Answer the following question given this paragraph: Sperm are male gametes , or reproductive cells. When a male gamete meets a female gamete, they can form a new organism. Sperm form when certain cells in the male reproductive system divide by meiosis , resulting in cells with half the amount of DNA as a regular "body" cell. More precisely, sperm cells are haploid sex cells, having one set of chromosomes. Regular body cells are diploid, having two set of chromosomes. As there are 46 chromosomes in a diploid human cell, how many are in a human sperm cell?. Q: How many chromosomes are in a diploid human cell? Choices: - 46.63 chromosomes - 41 - 47 - 46 chromosomes A:
46 chromosomes

Ques:Answer the following question given this paragraph: Most of the visible light on Earth comes from the sun. The sun and other stars produce light because they are so hot. They glow with light due to their extremely high temperatures. This way of producing light is called incandescence . Incandescent light bulbs also produce light in this way. When electric current passes through a wire filament inside an incandescent bulb, the wire gets so hot that it glows. Do you see the glowing filament inside the incandescent light bulb in the Figure below ?. Q: The way in which the sun produces light is called what? Choices: - tumescence - rays - photosynthesis - incandescence A:

Ans:incandescence
