Q: Phase labels - and even special conditions - are sometimes included for the substances that are part of what? Read this paragraph and choose the correct option from the provided answers: Many chemical equations also include phase labels for the substances: (s) for solid, () for liquid, (g) for gas, and (aq) for aqueous (i. , dissolved in water). Special conditions, such as temperature, may also be listed above the arrow. For example, 2NaHCO. Choices: - solid equations - toxic equations - carbon equations - chemical equations A:

Q: A molecule has two structures that can be generated. what is this called? Read this paragraph and choose the correct option from the provided answers: The cis isomer has the two single hydrogen atoms on the same side of the molecule, while the trans isomer has them on opposite sides of the molecule. In both molecules, the bonding order of the atoms is the same. In order for geometric isomers to exist, there must be a rigid structure in the molecule to prevent free rotation around a bond. If the double bond in an alkene was capable of rotating, the two geometric isomers above would not exist. In addition, the two carbon atoms must each have two different groups attached in order for there to be geometric isomers. Propene has no geometric isomers because one of the carbon atoms has two single hydrogens bonded to it. Choices: - resonance hybrids - congruence - ethnocentrism - isomerism A:
(Answer)
isomerism

Ques: Q: If the frequency of the electromagnetic wave is the same as the natural frequencies of the system, the transfer of what is much more efficient? Read this paragraph and choose the correct option from the provided answers: 24.4 Energy in Electromagnetic Waves Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes this energy is obvious, such as in the warmth of the summer sun. Other times it is subtle, such as the unfelt energy of gamma rays, which can destroy living cells. Electromagnetic waves can bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. If the frequency of the electromagnetic wave is the same as the natural frequencies of the system (such as microwaves at the resonant frequency of water molecules), the transfer of energy is much more efficient. Connections: Waves and Particles The behavior of electromagnetic radiation clearly exhibits wave characteristics. But we shall find in later modules that at high frequencies, electromagnetic radiation also exhibits particle characteristics. These particle characteristics will be used to explain more of the properties of the electromagnetic spectrum and to introduce the formal study of modern physics. Another startling discovery of modern physics is that particles, such as electrons and protons, exhibit wave characteristics. This simultaneous sharing of wave and particle properties for all submicroscopic entities is one of the great symmetries in nature. Choices: - heat - sound - light - energy A:
Ans: energy

Q: When food is scarce, starving cells secrete a molecule that stimulates neighboring cells to do what? Read this paragraph and choose the correct option from the provided answers: Choices: - compete - hoard energy - die off - aggregate A:
(A).
aggregate

Ques:Q: What are two nonliving things that all living things need for survival? Read this paragraph and choose the correct option from the provided answers: Choices: - sunlight - calcium - methane - water and air A:

Ans:water and air

Ques: Q: Broca's area, responsible for the production of language or controlling movements responsible for speech, is nearly always located on what side of the brain? Read this paragraph and choose the correct option from the provided answers: are responsible for establishing long-term memory, but the ultimate location of those memories is usually in the region in which the sensory perception was processed. The main sensation associated with the parietal lobe is somatosensation, meaning the general sensations associated with the body. Posterior to the central sulcus is the postcentral gyrus, the primary somatosensory cortex, which is identified as Brodmann's areas 1, 2, and 3. All of the tactile senses are processed in this area, including touch, pressure, tickle, pain, itch, and vibration, as well as more general senses of the body such as proprioception and kinesthesia, which are the senses of body position and movement, respectively. Anterior to the central sulcus is the frontal lobe, which is primarily associated with motor functions. The precentral gyrus is the primary motor cortex. Cells from this region of the cerebral cortex are the upper motor neurons that instruct cells in the spinal cord to move skeletal muscles. Anterior to this region are a few areas that are associated with planned movements. The premotor area is responsible for thinking of a movement to be made. The frontal eye fields are important in eliciting eye movements and in attending to visual stimuli. Broca's area is responsible for the production of language, or controlling movements responsible for speech; in the vast majority of people, it is located only on the left side. Anterior to these regions is the prefrontal lobe, which serves cognitive functions that can be the basis of personality, short-term memory, and consciousness. The prefrontal lobotomy is an outdated mode of treatment for personality disorders (psychiatric conditions) that profoundly affected the personality of the patient.

Ans:
