Answer the following question given this paragraph: The two atoms that are held together in a covalent bond may be atoms of the same element or different elements. When atoms of different elements bond together, it forms a covalent compound. Q: What is formed when atoms of different elements bond together? Choices: - univalent compound - phenotype compound - duality compound - covalent compound A:
covalent compound
Answer the following question given this paragraph: Early vertebrates were ectothermic. Ectothermy means controlling body temperature to just a limited extent from the outside by changing behavior. For example, an ectotherm might stay in the shade to keep cool on a hot, sunny day. On a cold day, an ectotherm might bask in the sun to warm up, like the snake in Figure below . Almost all living fish, amphibians, and reptiles are ectothermic. They can raise or lower their body temperature by their behavior but not by very much. In cold weather, an ectotherm cools down. As its body temperature drops, its metabolism slows down and it becomes inactive. Q: What type of vertebrates control body temperature to just a limited extent from the outside by changing behavior? Choices: - etheric - endothermic - mimetic - ectothermic A:
ectothermic
Q: Answer the following question given this paragraph: Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). Q: Warming up your body before a workout does what to the blood flow? Choices: - reduces it - stops it - minimizes it - increases it A:
A: increases it
Question: Answer the following question given this paragraph: After food is digested, the resulting nutrients are absorbed. Absorption is the process in which substances pass into the bloodstream, where they can circulate throughout the body. Absorption of nutrients occurs mainly in the small intestine. Any remaining matter from food that cannot be digested and absorbed passes into the large intestine as waste. The waste later passes out of the body through the anus in the process of elimination . Q: What is the process called in which nutrients pass into the bloodstream? Choices: - accumulation - accumulation - incorporation - absorption A:
Answer: absorption

Answer the following question given this paragraph: Two different pathways accomplish the regeneration of NAD + with rather famous products: lactic acid (C 3 H 6 O 3 ) and ethyl alcohol (C 2 H 6 O) ( Figure above ). Making ATP in the absence of oxygen by glycolysis alone is known as fermentation . Therefore, these two pathways are called lactic acid fermentation and alcoholic fermentation . If you lack interest in organisms, such as yeast and bacteria, which have "stuck with" the anaerobic tradition, the products of these chemical reactions may still intrigue you. Fermentation makes bread, yogurt, beer, wine, and some new biofuels. In addition, some of your body's cells are facultative anaerobes, retaining one of these ancient pathways for short-term, emergency use. Q: In what process is atp created by glycolysis, without oxygen? Choices: - sedimentation - oxidation - condensation - fermentation A:
**Answer**
fermentation
Q: Answer the following question given this paragraph: Q: The effects of which kind of selection are larger than the effects of direct natural selection on individuals? Choices: - topical selection - stranger selection - unnatural selection - kin selection A:
A: kin selection
