Answer the following question given this paragraph: The second main component of plasma membranes are the variety of proteins. A membrane protein is a protein molecule that is attached to, or associated with the membrane of a cell or an organelle. Membrane proteins can be put into two groups based on how the protein is associated with the membrane: (1) integral membrane proteins and (2) peripheral membrane proteins. Q: What type of protein is a protein molecule that is attached to, or associated with the membrane of a cell or an organelle? Choices: - amino acid - rod protein - conduction protein - membrane protein A:
membrane protein

Answer the following question given this paragraph: Endocytosis is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane. The membrane folds over the substance and it becomes completely enclosed by the membrane. At this point a membrane-bound sac, or vesicle pinches off and moves the substance into the cytosol. There are two main kinds of endocytosis:. Q: What is the process of capturing a substance or particle from outside the cell by engulfing it with the cell membrane? Choices: - metastasis - autolysis - ectocytosis - endocytosis A:
(Answer)
endocytosis
Ques: Answer the following question given this paragraph: Food gives the body energy. You need energy for everything you do. The energy in food is measured in a unit called the Calorie. Q: What mainly gives the body energy? Choices: - water - sunlight - fuel - food A:
Ans: food
(Q).
Answer the following question given this paragraph: 7. Like the Richter scale, the moment magnitude scale is logarithmic. The 2011 Tohoku earthquake in Japan was 9.0 and did tremendous damage. A few months earlier, an 8.8 struck Chile and did much less damage. Why?. Q: What type of scale is the richter scale? Choices: - dimensional - algorithmic - asymmetric - logarithmic A:
(A).
logarithmic
Ques:Answer the following question given this paragraph: The ileocecal valve, a sphincter, is usually in a constricted state, but when motility in the ileum increases, this sphincter relaxes, allowing food residue to enter the first portion of the large intestine, the cecum. Relaxation of the ileocecal sphincter is controlled by both nerves and hormones. First, digestive activity in the stomach provokes the gastroileal reflex, which increases the force of ileal segmentation. Second, the stomach releases the hormone gastrin, which enhances ileal motility, thus relaxing the ileocecal sphincter. After chyme passes through, backward pressure helps close the sphincter, preventing backflow into the ileum. Because of this reflex, your lunch is completely emptied from your stomach and small intestine by the time you eat your dinner. It takes about 3 to 5 hours for all chyme to leave the small intestine. Q: The ileocecal valve, a sphincter, is usually in a constricted state, but when motility in the ileum increases, this sphincter relaxes, allowing food residue to enter the first portion of what? Choices: - small intestine - colon - liver - large intestine A:

Ans:large intestine
Ques: Answer the following question given this paragraph: mass, water should be a gas at room temperature (20C), but the strong intermolecular interactions in liquid water greatly increase its boiling point. Hydrogen bonding also produces the relatively open molecular arrangement found in ice, which causes ice to be less dense than water. Because ice floats on the surface of water, it creates an insulating layer that allows aquatic organisms to survive during cold winter months. These same strong intermolecular hydrogen-bonding interactions are also responsible for the high heat capacity of water and its high heat of fusion. A great deal of energy must be removed from water for it to freeze. Consequently, as noted in Chapter 5 "Energy Changes in Chemical Reactions", large bodies of water act as "thermal buffers" that have a stabilizing effect on the climate of adjacent land areas. Perhaps the most striking example of this effect is the fact that humans can live comfortably at very high latitudes. For example, palm trees grow in southern England at the same latitude (51N) as the southern end of frigid Hudson Bay and northern Newfoundland in North America, areas known more for their moose populations than for their tropical vegetation. Warm water from the Gulf Stream current in the Atlantic Ocean flows clockwise from the tropical climate at the equator past the eastern coast of the United States and then turns toward England, where heat stored in the water is released. The temperate climate of Europe is largely attributable to the thermal properties of water. Q: The thermal properties of what substance largely contribute to the temperature climate of europe? Choices: - lava - soil - clouds - water A:
Ans:
water
