Answer the following question given this paragraph: Sometimes people with an allergy get allergy shots. They are injected with tiny amounts of the allergen that triggers the allergic reaction. The shots are repeated at regular intervals, and the amount of allergen that is injected each time gradually increases. How do you think this might help an allergy? Do you think this approach just treats allergy symptoms or might it cure the allergy?. Q: What type of shots do people with allergy get? Choices: - nasal shots - booster shots - flu shots - allergy shots A:
allergy shots

Answer the following question given this paragraph: Protists are eukaryotes in the Protist Kingdom. Most are single-celled organisms. Protists are thought to be the oldest eukaryotes. They probably evolved when some prokaryotic cells invaded or were engulfed by others. Q: What is thought to be the oldest eukaryotes? Choices: - amoebas - prokaryotes - arthropods - protists A:
(Answer)
protists

Answer the following question given this paragraph: The Mucosal Immune Response Mucosal tissues are major barriers to the entry of pathogens into the body. The IgA (and sometimes IgM) antibodies in mucus and other secretions can bind to the pathogen, and in the cases of many viruses and bacteria, neutralize them. Neutralization is the process of coating a pathogen with antibodies, making it physically impossible for the pathogen to bind to receptors. Neutralization, which occurs in the blood, lymph, and other body fluids and secretions, protects the body constantly. Neutralizing antibodies are the basis for the disease protection offered by vaccines. Vaccinations for diseases that commonly enter the body via mucous membranes, such as influenza, are usually formulated to enhance IgA production. Immune responses in some mucosal tissues such as the Peyer's patches (see Figure 21.11) in the small intestine take up particulate antigens by specialized cells known as microfold or M cells (Figure 21.27). These cells allow the body to sample potential pathogens from the intestinal lumen. Dendritic cells then take the antigen to the regional lymph nodes, where an immune response is mounted. Q: What type of tissues are major barriers to the entry of pathogens into the body? Choices: - skin - vascular - nasal - mucosal A:
(A).
mucosal
Ques:Answer the following question given this paragraph: If energy cannot be destroyed, what happens to the energy that is absorbed in an endothermic reaction? The energy is stored in the chemical bonds of the products. This form of energy is called chemical energy. In an endothermic reaction, the products have more stored chemical energy than the reactants. In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants. The excess energy in the reactants is released to the surroundings when the reaction occurs. The graphs in Figure below show the chemical energy of reactants and products in each type of reaction. Q: What is one thing that can not happen to energy? Choices: - it cannot stay the same - it cannot increase - it cannot decrease - it can not be destroyed A:

Ans:it can not be destroyed
Ques:Answer the following question given this paragraph: A chemical change occurs whenever matter changes into an entirely different substance with different chemical properties. Burning is an example of a chemical change. Q: What kind of change occurs whenever matter changes into an entirely different substance with different chemical properties? Choices: - reversible change - physical change - carbon change - chemical change A:

Ans:
chemical change
