Answer the following question given this paragraph: Saturated and Unsaturated Fatty Acids. Saturated fatty acids include arachidic, stearic, and palmitic fatty acids. Unsaturated fatty acids include all the other fatty acids in the figure. Notice how all the unsaturated fatty acids have bent chains, whereas the saturated fatty acids have straight chains. Q: Arachidic, stearic, and palmitic fatty acids are examples of what type of fatty acid? Choices: - neutral - integral - compacted - saturated A:
saturated
Answer the following question given this paragraph: These birds are pairing up so that they can produce offspring. Many birds are monogamous , keeping the same mate for an entire season. In some species, they even stay paired for their entire life. Q: What term is used to describe birds that mate for an entire season or even stay paired for their entire life? Choices: - asexual - polygamous - homogeneous - monogamous A:
monogamous
Q: Answer the following question given this paragraph: 40.2 Components of the Blood Specific components of the blood include red blood cells, white blood cells, platelets, and the plasma, which contains coagulation factors and serum. Blood is important for regulation of the body's pH, temperature, osmotic pressure, the circulation of nutrients and removal of waste, the distribution of hormones from endocrine glands, and the elimination of excess heat; it also contains components for blood clotting. Red blood cells are specialized cells that contain hemoglobin and circulate through the body delivering oxygen to cells. White blood cells are involved in the immune response to identify and target invading bacteria, viruses, and other foreign organisms; they also recycle waste components, such as old red blood cells. Platelets and blood clotting factors cause the change of the soluble protein fibrinogen to the insoluble protein fibrin at a wound site forming a plug. Plasma consists of 90 percent water along with various substances, such as coagulation factors and antibodies. The serum is the plasma component of the blood without the coagulation factors. Q: Red blood cells, white blood cells, platelets, and plasma are all components of what fluid? Choices: - heart - brain - Vessals - blood A:
A: blood
Question: Answer the following question given this paragraph: The skin is the major organ of the integumentary system , which also includes the nails and hair. In fact, the skin is the body's largest organ, and a remarkable one at that. Consider these skin facts. The average square inch (6.5 cm 2 ) of skin has 20 blood vessels, 650 sweat glands, and more than a thousand nerve endings. It also has an incredible 60,000 pigment-producing cells. All of these structures are packed into a stack of cells that is just 2 mm thick, or about as thick as the cover of a book. Q: What organ system consists of the skin, nails and hair? Choices: - nervous system - digestive system - endocrine system - integumentary system A:
Answer: integumentary system

Answer the following question given this paragraph: The jointed appendages of arthropods may be used as legs for walking. Being jointed makes them more flexible. Try walking or climbing stairs without bending your knees, and you'll see why joints are helpful. In most arthropods, the appendages on the head have been modified for other functions. Figure below shows some of the head appendages found in arthropods. Sensory organs such as eyes are also found on the head. Q: What may the jointed appendages of arthropods be used for? Choices: - jumping - crawling - digging - walking A:
**Answer**
walking
Q: 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:
A: sperm
