Q: What is another term for nearsightedness? Read this paragraph and choose the correct option from the provided answers: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. Choices: - hypoxia - astigmatism - anemia - myopia A:
myopia

Q: Which part of the axon has a higher membrane potential? Read this paragraph and choose the correct option from the provided answers: Choices: - muscular hillock - biofilm hillock - canals hillock - axon hillock A:
(Answer)
axon hillock

Ques: Q: What part of blood releases clotting factors? Read this paragraph and choose the correct option from the provided answers: Platelets ( Figure below ) are very small, but they are very important in blood clotting. Platelets are not cells. They are sticky little pieces of larger cells. Platelets bud off large cells that stay in the bone marrow. When a blood vessel gets cut, platelets stick to the injured areas. They release chemicals called clotting factors, which cause proteins to form over the wound. This web of proteins catches red blood cells and forms a clot. This clot stops more blood from leaving the body through the cut blood vessel. The clot also stops bacteria from entering the body. Platelets survive in the blood for ten days before they are removed by the liver and spleen. Choices: - hemoglobin - white blood cells - erythrocytes - platelets A:
Ans: platelets

Q: What is a process where some substances called reactants change chemically into different substances called products? Read this paragraph and choose the correct option from the provided answers: The student athlete in Figure below is practically flying down the track! Running takes a lot of energy. But you don't have to run a race to use energy. All living things need energy all the time just to stay alive. The energy is produced in chemical reactions. A chemical reaction is a process in which some substances, called reactants, change chemically into different substances, called products. Reactants and products may be elements or compounds. Choices: - crystals reaction - carbon reaction - non-chemical reaction - chemical reaction A:
(A).
chemical reaction

Ques:Q: What is the name of the muscular tube that carries urine out of the body? Read this paragraph and choose the correct option from the provided answers: From the collecting ducts of the kidneys, urine enters the ureters , two muscular tubes that move the urine by peristalsis to the bladder (see Figure above ). The bladder is a hollow, sac-like organ that stores urine. When the bladder is about half full, it sends a nerve impulse to a sphincter to relax and let urine flow out of the bladder and into the urethra. The urethra is a muscular tube that carries urine out of the body. Urine leaves the body through another sphincter in the process of urination . This sphincter and the process of urination are normally under conscious control. Choices: - rectum - uterus - bladder - urethra A:

Ans:urethra

Question: Q: In order to determine its molecular formula, it is necessary to know what about the compound? Read this paragraph and choose the correct option from the provided answers: Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds. In order to go from the empirical formula to the molecular formula, follow these steps:. Choices: - lipid mass - polar mass - protons mass - molar mass A:
Answer:
molar mass
