Answer the following question given this paragraph: Noninfectious diseases are not contagious because they are not caused by pathogens. Instead, they are caused by such factors as lifestyle choices, environmental toxins, or mutations. Q: Why are noninfectious diseases not contagious? Choices: - they are contagious - they are viral - they are inherited - non-pathogen caused A:
non-pathogen caused

Answer the following question given this paragraph: 25.4 Microscopic Anatomy of the Kidney The functional unit of the kidney, the nephron, consists of the renal corpuscle, PCT, loop of Henle, and DCT. Cortical nephrons have short loops of Henle, whereas juxtamedullary nephrons have long loops of Henle extending into the medulla. About 15 percent of nephrons are juxtamedullary. The glomerulus is a capillary bed that filters blood principally based on particle size. The filtrate is captured by Bowman's capsule and directed to the PCT. A filtration membrane is formed by the fused basement membranes of the podocytes and the capillary endothelial cells that they embrace. Contractile mesangial cells further perform a role in regulating the rate at which the blood is filtered. Specialized cells in the JGA produce paracrine signals to regulate blood flow and filtration rates of the glomerulus. Other JGA cells produce the enzyme renin, which plays a central role in blood pressure regulation. The filtrate enters the PCT where absorption and secretion of several substances occur. The descending and ascending limbs of the loop of Henle consist of thick and thin segments. Absorption and secretion continue in the DCT but to a lesser extent than in the PCT. Each collecting duct collects forming urine from several nephrons and responds to the posterior pituitary hormone ADH by inserting aquaporin water channels into the cell membrane to fine tune water recovery. Q: What is a capillary bed that filters blood principally based on particle size? Choices: - buds - vein - plexus - glomerulus A:
(Answer)
glomerulus
Ques: Answer the following question given this paragraph: The digestive system consists of organs that break down food, absorb nutrients, and eliminate waste. Q: What body system consists of organs that break down food, absorb nutrients, and eliminate waste? Choices: - lymphatic system - hormonal system - skeletal system - digestive system A:
Ans: digestive system
(Q).
Answer the following question given this paragraph: Savannas Savannas are grasslands with scattered trees, and they are found in Africa, South America, and northern Australia (Figure 20.18). Savannas are hot, tropical areas with temperatures averaging from 24oC 29oC (75oF 84oF) and an annual rainfall of 51127 cm (2050 in). Savannas have an extensive dry season and consequent fires. As a result, scattered in the grasses and forbs (herbaceous flowering plants) that dominate the savanna, there are relatively few trees (Figure 20.20). Since fire is an important source of disturbance in this biome, plants have evolved well-developed root systems that allow them to quickly re-sprout after a fire. Q: What type of landscape has grasslands with scattered trees, are hot and have extensive dry seasons along with fire? Choices: - deserts - arctic - tundra - savannas A:
(A).
savannas
Ques:Answer the following question given this paragraph: There are only about 1,000 living species of gymnosperms, whereas there are hundreds of thousands of living species of angiosperms. Living gymnosperms are typically classified in the divisions described in the Table below . Most modern gymnosperms are trees with woody trunks. The majority are conifers such as pine trees. Q: The majoirty of modern gymnosperms belong to what group, which includes pine trees? Choices: - stems - Pinophytes - clusters - conifers A:

Ans:conifers
Ques:Answer the following question given this paragraph: Many of the higher neurological functions, such as memory, emotion, and consciousness, are the result of cerebral function. The complexity of the cerebrum is different across vertebrate species. The cerebrum of the most primitive vertebrates is not much more than the connection for the sense of smell. In mammals, the cerebrum comprises the outer gray matter that is the cortex (from the Latin word meaning "bark of a tree") and several deep nuclei that belong to three important functional groups. The basal nuclei are responsible for cognitive processing, the most important function being that associated with planning movements. The basal forebrain contains nuclei that are important in learning and memory. The limbic cortex is the region of the cerebral cortex that is part of the limbic system, a collection of structures involved in emotion, memory, and behavior. Q: The basal forebrain contains what that are important in learning and memory? Choices: - oxygen - ribosomes - atoms - nuclei A:

Ans:
nuclei
