Ques:Q: What is the special name given to the diffusion of water through the cell membrane? Read this paragraph and choose the correct option from the provided answers: If a molecule can pass freely through a cell membrane, it will cross the membrane by diffusion ( Figure below ). The inside of the plasma membrane is hydrophobic, so certain molecules cannot easily pass through the membrane. Recall the semipermeable nature of the lipid bilayer. Molecules that cannot easily pass through the bilayer include ions and small hydrophilic molecules, such as glucose, and macromolecules, including proteins and RNA. Examples of molecules that can easily diffuse across the plasma membrane include carbon dioxide and oxygen gas. These molecules diffuse freely in and out of the cell, along their concentration gradient. Though water is a polar molecule, it can also diffuse through the plasma membrane. The diffusion of water through the cell membrane is of such importance to the cell that it is given a special name, osmosis . Choices: - hemostasis - passive transport - electrolysis - osmosis A:

Ans:osmosis

Ques:Q: Intestinal cells combine with proteins to create what? Read this paragraph and choose the correct option from the provided answers: Diffusion into intestinal cells, where they are combined with proteins to create chylomicrons. Choices: - amino acids - chondrocytes - lipoproteins - chylomicrons A:

Ans:chylomicrons

Ques:Q: The zeros at the end of a number are known as what? Read this paragraph and choose the correct option from the provided answers: Trailing zeros, which are zeros at the end of a number, are significant only if the number has a decimal point. Thus, in 1,500, the two trailing zeros are not. Choices: - rest zeros - edge zeros - remaining zeros - trailing zeros A:

Ans:trailing zeros

Ques:Q: What type of contamination causes almost 90% of diarrheal disease worldwide? Read this paragraph and choose the correct option from the provided answers: Unsafe water supplies have drastic effects on human health. Waterborne diseases are diseases due to microscopic pathogens in fresh water. These diseases can be caused by protozoa, viruses, bacteria, and intestinal parasites. In many parts of the world there are no water treatment plants. If sewage or animal manure gets into a river, then people downstream will get sick when they drink the water. According to the World Health Organization (WHO), diarrheal disease is responsible for the deaths of 1.8 million people every year. It was estimated that 88% of the cases of diarrheal disease are caused by unsafe water supplies. Choices: - air contamination - ground contamination - food contamination - water supply contamination A:

Ans:
water supply contamination
