Ques: Q: What do you call the fragments of cells involved in the clotting process that are suspended in blood plasma? Read this paragraph and choose the correct option from the provided answers: Choices: - hematocrit - ironites - hemoglobin - platelets A:
Ans: platelets

Ques: Q: Saturn is made mostly of helium and what else? Read this paragraph and choose the correct option from the provided answers: Saturn's composition is similar to Jupiter's. The planet is made mostly of hydrogen and helium. These elements are gases in the outer layers and liquids in the deeper layers. Saturn may also have a small solid core. Saturn's upper atmosphere has clouds in bands of different colors. These clouds rotate rapidly around the planet. But Saturn has fewer storms than Jupiter. Thunder and lightning have been seen in the storms on Saturn ( Figure below ). Choices: - nitrogen - carbon - hydrogen - hydrogen A:
Ans: hydrogen

Ques: Q: What is the leading cause of death worldwide? Read this paragraph and choose the correct option from the provided answers: Heart: Coronary Artery Disease Coronary artery disease is the leading cause of death worldwide. It occurs when the buildup of plaquea fatty material including cholesterol, connective tissue, white blood cells, and some smooth muscle cellswithin the walls of the arteries obstructs the flow of blood and decreases the flexibility or compliance of the vessels. This condition is called atherosclerosis, a hardening of the arteries that involves the accumulation of plaque. As the coronary blood vessels become occluded, the flow of blood to the tissues will be restricted, a condition called ischemia that causes the cells to receive insufficient amounts of oxygen, called hypoxia. Figure 19.16 shows the blockage of coronary arteries highlighted by the injection of dye. Some individuals with coronary artery disease report pain radiating from the chest called angina pectoris, but others remain asymptomatic. If untreated, coronary artery disease can lead to MI or a heart attack. Choices: - lung disease - cancer - liver failure - coronary artery disease A:
Ans: coronary artery disease

Ques: Q: The force that a magnet exerts on certain materials is called what? Read this paragraph and choose the correct option from the provided answers: The force that a magnet exerts on certain materials, including other magnets, is called magnetic force . The force is exerted over a distance and includes forces of attraction and repulsion. North and south poles of two magnets attract each other, while two north poles or two south poles repel each other. A magnet can exert force over a distance because the magnet is surrounded by a magnetic field . In the Figure below , you can see the magnetic field surrounding a bar magnet. Tiny bits of iron, called iron filings, were placed under a sheet of glass. When the magnet was placed on the glass, it attracted the iron filings. The pattern of the iron filings shows the lines of force that make up the magnetic field of the magnet. The concentration of iron filings near the poles indicates that these areas exert the strongest force. You can also see how the magnetic field affects the compasses placed above the magnet.

Choices: - stellar force - velocity force - centripetal force - magnetic force A:
Ans:
