Answer the following question given this paragraph: The Epithelial Cell Epithelial cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces. Particular structures found in some epithelial cells are an adaptation to specific functions. Certain organelles are segregated to the basal sides, whereas other organelles and extensions, such as cilia, when present, are on the apical surface. Cilia are microscopic extensions of the apical cell membrane that are supported by microtubules. They beat in unison and move fluids as well as trapped particles. Ciliated epithelium lines the ventricles of the brain where it helps circulate the cerebrospinal fluid. The ciliated epithelium of your airway forms a mucociliary escalator that sweeps particles of dust and pathogens trapped in the secreted mucous toward the throat. It is called an escalator because it continuously pushes mucous with trapped particles upward. In contrast, nasal cilia sweep the mucous blanket down towards your throat. In both cases, the transported materials are usually swallowed, and end up in the acidic environment of your stomach. Q: What cells are typically characterized by the polarized distribution of organelles and membrane-bound proteins between their basal and apical surfaces? Choices: - mast cells - nerve cells - connective tissue - epithelial cells A:
epithelial cells

Answer the following question given this paragraph: Electromagnetic waves may also be absorbed by matter and converted to other forms of energy. Microwaves are a familiar example. When microwaves strike food in a microwave oven, they are absorbed and converted to thermal energy, which heats the food. Q: Microwaves are converted into what kind of energy in a microwave oven? Choices: - solar energy - mechanical energy - light energy - thermal energy A:
(Answer)
thermal energy
Ques: Answer the following question given this paragraph: Type 2 diabetes occurs when body cells are no longer sensitive to insulin. The pancreas may still make insulin, but the cells of the body cannot use it efficiently. Being overweight and having high blood pressure increase the chances of developing type 2 diabetes. Type 2 diabetes usually develops in adulthood, but it is becoming more common in teens and children. This is because more young people are overweight, due to a high sugar and fat diet, now than ever before. Q: In what type of diabetes can the pancreas still make insulin, but the cells of the body cannot use it efficiently? Choices: - type 3 diabetes - type 1 diabetes - type A diabetes - type 2 diabetes A:
Ans: type 2 diabetes
(Q).
Answer the following question given this paragraph: Two DNA strands link together in an antiparallel direction and are twisted to form a double helix. The nitrogenous bases face the inside of the helix. Guanine is always opposite cytosine, and adenine is always opposite thymine. Q: What is formed when two dna strands link together in an antiparallel direction and are twisted? Choices: - guanine - anti-helix - RNA - double helix A:
(A).
double helix
Ques:Answer the following question given this paragraph: Figure 29.2 All chordates are deuterostomes possessing a notochord. Q: All chordates are deuterostomes possessing a what? Choices: - zygote - hydrochord - endoderm - notochord A:

Ans:notochord
Ques:Answer the following question given this paragraph: A mirror is typically made of glass with a shiny metal backing that reflects all the light that strikes it. When a mirror reflects light, it forms an image. An image is a copy of an object that is formed by reflection or refraction. Mirrors may have flat or curved surfaces. The shape of a mirror's surface determines the type of image it forms. For example, some mirrors form real images, and other mirrors form virtual images. What's the difference between real and virtual images?. Q: What is a copy of an image formed by reflection or refraction? Choices: - an example - a photographic image - a mirror image - an image A:

Ans:
an image
