the changing orbit - the speed of rotation - turbulent atmosphere A:

Ans:turbulent atmosphere
Question: Answer the following question given this paragraph: Following the discovery of the electron, J. J. Thomson developed what became known as the " plum pudding " model in 1904. Plum pudding is an English dessert similar to a blueberry muffin. In Thomson's plum pudding model of the atom, the electrons were embedded in a uniform sphere of positive charge like blueberries stuck into a muffin. The positive matter was thought to be jelly- like or a thick soup. The electrons were somewhat mobile. As they got closer to the outer portion of the atom, the positive charge in the region was greater than the neighboring negative charges and the electron would be pulled back more toward the center region of the atom. Q: Thomson's plum pudding model shows the structure of what? Choices: - nucleus - cell - DNA - atom A:
Answer:
atom
