Q: What is the name of the procedure where an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it? Read this paragraph and choose the correct option from the provided answers: In a procedure called elemental analysis , an unknown compound can be analyzed in the laboratory in order to determine the percentages of each element contained within it. These percentages can be transformed into the mole ratio of the elements, which leads to the empirical formula. The steps to be taken are outlined below. Choices: - electrical analysis - chemical analysis - gaseous analysis - elemental analysis A:
elemental analysis

Q: What is necessary for new alleles to be created? Read this paragraph and choose the correct option from the provided answers: No new mutations are occurring. Therefore, no new alleles are being created. Choices: - cross-pollination - new rna - new frequencies - new mutations A:
new mutations

Q: Q: Microevolution occurs in a population when what frequencies change over time? Read this paragraph and choose the correct option from the provided answers: Microevolution occurs in a population when its allele frequencies change over time. There are four major forces of evolution that cause allele frequencies to change: mutation, gene flow, genetic drift, and natural selection. Choices: - eukaryote - molecule - antenna - allele A:
A: allele

Question: Q: What is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern? Read this paragraph and choose the correct option from the provided answers: Diamond is a network solid and consists of carbon atoms covalently bonded to one another in a repeating three-dimensional pattern. Each carbon atom makes four single covalent bonds in a tetrahedral geometry. Choices: - a zirconium - a ruby - an agate - a diamond A:
Answer: a diamond

Q: What is the term for the temperature at which a solid changes into a liquid? Read this paragraph and choose the correct option from the provided answers: The melting point is the temperature at which a solid changes into a liquid. Choices: - the starting point - the mixture point - the pressure point - the melting point A:
**Answer**
the melting point

Q: Q: What is the lowest energy state of the atom called? Read this paragraph and choose the correct option from the provided answers: The electrons in an atom tend to be arranged in such a way that the energy of the atom is as low as possible. The ground state of an atom is the lowest energy state of the atom. When those atoms are given energy, the electrons absorb the energy and move to a higher energy level. These energy levels of the electrons in atoms are quantized, meaning again that the electron must move from one energy level to another in discrete steps rather than continuously. An excited state of an atom is a state where its potential energy is higher than the ground state. An atom in the excited state is not stable. When it returns back to the ground state, it releases the energy that it had previously gained in the form of electromagnetic radiation. Choices: - work state - active state - base state - ground state A:
A: ground state
