Answer the following question given this paragraph: Q: Vertical layering is an important feature of the terrestrial type of what kind of community? Choices: - habitat - environment - ecosystem - biome A:
biome
Answer the following question given this paragraph: Photosynthesis takes place in the organelle of the plant cell known as the chloroplasts. Chloroplasts are one of the main differences between plant and animal cells. Animal cells do not have chloroplasts, so they cannot photosynthesize. Photosynthesis occurs in two stages. During the first stage, the energy from sunlight is absorbed by the chloroplast. Water is used, and oxygen is produced during this part of the process. During the second stage, carbon dioxide is used, and glucose is produced. Q: What takes place in the organelle known as the chloroplast, which distinguishes animal from plant cells? Choices: - digestion - reproduction - perspiration - photosynthesis A:
photosynthesis
Q: Answer the following question given this paragraph: Lymph vessels make up a circulatory system that is similar to the cardiovascular system, which you can read about in a previous concept. Lymph vessels are like blood vessels, except they move lymph instead of blood. Lymph is a yellowish liquid that leaks out of tiny blood vessels into spaces between cells in tissues. Where there is more inflammation, there is usually more lymph in tissues. This lymph may contain many pathogens. Q: Lymph vessels are like blood vessels, except they move what instead of blood? Choices: - marrow - sperm - air - lymph A:
A: lymph
Question: Answer the following question given this paragraph: Archaea that produce methane are called methanogens. Q: Which gas is released by the group of archaea known as methanogens? Choices: - butane - propane - sulfur - methane A:
Answer: methane

Answer the following question given this paragraph: External Respiration The pulmonary artery carries deoxygenated blood into the lungs from the heart, where it branches and eventually becomes the capillary network composed of pulmonary capillaries. These pulmonary capillaries create the respiratory membrane with the alveoli (Figure 22.22). As the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter. Oxygenated hemoglobin is red, causing the overall appearance of bright red oxygenated blood, which returns to the heart through the pulmonary veins. Carbon dioxide is released in the opposite direction of oxygen, from the blood to the alveoli. Some of the carbon dioxide is returned on hemoglobin, but can also be dissolved in plasma or is present as a converted form, also explained in greater detail later in this chapter. External respiration occurs as a function of partial pressure differences in oxygen and carbon dioxide between the alveoli and the blood in the pulmonary capillaries. Q: The pulmonary artery carries deoxygenated blood into the lungs from this? Choices: - legs - bladder - brain - heart A:
**Answer**
heart
