Answer the following question given this paragraph: Animals not only have specialized cells. Most animals also have tissues and organs. In many animals, organs form organ systems, such as a nervous system. Higher levels of organization allow animals to perform many complex functions. What can animals do that most other living things cannot? Here are some examples. All of them are illustrated in Figure below . Q: Groups of related organs form what? Choices: - community systems - maturation systems - artificial systems - organ systems A:
organ systems
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
Q: Answer the following question given this paragraph: Q: Androgen secretion and sperm production are both controlled by hypothalamic and which other hormones? Choices: - Testes - salivary - adrenal - pituitary A:
A: pituitary
Question: Answer the following question given this paragraph: The main function of the cardiovascular system is transporting substances around the body. Figure above shows some of the substances that are transported in the blood. They include hormones, oxygen, nutrients from digested food, and cellular wastes. Transport of all these materials is necessary to maintain homeostasis of the body and life itself. Q: What is the main function of the cardiovascular system? Choices: - respiration of air - excretion of food waste - coordinate bones and muscles - transporting substances around the body A:
Answer: transporting substances around the body

Answer the following question given this paragraph: Fluid friction is friction that acts on objects that are moving through a fluid. A fluid is a substance that can flow and take the shape of its container. Fluids include liquids and gases. If you've ever tried to push your open hand through the water in a tub or pool, then you've experienced fluid friction between your hand and the water. When a skydiver is falling toward Earth with a parachute, fluid friction between the parachute and the air slows the descent (see Figure below ). Fluid pressure with the air is called air resistance. The faster or larger a moving object is, the greater is the fluid friction resisting its motion. The very large surface area of a parachute, for example, has greater air resistance than a skydiver's body. Q: What two states of matter are included in the category "fluids"? Choices: - solids and gases - bacteria and gases - liquids and soilds - liquids and gases A:
(Answer)
liquids and gases
