Q: Between meals, when the level of blood glucose drops below a certain point, a signal is sent to what organ saying "make more glucose"? Read this paragraph and choose the correct option from the provided answers: Shortly after eating, there is a surplus of glucose in the body. Some of it will be used immediately, but the rest is stored in the form of glycogen. Between meals, when the level of glucose in the blood drops below a certain point, a signal is sent to the liver that says "make more glucose. " In response, the glycogen in the liver is broken down and the resulting glucose is released into the bloodstream. Choices: - pancreas - kidney - brain - liver A:
liver

Q: What hormone controls milk production in mammary glands? Read this paragraph and choose the correct option from the provided answers: Choices: - melanin - pepsin - dopamine - prolactin A:
prolactin

Q: Dna transcription is controlled by what type of proteins? Read this paragraph and choose the correct option from the provided answers: As shown in Figure below , transcription is controlled by regulatory proteins . The proteins bind to regions of DNA, called regulatory elements , which are located near promoters. After regulatory proteins bind to regulatory elements, they can interact with RNA polymerase, the enzyme that transcribes DNA to mRNA. Regulatory proteins are typically either activators or repressors. Choices: - essential - digested - genetic - regulatory A:
regulatory

Q: What force increases a slide downhill and decreases a slide uphill? Read this paragraph and choose the correct option from the provided answers: Discussion As might have been expected, the player slides a shorter distance by sliding uphill. Note that the problem could also have been solved in terms of the forces directly and the work energy theorem, instead of using the potential energy. This method would have required combining the normal force and force of gravity vectors, which no longer cancel each other because they point in different directions, and friction, to find the net force. You could then use the net force and the net work to find the distance d that reduces the kinetic energy to zero. By applying conservation of energy and using the potential energy instead, we need only consider the gravitational potential energy. Choices: - nuclear - frictional - tension - gravity A:
gravity
