Q: What types of energy is released during a chemical reaction? Read this paragraph and choose the correct option from the provided answers: All chemical reactions involve energy. Some chemical reactions consume energy, whereas other chemical reactions release energy. Chemical reactions can be either spontaneous, which do not require an input of energy, or non-spontaneous, which does require an input of some type of energy. Energy may be in the form of heat, light or electricity. Each of the energy changes that occur during a reaction are graphed in Figure below . In the reaction on the left, energy is released. In the reaction on the right, energy is consumed. Choices: - human, magnetic, electrical - temperature , electricity , light - magnetism, electricity, light - heat, electricity, light A:
heat, electricity, light

Q: The elbow is an example of a what type of joint? Read this paragraph and choose the correct option from the provided answers: Hinge Joints In hinge joints, the slightly rounded end of one bone fits into the slightly hollow end of the other bone. In this way, one bone moves while the other remains stationary, like the hinge of a door. The elbow is an example of a hinge joint. The knee is sometimes classified as a modified hinge joint (Figure 38.28). Choices: - pipe joint - toe joint - frame joint - hinge joint A:
hinge joint

Q: What do we call structures that are similar in related organisms because they were inherited from a common ancestor? Read this paragraph and choose the correct option from the provided answers: Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants. Figure below shows the hands of several different mammals. They all have the same basic pattern of bones. They inherited this pattern from a common ancestor. However, their forelimbs now have different functions. Choices: - monogamous - polylogous - filamentous - homologous A:
homologous

Q: What type of sti is characterized by blisters? Read this paragraph and choose the correct option from the provided answers: Genital herpes is a common STI caused by a herpes virus. The virus causes painful blisters on the penis or near the vaginal opening. The blisters generally go away on their own, but they may return repeatedly throughout life. There is no cure for genital herpes, but medicines can help prevent or shorten outbreaks. Choices: - syphilis - gonorrhea - chlamydia - genital herpes A:
