Answer the following question given this paragraph: 27.1 | Anatomy and Physiology of the Male Reproductive System By the end of this section, you will be able to: Describe the structure and function of the organs of the male reproductive system Describe the structure and function of the sperm cell Explain the events during spermatogenesis that produce haploid sperm from diploid cells Identify the importance of testosterone in male reproductive function Unique for its role in human reproduction, a gamete is a specialized sex cell carrying 23 chromosomesone half the number in body cells. At fertilization, the chromosomes in one male gamete, called a sperm (or spermatozoon), combine with the chromosomes in one female gamete, called an oocyte. The function of the male reproductive system (Figure 27.2) is to produce sperm and transfer them to the female reproductive tract. The paired testes are a crucial component in this process, as they produce both sperm and androgens, the hormones that support male reproductive physiology. In humans, the most important male androgen is testosterone. Several accessory organs and ducts aid the process of sperm maturation and transport the sperm and other seminal components to the penis, which delivers sperm to the female reproductive tract. In this section, we examine each of these different structures, and discuss the process of sperm production and transport. Q: What is the male gamete called in humans? Choices: - dna - egg - testes - sperm A:
sperm

Answer the following question given this paragraph: Point source pollution enters water at just one place. For example, it might enter a stream through a pipe. Non-point source pollution enters water everywhere. It is carried by runoff. Q: At how many places does points source pollution enter water? Choices: - three - two - four - one A:
(Answer)
one

Answer the following question given this paragraph: An allergy occurs when the immune system attacks a harmless substance that enters the body from the outside. A substance that causes an allergy is called an allergen. It is the immune system, not the allergen, that causes the symptoms of an allergy. Q: What occurs when the immune system attacks a harmless substance that enters the body from the outside? Choices: - panic attack - nausea - plague - allergy A:
(A).
allergy
Ques:Answer the following question given this paragraph: Planets are held in their orbits by the force of gravity. What would happen without gravity? Imagine that you are swinging a ball on a string in a circular motion. Now let go of the string. The ball will fly away from you in a straight line. It was the string pulling on the ball that kept the ball moving in a circle. The motion of a planet is very similar to the ball on a string. The force pulling the planet is the pull of gravity between the planet and the Sun. Q: What force holds planets in their orbits? Choices: - magnetism - centrifuge - Big Bang - gravity A:

Ans:gravity
Answer the following question given this paragraph: Compressibility is the measure of how much a given volume of matter decreases when placed under pressure. If we put pressure on a solid or a liquid, there is essentially no change in volume. The atoms, ions, or molecules that make up the solid or liquid are very close together. There is no space between the individual particles, so they cannot pack together. Q: The measure of how much a given volume of matter decreases when placed under pressure is called? Choices: - elasticity - solubility - malleability - compressibility A:
compressibility
