Ques: Q: What are the tiny, tube-shaped structures found inside a kidney called? Read this paragraph and choose the correct option from the provided answers: There are many blood vessels in the kidneys ( Figure above ). The kidneys remove urea and other wastes from the blood through tiny filtering units called nephrons. Nephrons ( Figure below ) are tiny, tube-shaped structures found inside each kidney. Each kidney has up to a million nephrons. Each nephron collects a small amount of fluid and waste from a small group of capillaries. Choices: - neurons - jejunum - dendrites - nephrons A:
Ans: nephrons

(Q).
Q: What substances that primarily comprise plasma membranes form a bilayer? Read this paragraph and choose the correct option from the provided answers: Plasma membranes are primarily made up of phospholipids (orange). The hydrophilic ("water-loving") head and two hydrophobic ("water-hating") tails are shown. The phospholipids form a bilayer (two layers). The middle of the bilayer is an area without water. There can be water on either side of the bilayer. There are many proteins throughout the membrane. Choices: - amino acids - enzymes - steroids - phospholipids A:
(A).
phospholipids

Ques:Q: What is the term for water that falls from clouds? Read this paragraph and choose the correct option from the provided answers: Precipitation is water that falls from clouds. It may fall as liquid or frozen water. Types of frozen precipitation include snow, sleet, freezing rain, and hail. Choices: - lightning - atmosphere - wind - precipitation A:

Ans:precipitation

Q: What are the simplest hydrocarbons? Read this paragraph and choose the correct option from the provided answers: Saturated hydrocarbons contain only single bonds between carbon atoms. They are the simplest hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in Figure below . Each carbon atom is bonded to three hydrogen atoms in this compound, which is named ethane. Choices: - unsaturated hydrocarbons - complex carbohydrates - fossil fuels - saturated hydrocarbons A:
saturated hydrocarbons
