Answer the following question given this paragraph: Colon The cecum blends seamlessly with the colon. Upon entering the colon, the food residue first travels up the ascending colon on the right side of the abdomen. At the inferior surface of the liver, the colon bends to form the right colic flexure (hepatic flexure) and becomes the transverse colon. The region defined as hindgut begins with the last third of the transverse colon and continues on. Food residue passing through the transverse colon travels across to the left side of the abdomen, where the colon angles sharply immediately inferior to the spleen, at the left colic flexure (splenic flexure). From there, food residue passes through the descending colon, which runs down the left side of the posterior abdominal wall. After entering the pelvis inferiorly, it becomes the s-shaped sigmoid colon, which extends medially to the midline (Figure 23.21). The ascending and descending colon, and the rectum (discussed next) are located in the retroperitoneum. The transverse and sigmoid colon are tethered to the posterior abdominal wall by the mesocolon. Q: What organ is subdivided into ascending, descending, transverse and sigmoid parts? Choices: - heart - uterus - lungs - colon A:
colon

Answer the following question given this paragraph: Light may interact with matter in several ways, including reflection, refraction, transmission, and absorption. Matter can be classified on the basis of how light interacts with it as transparent, translucent, or opaque. Q: What are the three ways to classify matter based on how light interacts with it? Choices: - opaque, invisible, visible - transitive, opaque, translucent - extensive , opaque , translucent - transparent, opaque, translucent A:
(Answer)
transparent, opaque, translucent

Ques:Answer the following question given this paragraph: Some materials have negative heats of solution; the dissolution of one of these solutes in water is an exothermic process. Heat is released, causing a net increase in the temperature of the solution. Conversely, other substances have positive heats of solution. For example, the dissolution of potassium nitrate in water is an endothermic process. The resulting absorption of energy causes the solution to become colder. Calculations involving heats of solutions follow the same basic approach that we have used with other enthalpy problems. Q: Some materials have negative heats of solution; the dissolution of one of these solutes in water is called? Choices: - endothermic process - acetylene process - ionized process - exothermic process A:

Ans:exothermic process
Answer the following question given this paragraph: 15.5 Echinoderms and Chordates Echinoderms are deuterostome marine organisms. This phylum of animals bear a calcareous endoskeleton composed of ossicles covered by a spiny skin. Echinoderms possess a water-based circulatory system. The madreporite is the point of entry and exit for water for the water vascular system. The characteristic features of Chordata are a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets), together with the. Q: What kind of system do echinoderms possess? Choices: - primitive respiratory - autonomic nerous system - photosynthetic - water-based circulatory A:
water-based circulatory
