Answer the following question given this paragraph: Introduction All life on Earth is related. Evolutionary theory states that humans, beetles, plants, and bacteria all share a common ancestor, but that millions of years of evolution have shaped each of these organisms into the forms seen today. Scientists consider evolution a key concept to understanding life. Natural selection is one of the most dominant evolutionary forces. Natural selection acts to promote traits and behaviors that increase an organism's chances of survival and reproduction, while eliminating those traits and behaviors that are to the organism's detriment. But natural selection can only, as its name implies, selectit cannot create. The introduction of novel traits and behaviors falls on the shoulders of another evolutionary forcemutation. Mutation and other sources of variation among individuals, as well as the evolutionary forces that act upon them, alter populations and species. This combination of processes has led to the world of life we see today. Q: Natural selection cannot create new variations in organisms - these new variations must be created by what, which are usually associated with some sort of abnormality? Choices: - radiation - infection - pollution - mutation A:
(Answer)
mutation

Answer the following question given this paragraph: yellow liquid used in the production of synthetic rubber. Its condensed structural formula is ClSSCl. Ethylene glycol is the major ingredient in antifreeze. Its condensed structural formula is HOCH2CH2OH. Trimethylamine is one of the substances responsible for the smell of spoiled fish. Its condensed structural formula is (CH3)3N. Given: condensed structural formula Asked for: molecular formula Strategy: A Identify every element in the condensed structural formula and then determine whether the compound is organic or inorganic. B As appropriate, use either organic or inorganic convention to list the elements. Then add appropriate subscripts to indicate the number of atoms of each element present in the molecular formula. Solution: The molecular formula lists the elements in the molecule and the number of atoms of each. Q: Trimethylamine is one of the substances responsible for the what of spoiled fish? Choices: - appearance - decay - feel - smell A:
(A).
smell

Ques: Answer the following question given this paragraph: Insight learning , which is based on past experience and reasoning, is a hallmark of the human animal. Humans have used insight learning to solve problems ranging from starting a fire to traveling to the moon. It usually involves coming up with new ways to solve problems. Insight learning generally happens quickly. An animal has a sudden flash of insight. Insight learning requires relatively great intelligence. Human beings use insight learning more than any other species. They have used their intelligence to solve problems ranging from inventing the wheel to flying rockets into space. Q: What type of learning is based on past experience and reasoning? Choices: - experiment - theory - reflect - insight A:
Ans:
insight
