Answer the following question given this paragraph: 29.6 Mammals Mammals in general are vertebrates that possess hair and mammary glands. The mammalian integument includes various secretory glands, including sebaceous glands, eccrine glands, apocrine glands, and mammary glands. Mammals are synapsids, meaning that they have a single opening in the skull. A key characteristic of synapsids is endothermy rather than the ectothermy seen in other vertebrates. Mammals probably evolved from therapsids in the late Triassic period, as the earliest known mammal fossils are from the early Jurassic period. There are three groups of mammals living today: monotremes, marsupials, and eutherians. Monotremes are unique among mammals as they lay eggs, rather than giving birth to young. Eutherian mammals are sometimes called placental mammals, because all species possess a complex placenta that connects a fetus to the mother, allowing for gas, fluid, and nutrient exchange. Q: What makes monotremes different than other mammals? Choices: - they lack backbones - they spawn - they reproduce asexually - they lay eggs A:
they lay eggs

Answer the following question given this paragraph: Dialysis Technician Dialysis is a medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration. When kidney function fails, dialysis must be done to artificially rid the body of wastes. This is a vital process to keep patients alive. In some cases, the patients undergo artificial dialysis until they are eligible for a kidney transplant. In others who are not candidates for kidney transplants, dialysis is a life-long necessity. Dialysis technicians typically work in hospitals and clinics. While some roles in this field include equipment development and maintenance, most dialysis technicians work in direct patient care. Their on-the-job duties, which typically occur under the direct supervision of a registered nurse, focus on providing dialysis treatments. This can include reviewing patient history and current condition, assessing and responding to patient needs before and during treatment, and monitoring the dialysis process. Treatment may include taking and reporting a patient's vital signs and preparing solutions and equipment to ensure accurate and sterile procedures. Q: What is the medical process of removing wastes and excess water from the blood by diffusion and ultrafiltration called? Choices: - tumors - digestion - arthritis - dialysis A:
(Answer)
dialysis
Ques: Answer the following question given this paragraph: 26.3 Color and Color Vision The eye has four types of light receptorsrods and three types of color-sensitive cones. The rods are good for night vision, peripheral vision, and motion changes, while the cones are responsible for central vision and color. We perceive many hues, from light having mixtures of wavelengths. A simplified theory of color vision states that there are three primary colors, which correspond to the three types of cones, and that various combinations of the primary colors produce all the hues. The true color of an object is related to its relative absorption of various wavelengths of light. The color of a light source is related to the wavelengths it produces. Color constancy is the ability of the eye-brain system to discern the true color of an object illuminated by various light sources. The retinex theory of color vision explains color constancy by postulating the existence of three retinexes or image systems, associated with the three types of cones that are compared to obtain sophisticated information. Q: The four types of light receptors include different types of cones and what else? Choices: - quarks - neutrons - joints - rods A:
Ans: rods
(Q).
Answer the following question given this paragraph: The lunar surface has dark basalt maria. The light highlands are called terrae. Q: What are the light highlands of the moon called? Choices: - mariae - kepler hills - craters - terrae A:
(A).
terrae
Ques:Answer the following question given this paragraph: Carbohydrates are an important group of biological molecules that includes sugars and starches. Q: Carbohydrates are an important group of biological molecules that includes sugars and these? Choices: - fats - vitamins - proteins - starches A:

Ans:starches
Answer the following question given this paragraph: Fish have gills that allow them to "breathe" oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. Q: What do fish have that allow them to "breathe" oxygen in water? Choices: - lungs - layers - pores - gills A:
gills
