Answer the following question given this paragraph: What is one of the most important characteristics of a referee? A referee must be neutral. He can't favor one team over the other. In chemistry, being neutral means not being an acid or a base. Pure water is an example of a neutral substance. In some chemical reactions, an acid and a base combine to form neutral products, including water. You'll see how this happens when you read this article. Q: What do you call a substance that is not an acid or a base? Choices: - equivalent - toxic - oxidic - neutral A:
neutral

Answer the following question given this paragraph: capillaries cause swelling of the area, which in turn causes pain. Various kinds of white blood cells are attracted to the area of inflammation. The types of white blood cells that arrive at an inflamed site depend on the nature of the injury or infecting pathogen. For example, a neutrophil is an early arriving white blood cell that engulfs and digests pathogens. Neutrophils are the most abundant white blood cells of the immune system (Figure 17.9). Macrophages follow neutrophils and take over the phagocytosis function and are involved in the resolution of an inflamed site, cleaning up cell debris and pathogens. Q: The types of white blood cells that arrive at an inflamed site depend on the nature of what? Choices: - genes - skin color - blood type - injury or infection A:
(Answer)
injury or infection
Ques: Answer the following question given this paragraph: The other idea is that evolution occurs by natural selection . Natural selection is the process that results in living things with beneficial traits producing more offspring than others. This results in changes in the traits of living things over time. Q: What is the process resulting in living things with beneficial traits producing more offspring? Choices: - fluid selection - Natural choice. - natural change - natural selection A:
Ans: natural selection

Answer the following question given this paragraph: The science of how living things interact with each other and their environment is called ecology. Ecology is a major branch of life science, but it overlaps with many other fields. For example, it shares data and theories with geography, biology, climatology, and other sciences. In this lesson, you'll learn some of the basic concepts of ecology. Q: What is the science of how living things interact with each other and their environment? Choices: - zoology - biology - compatibility - ecology A:
(A).
ecology
Ques:Answer the following question given this paragraph: This timeline shows the history of life on Earth. In the entire span of the time, humans are a relatively new addition. Q: Are humans a new or old species on the earth? Choices: - primal - old - extinct - new A:

Ans:new
Question: Answer the following question given this paragraph: Motility The majority of protists are motile, but different types of protists have evolved varied modes of movement (Figure 23.8). Some protists have one or more flagella, which they rotate or whip. Others are covered in rows or tufts of tiny cilia that they coordinately beat to swim. Still others form cytoplasmic extensions called pseudopodia anywhere on the cell, anchor the pseudopodia to a substrate, and pull themselves forward. Some protists can move toward or away from a stimulus, a movement referred to as taxis. Movement toward light, termed phototaxis, is accomplished by coupling their locomotion strategy with a light-sensing organ. Q: What is the term for movement toward light? Choices: - phototropism - gravitational pull - autolysis - phototaxis A:
Answer:
phototaxis
