Q: Answer the following question given this paragraph: After food is broken down into nutrient molecules, the molecules are absorbed by the blood. Absorption is the process in which nutrients or other molecules are taken up by the blood. Once absorbed by the blood, nutrients can travel in the bloodstream to cells throughout the body. Q: What type of fertilization do most reptiles use to reproduce? A:
Answer: internal

Problem:OPTIONS:
- producer
- predator
- consumer
- prey

Answer the following question given this paragraph: Q: Resemblance to other species can serve as protection to what category of species? A:
****
A: prey

Answer the following question given this paragraph: Receiving Electromagnetic Waves Electromagnetic waves carry energy away from their source, similar to a sound wave carrying energy away from a standing wave on a guitar string. An antenna for receiving EM signals works in reverse. And like antennas that produce EM waves, receiver antennas are specially designed to resonate at particular frequencies. An incoming electromagnetic wave accelerates electrons in the antenna, setting up a standing wave. If the radio or TV is switched on, electrical components pick up and amplify the signal formed by the accelerating electrons. The signal is then converted to audio and/or video format. Sometimes big receiver dishes are used to focus the signal onto an antenna. In fact, charges radiate whenever they are accelerated. When designing circuits, we often assume that energy does not quickly escape AC circuits, and mostly this is true. A broadcast antenna is specially designed to enhance the rate of electromagnetic radiation, and shielding is necessary to keep the radiation close to zero. Some familiar phenomena are based on the production of electromagnetic waves by varying currents. Your microwave oven, for example, sends electromagnetic waves, called microwaves, from a concealed antenna that has an oscillating current imposed on it. Q: What happens to charges whenever they are accelerated? A:
OPTIONS:
- they fuse
- they darken
- they die
- they radiate
they radiate

Answer the following question given this paragraph: No doubt you've had a sore throat before, and you've probably eaten cheese or yogurt. If so, then you've already encountered the amazing world of prokaryotes. Prokaryotes are single-celled organisms that lack a nucleus. They also lack other membrane-bound organelles. Prokaryotes are tiny. They can only be viewed with a microscope (see Figure below ). But they are the most numerous organisms on Earth. Without them, the world would be a very different place. Q: What is a feature that prokaryotes lack? A:
OPTIONS:
- epidermis
- cell wall
- plasma
- nucleus

Answer: nucleus

Question: Answer the following question given this paragraph: Chapter 21 1 The three main components are the lymph vessels, the lymph nodes, and the lymph. 3 The bacterium is digested by the phagocyte's digestive enzymes (contained in its lysosomes). 5 B 7 C 9 A 11 D 13 C 15 B 17 B 19 D 21 D 23 B 25 C 27 B 29 C 31 D 33 A 35 B 37 B 39 The lymph enters through lymphatic capillaries, and then into larger lymphatic vessels. The lymph can only go in one direction due to valves in the vessels. The larger lymphatics merge to form trunks that enter into the blood via lymphatic ducts. 41 Interferons are produced in virally infected cells and cause them to secrete signals for surrounding cells to make antiviral proteins. C-reactive protein is induced to be made by the liver and will opsonize certain species of bacteria. 43 Antigen-specific clones are stimulated as their antigen receptor binds to antigen. They are then activated and proliferate, expanding their numbers. The result is a large number of antigen-specific lymphocytes. 45 IgM is an antigen receptor on naive B cells. Upon activation, naive B cells make IgM first. IgM is good at binding complement and thus has good antibacterial effects. IgM is replaced with other classes of antibodies later on in the primary response due to class switching. 47 Tuberculosis is caused by bacteria resistant to lysosomal enzymes in alveolar macrophages, resulting in chronic infection. The immune response to these bacteria actually causes most of the lung damage that is characteristic of this life-threatening disease. 49 Antibody response to the cell walls of -Streptococcus cross-reacts with the heart muscle. Complement is then activated and the heart is damaged, leading to abnormal function. Tolerance is broken because heart myosin antigens are similar to antigens on the - Streptococcus bacteria. Q: Interferons are produced in virally infected cells and cause them to secrete signals for surrounding cells to make what? A:
OPTIONS:
- overwhelm proteins
- resist proteins
- Raising Proteins
- antiviral proteins
Answer: antiviral proteins

input: OPTIONS:
- fuel chain
- dependent chain
- water cycle
- food chain Now, answer this question: Answer the following question given this paragraph: A food chain is a simple diagram that shows one way energy flows through an ecosystem. Pictured below is an example of a food chain ( Figure below ). Producers form the base of all food chains. The consumers that eat producers are called primary consumers. The consumers that eat primary consumers are secondary consumers. This chain can continue to multiple levels. Q: What is a diagram that shows a single way that energy flows throughout an ecosystem? A:
A:
output:
food chain
