Q: Q: What group of gases are unusually unreactive? Read this paragraph and choose the correct option from the provided answers: Nonmetals tend to gain electrons in chemical reactions and have a high attraction to electrons within a compound. The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are an unusually unreactive group, the element fluorine is the most reactive nonmetal. It is also not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. Choices: - volcanic gases - greenhouse gases - halogens - noble gases A:
A: noble gases

Q: Q: What are the two components of the autonomic nervous system? Read this paragraph and choose the correct option from the provided answers: 31.3 Peripheral nervous system The peripheral nervous system is broken down into two sub-systems, the somatic nervous system and the autonomic nervous system. ANS - Autonomic Nervous System The ANS has two components - parasympathetic and sympathetic. The sympathetic nervous system is the "fight or flight" or fright response and results in an increased heart rate, increased rate of breathing, and an elevated blood glucose level. There is also decreased digestion. The second neurotransmitter is epinephrine. In this case, the first neuron is short and the second neuron is long. The parasympathetic nervous system is the rest and digest system. Drugs must be able to pass the blood brain barrier to have an effect on the CNS. Drugs act by affecting the neuron and how likely it is to fire an action potential. Stroke occurs when there is a blood clot that goes to the brain and prevent blood flow. Choices: - empathetic and sympathetic - crystallisation and sympathetic - neurons and sympathetic - parasympathetic and sympathetic A:
A: parasympathetic and sympathetic

Q: Q: What term is used to describe birds that mate for an entire season or even stay paired for their entire life? Read this paragraph and choose the correct option from the provided answers: These birds are pairing up so that they can produce offspring. Many birds are monogamous , keeping the same mate for an entire season. In some species, they even stay paired for their entire life. Choices: - asexual - polygamous - homogeneous - monogamous A:
A: monogamous

Q: Q: How do fungus-like protists such as slime molds reproduce? Read this paragraph and choose the correct option from the provided answers: Fungus-like protists are molds. They are absorptive feeders, found on decaying organic matter. They resemble fungi and reproduce with spores as fungi do. Examples of fungus-like protists include slime molds and water molds. Choices: - photosynthesis - sexually - asexually - with spores A:
A: with spores
