Answer the following question given this paragraph: 20.3 | Capillary Exchange By the end of this section, you will be able to: Identify the primary mechanisms of capillary exchange Distinguish between capillary hydrostatic pressure and blood colloid osmotic pressure, explaining the contribution of each to net filtration pressure Compare filtration and reabsorption Explain the fate of fluid that is not reabsorbed from the tissues into the vascular capillaries The primary purpose of the cardiovascular system is to circulate gases, nutrients, wastes, and other substances to and from the cells of the body. Small molecules, such as gases, lipids, and lipid-soluble molecules, can diffuse directly through the membranes of the endothelial cells of the capillary wall. Glucose, amino acids, and ionsincluding sodium, potassium, calcium, and chlorideuse transporters to move through specific channels in the membrane by facilitated diffusion. Glucose, ions, and larger molecules may also leave the blood through intercellular clefts. Larger molecules can pass through the pores of fenestrated capillaries, and even large plasma proteins can pass through the great gaps in the sinusoids. Some large proteins in blood plasma can move into and out of the endothelial cells packaged within vesicles by endocytosis and exocytosis. Water moves by osmosis. Q: How do glucose, ions, and other larger molecules leave the blood? Choices: - through cell membranes - through capillary tips - through veinous fissures - through intercellular clefts A:
through intercellular clefts

in red marrow
Ques: Answer the following question given this paragraph: One of the first uses of rockets in space was to launch satellites. A satellite is an object that orbits a larger object. An orbit is a circular or elliptical path around an object. Natural objects in orbit are called natural satellites. The Moon is a natural satellite. Human-made objects in orbit are called artificial satellites. There are more and more artificial satellites orbiting Earth all the time. They all get into space using some sort of rocket. Q: What is an object that orbits a larger object called? Choices: - asteroid - meteorite - comet - satellite A:
Ans: satellite
(Q).
Answer the following question given this paragraph: Q: Common among mammals and insects, pheromones are often related to what type of behavior? Choices: - aggressive - immune - cardiac - reproductive A:
(A).
reproductive
Ques:Answer the following question given this paragraph: It is estimated that 100 trillion bacteria live in the gut. This is more than the human cells that make up you. It has also been estimated that there are more bacteria in your mouth than people on the planet. There are over 7 billion people on the planet. Q: An estimated 100 trillion of these live in the gut of an average person? Choices: - viruses - pathogens - algae - bacteria A:

Ans:bacteria
Question: Answer the following question given this paragraph: Coral reefs ( Figure below ) look like big rocks, but they are actually alive. They are built from cnidarians called corals. The corals are sessile (non-moving) polyps that can use their tentacles to feed on ocean creatures that pass by. Their skeletons are made up of calcium carbonate, which is also known as limestone. Over long periods of time, their skeletons build on each other to produce large structures known as coral reefs. Coral reefs are important habitats for many different types of ocean life. Q: Although they look like big rocks, what structures that serve as habitats for many different types of ocean life are actually alive? Choices: - new forming reefs - natural reefs - southern reefs - coral reefs A:
Answer:
coral reefs
