Answer the following question given this paragraph: Estuaries: Where the Ocean Meets Fresh Water Estuaries are biomes that occur where a river, a source of fresh water, meets the ocean. Therefore, both fresh water and salt water are found in the same vicinity; mixing results in a diluted (brackish) salt water. Estuaries form protected areas where many of the offspring of crustaceans, mollusks, and fish begin their lives. Salinity is an important factor that influences the organisms and the adaptations of the organisms found in estuaries. The salinity of estuaries varies and is based on the rate of flow of its freshwater sources. Once or twice a day, high tides bring salt water into the estuary. Low tides occurring at the same frequency reverse the current of salt water (Figure 20.30). Q: What are biomes that occur where a river, a source of fresh water, meets the ocean called? Choices: - waterways - sediments - rapids - estuaries A:
estuaries

Answer the following question given this paragraph: Did you notice that none of these statements relates to the identity of the gas? This means that all gases should behave similarly. A gas that follows these statements perfectly is called an ideal gas. Most gases show slight deviations from these statements and are called real gases. However, the existence of real gases does not diminish the importance of the kinetic theory of gases. One of the statements of the kinetic theory mentions collisions. As gas particles are constantly moving, they are also constantly colliding with each other and with the walls of their container. There are forces involved as gas particles bounce off the container walls (Figure 8.9 "Gas Pressure"). The force generated by gas particles divided by the. Q: Gases can be classifed as real or what? Choices: - noble - shape - dense - ideal A:
(Answer)
ideal
Ques: Answer the following question given this paragraph: Two forces may act on an object in the same direction. You can see an example of this in Figure below . After the man on the left lifts up the couch, he will push the couch to the right with a force of 25 newtons. At the same time, the man to the right is pulling the couch to the right with a force of 20 newtons. When two forces act in the same direction, the net force is equal to the sum of the forces. This always results in a stronger force than either of the individual forces alone. In this case, the net force on the couch is 45 newtons to the right, so the couch will move to the right. Q: What is the net force when two forces act in the same direction? Choices: - number of the forces - arguing forces - group of forces - sum of the forces A:
Ans: sum of the forces

Answer the following question given this paragraph: Try your hand at diagnosing an allergic reaction by selecting one of the interactive case studies (http://openstaxcollege. org/l/world_allergy) at the World Allergy Organization website. Autoimmunity Autoimmunity is a type of hypersensitivity to self-antigens that affects approximately five percent of the population. Most types of autoimmunity involve the humoral immune response. An antibody that inappropriately marks self-components as foreign is termed an autoantibody. In patients with myasthenia gravis, an autoimmune disease, muscle-cell receptors that induce contraction in response to acetylcholine are targeted by antibodies. The result is muscle weakness that may include. Q: What is the term for an antibody that inappropriately marks self-components as foreign? Choices: - rogue antibody - compromised antibody - autoimmune antibody - autoantibody A:
(A).
autoantibody
Ques:Answer the following question given this paragraph: Did you ever hear of hay fever? It's not really a fever at all. It's an allergy to plant pollens. People with this type of allergy have symptoms such as watery eyes, sneezing, and a runny nose. A common cause of hay fever is the pollen of ragweed. Many people are also allergic to poison ivy ( Figure below ). Skin contact with poison ivy leads to an itchy rash in people who are allergic to the plant. Q: Hay fever is actually an allergy to what substance, vital to plant reproduction? Choices: - nitrogen - fungi - grass - pollen A:

Ans:pollen
Ques: Answer the following question given this paragraph: Figure 22.31 The force on a current-carrying wire in a magnetic field is. Q: What is name of the phenomenon where similar traits evolve independently in species that do not share a common ancestry? Choices: - equation evolution - coalescence evolution - divergent evolution - convergent evolution A:
Ans:
convergent evolution
