Answer the following question given this paragraph: The cardiovascular system circulates blood through two different loops. Pulmonary circulation is a loop that carries blood between the heart and lungs. Systemic circulation is a loop that carries blood between the heart and the rest of the body. Q: What are the two loops of blood flow in the cardiovascular system? Choices: - anabolic and metabolic - aerobic and anaerobic - systolic and diastolic - pulmonary and systemic A:
pulmonary and systemic
Answer the following question given this paragraph: may not be able to use vision as their primary sense to find food. Instead, they are more likely to use taste or chemical cues to find prey. Wetlands Wetlands are environments in which the soil is either permanently or periodically saturated with water. Wetlands are different from lakes because wetlands are shallow bodies of water whereas lakes vary in depth. Emergent vegetation consists of wetland plants that are rooted in the soil but have portions of leaves, stems, and flowers extending above the water's surface. There are several types of wetlands including marshes, swamps, bogs, mudflats, and salt marshes (Figure 44.25). The three shared characteristics among these typeswhat makes them wetlandsare their hydrology, hydrophytic vegetation, and hydric soils. Q: There are several types of wetlands including marshes, swamps, bogs, mudflats, and salt marshes. the three shared characteristics among these typeswhat makes them wetlandsare their hydrology, hydrophytic vegetation, and this? Choices: - stibnite soils - sandy soils - niya soils - hydric soils A:
hydric soils
Q: Answer the following question given this paragraph: Summary By far the most abundant element in the universe is hydrogen. The fusion of hydrogen nuclei to form helium nuclei is the major process that fuels young stars such as the sun. Elements heavier than helium are formed from hydrogen and helium in the interiors of stars. Successive fusion reactions of helium nuclei at higher temperatures create elements with even numbers of protons and neutrons up to magnesium and then up to calcium. Eventually, the elements up to iron-56 and nickel-58 are formed by exchange processes at even higher temperatures. Heavier elements can only be made by a process that involves multiple neutron-capture events, which can occur only during the explosion of a supernova. Q: What is the most abundant element in the universe? Choices: - oxygen - helium - fluoride - hydrogen A:
A: hydrogen
Question: Answer the following question given this paragraph: When using a microscope we do not see the entire extent of the sample. Depending on the eyepiece and objective lens we see a restricted region which we say is the field of view. The objective is then manipulated in two-dimensions above the sample to view other regions of the sample. Electronic scanning of either the objective or the sample is used in scanning microscopy. The image formed at each point during the scanning is combined using a computer to generate an image of a larger region of the sample at a selected magnification. When using a microscope, we rely on gathering light to form an image. Hence most specimens need to be illuminated, particularly at higher magnifications, when observing details that are so small that they reflect only small amounts of light. To make such objects easily visible, the intensity of light falling on them needs to be increased. Special illuminating systems called condensers are used for this purpose. The type of condenser that is suitable for an application depends on how the specimen is examined, whether by transmission, scattering or reflecting. See Figure 26.20 for an example of each. White light sources are common and lasers are often used. Laser light illumination tends to be quite intense and it is important to ensure that the light does not result in the degradation of the specimen. Q: When using a microscope we do not see the entire extent of the sample. depending on the eyepiece and objective lens we see a restricted region which we say is this? Choices: - tunnel vision - focal point - peripheral view - field of view A:
Answer: field of view
