Answer the following question given this paragraph: Imagine the thrill of riding on a roller coaster like this one! The coaster slowly crawls to the top of the track and then flies down the other side. It also zooms around twists and turns at breakneck speeds. These changes in speed and direction are what make a roller coaster ride so exciting. Changes in speed or direction are called acceleration. Q: What is the term for changes in speed or direction, changes that make a roller coaster ride so exciting? Choices: - transmission - inclination - oscillation - acceleration A:
acceleration

Answer the following question given this paragraph: Fertilization Fertilization, pictured in Figure 43.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. The egg and sperm each contain one set of chromosomes. To ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. In mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. When a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. In placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma. Q: In mammals what does the zona pellucida protect? Choices: - testes - sperm - fetus - egg A:
(Answer)
egg

Ques:Answer the following question given this paragraph: There are 20 amino acids that make up proteins. With three bases per codon, there are 64 possible codons. This is more than enough to code for the 20 amino acids plus start and stop signals. You can see how to translate the genetic code in Figure below . Start at the center of the chart for the first base of each three-base codon. Then work your way out from the center for the second and third bases. Q: How many different amino acids make up proteins. Choices: - 14 - 25 - 30 - 20 A:

Ans:20
Ques: Answer the following question given this paragraph: Classification of Joints on the Basis of Function The functional classification divides joints into three categories: synarthroses, amphiarthroses, and diarthroses. A synarthrosis is a joint that is immovable. This includes sutures, gomphoses, and synchondroses. Amphiarthroses are joints that allow slight movement, including syndesmoses and symphyses. Diarthroses are joints that allow for free movement of the joint, as in synovial joints. Q: What category of joints is immovable? Choices: - amphiarthroses - sporozoans - diarthroses - synarthrosis A:
Ans:
synarthrosis
