Q: What is the term for a change in an object's motion, which occurs whenever an object is acted upon by an unbalanced force? Read this paragraph and choose the correct option from the provided answers: A change in an object's motionsuch as Xander speeding up on his scooteris called acceleration . Acceleration occurs whenever an object is acted upon by an unbalanced force. The greater the net force acting on the object, the greater its acceleration will be, but the mass of the object also affects its acceleration. The smaller its mass is, the greater its acceleration for a given amount of force. Newton's second law of motion summarizes these relationships. According to this law, the acceleration of an object equals the net force acting on it divided by its mass. This can be represented by the equation:. Choices: - rotation - compression - inclination - acceleration A:
(Answer)
acceleration

Ques: Q: What does bowman's capsule form by surrounding the glomerulus? Read this paragraph and choose the correct option from the provided answers: Renal Corpuscle As discussed earlier, the renal corpuscle consists of a tuft of capillaries called the glomerulus that is largely surrounded by Bowman's (glomerular) capsule. The glomerulus is a high-pressure capillary bed between afferent and efferent arterioles. Bowman's capsule surrounds the glomerulus to form a lumen, and captures and directs this filtrate to the PCT. The outermost part of Bowman's capsule, the parietal layer, is a simple squamous epithelium. It transitions onto the glomerular capillaries in an intimate embrace to form the visceral layer of the capsule. Here, the cells are not squamous, but uniquely shaped cells ( podocytes) extending finger-like arms ( pedicels) to cover the glomerular capillaries (Figure 25.11). These projections interdigitate to form filtration slits, leaving small gaps between the digits to form a sieve. As blood passes through the glomerulus, 10 to 20 percent of the plasma filters between these sieve-like fingers to be captured by Bowman's capsule and funneled to the PCT. Where the fenestrae (windows) in the glomerular capillaries match the spaces between the podocyte "fingers," the only thing separating the capillary lumen and the lumen of Bowman's capsule is their shared basement membrane (Figure 25.12). These three features comprise what is known as the filtration membrane. This membrane permits very rapid movement of filtrate from capillary to capsule though pores that are only 70 nm in diameter. Choices: - pores - ions - lipids - lumen A:
Ans: lumen

Q: What resource is considered nonrewable for human purposes, because it takes so long to form and is depleted by farming and other activities? Read this paragraph and choose the correct option from the provided answers: Although renewable, soil takes a very long to formup to hundreds of millions of years. So, for human purposes, soil is a nonrenewable resource. It is also constantly depleted of nutrients through careless use and eroded by wind and water. For example, misuse of soil caused a huge amount of it to simply blow away in the 1930s during the Dust Bowl (see Figure below ). Soil must be used wisely to preserve it for the future. Conservation practices include contour plowing and terracing. Both reduce soil erosion. Soil also must be protected from toxic wastes. Choices: - water - acid - sunshine - soil A:
(A).
soil

Ques:Q: Which is the least massive outer planet? Read this paragraph and choose the correct option from the provided answers: Uranus is the least massive outer planet. Its mass is only about 14 times the mass of Earth. Like all of the outer planets, Uranus is much less dense than Earth. Gravity is actually weaker than on Earth's surface. If you were at the top of the clouds on Uranus, you would weigh about 10 percent less than what you weigh on Earth. Choices: - venus - mars - jupiter - uranus A:

Ans:uranus

Q: Electromagnetic radiation behaves like particles as well as what? Read this paragraph and choose the correct option from the provided answers: Electromagnetic radiation behaves like particles as well as waves. This prompted Albert Einstein to develop his wave-particle theory. Choices: - fluids - currents - points - waves A:
waves
