Q: Q: In a transverse wave, the highest point the wave reaches is known as the?   Read this paragraph and choose the correct option from the provided answers:  In a transverse wave, particles of the medium move up and down at right angles to the direction of the wave. Wave amplitude of a transverse wave is the difference in height between the crest and the resting position. The crest is the highest point particles of the medium reach. The higher the crests are, the greater the amplitude of the wave.   Choices:  - flow  - valley  - axis  - crest   A:
A: crest


Q: Q: In what season are temperature inversions more common?   Read this paragraph and choose the correct option from the provided answers:  Sometimes air doesn’t mix in the troposphere. This happens when air is cooler close to the ground than it is above. The cool air is dense, so it stays near the ground. This is called a temperature inversion ( Figure below ). An inversion can trap air pollution near the surface. Temperature inversions are more common in the winter. Can you explain why?.   Choices:  - spring  - autumn  - summer  - winter   A:
A: winter


Q: Q: What is the functional unit of the kidney which actively filters blood and generates urine?   Read this paragraph and choose the correct option from the provided answers:  41.2 The Kidneys and Osmoregulatory Organs The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the osmolarity of body fluids at 300 mOsm. They are surrounded by three layers and are made up internally of three distinct regions—the cortex, medulla, and pelvis. The blood vessels that transport blood into and out of the kidneys arise from and merge with the aorta and inferior vena cava, respectively. The renal arteries branch out from the aorta and enter the kidney where they further divide into segmental, interlobar, arcuate, and cortical radiate arteries. The nephron is the functional unit of the kidney, which actively filters blood and generates urine. The nephron is made up of the renal corpuscle and renal tubule. Cortical nephrons are found in the renal cortex, while juxtamedullary nephrons are found in the renal cortex close to the renal medulla. The nephron filters and exchanges water and solutes with two sets of blood vessels and the tissue fluid in the kidneys. There are three steps in the formation of urine: glomerular filtration, which occurs in the glomerulus; tubular reabsorption, which occurs in the renal tubules; and tubular secretion, which also occurs in the renal tubules.   Choices:  - sechron  - epithelial  - mecrophron  - nephron   A:
A: nephron


Q: Q: What concept can be applied to biology, because the structure of an organism, or part of an organism, depends on its function?   Read this paragraph and choose the correct option from the provided answers:  An important concept in biology is that form follows function. In other words, the structure of an organism, or part of an organism, depends on its function. Apply this concept to plants, and explain why plants have different types of cells and tissues.   Choices:  - motion follows function  - attachment follows function  - form follows use  - form follows function   A:
