Q: When atomic orbitals hybridize, the valence electrons occupy these? Read this paragraph and choose the correct option from the provided answers: When atomic orbitals hybridize, the valence electrons occupy the newly created orbitals. The Be atom had two valence electrons, so each of the sp orbitals gets one of these electrons. Each of these electrons pairs up with the unpaired electron on a chlorine atom when a hybrid orbital and a chlorine orbital overlap during the formation of the BeCl bonds. Choices: - newly created elements - newly developed orbits - expanded pathways - newly created orbitals A:
newly created orbitals

Q: Skeletal muscle cells and cardiac muscle cells share what property, which is not shared by smooth muscle cells? Read this paragraph and choose the correct option from the provided answers: Figure 33.18 Smooth muscle cells do not have striations, while skeletal muscle cells do. Cardiac muscle cells have striations, but, unlike the multinucleate skeletal cells, they have only one nucleus. Cardiac muscle tissue also has intercalated discs, specialized regions running along the plasma membrane that join adjacent cardiac muscle cells and assist in passing an electrical impulse from cell to cell. Choices: - surfaces - overlap - filaments - striations A:
striations

Q: Q: What are resources that can not be remade, or would take too long to remake to keep up wiht human use called? Read this paragraph and choose the correct option from the provided answers: Nonrenewable resources are natural resources that can't be remade or else take too long to remake to keep up with human use. Examples of nonrenewable resources are coal, oil, and natural gas, all of which are fossil fuels. Fossil fuels form from the remains of plants and animals over hundreds of millions of years. We are using them up far faster than they can be replaced. At current rates of use, oil and natural gas will be used up in just a few decades, and coal will be used up in a couple of centuries. Choices: - renewable resources - green resources - photoreactive resources - nonrewable resources A:
A: nonrewable resources

Question: Q: Terrestrial animals lose water by evaporation from their skin and which surfaces? Read this paragraph and choose the correct option from the provided answers: Choices: - anaerobic - digestive - pulmonary - respiratory A:
Answer: respiratory
