Q: Answer the following question given this paragraph: Carbon (atomic number 6) has six electrons. Four of them fill the 1s and 2s orbitals. The remaining two electrons occupy the 2p subshell. We now have a choice of filling one of the 2p orbitals and pairing the electrons or of leaving the electrons unpaired in two different, but degenerate, p orbitals. The orbitals are filled as described by Hund's rule: the lowest-energy configuration for an atom with electrons within a set of degenerate orbitals is that having the maximum number of unpaired electrons. Thus, the two electrons in the carbon 2p orbitals have identical n, l, and ms quantum numbers and differ in their ml quantum number (in accord with the Pauli exclusion principle). The electron configuration and orbital diagram for carbon are:. Q: Subshells are subdivisions of what groupings of electrons that can be found surrounding atoms? A:
Answer: orbitals

Problem:OPTIONS:
- parallel
- groups
- lines
- series

Answer the following question given this paragraph: Resistors in Series: All resistors are connected end to end. There is only one river, so they all receive the same current. But since there is a voltage drop across each resistor, they may all have different voltages across them the sum of the voltage drops will equal the total voltage of the circuit. The more resistors in series the more rocks in the river, so the less current that flows. Q: Resistors connected end to end are said to be in what? A:
****
A: series

Answer the following question given this paragraph: 36.2 | Somatosensation By the end of this section, you will be able to: Describe four important mechanoreceptors in human skin Describe the topographical distribution of somatosensory receptors between glabrous and hairy skin Explain why the perception of pain is subjective Somatosensation is a mixed sensory category and includes all sensation received from the skin and mucous membranes, as well from as the limbs and joints. Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch. Somatosensation occurs all over the exterior of the body and at some interior locations as well. A variety of receptor typesembedded in the skin, mucous membranes, muscles, joints, internal organs, and cardiovascular systemplay a role. Recall that the epidermis is the outermost layer of skin in mammals. It is relatively thin, is composed of keratin-filled cells, and has no blood supply. The epidermis serves as a barrier to water and to invasion by pathogens. Below this, the much thicker dermis contains blood vessels, sweat glands, hair follicles, lymph vessels, and lipid-secreting sebaceous glands (Figure 36.4). Below the epidermis and dermis is the subcutaneous tissue, or hypodermis, the fatty layer that contains blood vessels, connective tissue, and the axons of sensory neurons. The hypodermis, which holds about 50 percent of the body's fat, attaches the dermis to the bone and muscle, and supplies nerves and blood vessels to the dermis. Q: Somatosensation refers to what of the five senses? A:
OPTIONS:
- balance
- thought
- sight
- touch
touch

Answer the following question given this paragraph: Some substances in food cannot be broken down into nutrients. They remain behind in the digestive system after the nutrients are absorbed. Any substances in food that cannot be digested and absorbed pass out of the body as solid waste. The process of passing solid food waste out of the body is called elimination. Q: What is the name of the process in which solid food waste is passed out of the body? A:
OPTIONS:
- extinction
- evaporation
- regurgitation
- elimination

Answer:
elimination
