Q: Often primary producers, what term describes species considered the "base" or "bedrock" of a community, having the greatest influence on its overall structure? Read this paragraph and choose the correct option from the provided answers: Foundation Species Foundation species are considered the "base" or "bedrock" of a community, having the greatest influence on its overall structure. They are often primary producers, and they are typically an abundant organism. For example, kelp, a species of brown algae, is a foundation species that forms the basis of the kelp forests off the coast of California. Foundation species may physically modify the environment to produce and maintain habitats that benefit the other organisms that use them. Examples include the kelp described above or tree species found in a forest. The photosynthetic corals of the coral reef also provide structure by physically modifying the environment (Figure 19.24). The exoskeletons of living and dead coral make up most of the reef structure, which protects many other species from waves and ocean currents. Choices: - fundamental - consumable - primary - foundation A:
foundation

Ques: Q: In many species, display behaviors, like a gorilla beating on its chest, are used instead of actual physical attacks to show what? Read this paragraph and choose the correct option from the provided answers: In many species, display behaviorsrather than actual physical attacksare used to show aggression. This helps prevent injury and death. Male gorillas, for example, are more likely to put on a display of aggression than to attack another male. In fact, gorillas have a whole series of display behaviors that they use to show aggression. They beat on their chest, dash back and forth, and pound the ground with their hands. Choices: - dominance - friction - stress - aggression A:

Ques:Q: Nitrogen wastes are produced by the breakdown of what during normal metabolism? Read this paragraph and choose the correct option from the provided answers: Regulation of Nitrogen Wastes Nitrogen wastes are produced by the breakdown of proteins during normal metabolism. Proteins are broken down into amino acids, which in turn are deaminated by having their nitrogen groups removed. Deamination converts the amino (NH2) groups into ammonia (NH3), ammonium ion (NH4+), urea, or uric acid (Figure 25.22). Ammonia is extremely toxic, so most of it is very rapidly converted into urea in the liver. Human urinary wastes typically contain primarily urea with small amounts of ammonium and very little uric acid. Choices: - enzymes - hormones - lipids - proteins A:

Ans:proteins

Ques: Q: What is the usual treatment for acute bronchitis? Read this paragraph and choose the correct option from the provided answers: Bronchitis is an inflammation of the bronchi, the air passages that conduct air into the lungs. The bronchi become red and swollen with infection. Acute bronchitis is usually caused by viruses or bacteria, and may last several days or weeks. It is characterized by a cough that produces phlegm, or mucus. Symptoms include shortness of breath and wheezing. Acute bronchitis is usually treated with antibiotics. Choices: - surgery - physical therapy - pesticides - antibiotics A:
Ans:
