Answer the following question given this paragraph: Facilitated diffusion is the diffusion of solutes through integral membrane transport proteins. Facilitated diffusion is a type of passive transport . Even though facilitated diffusion involves transport proteins (and is essentially a transport process), it can still be considered passive transport because the solute is moving down the concentration gradient, and no input of energy is required. Facilitated diffusion utilizes proteins known as uniporters. A uniporter can be either a channel protein or a carrier protein. Q: Because the solute is moving down the concentration gradient, and no input of energy is required, facilitated diffusion is considered what type of transport? Choices: - active - neutral - adaptive - passive A:
passive
Answer the following question given this paragraph: In many parts of the world, table salt is obtained from the evaporation of sea water. The heat for the process comes from the sun. Q: What results from the evaporation of sea water? Choices: - carbon-di-oxide - reef - oxygen - salt A:
salt
Q: Answer the following question given this paragraph: Figure 7.22 Osteoporosis Osteoporosis is an age-related disorder that causes the gradual loss of bone density and strength. When the thoracic vertebrae are affected, there can be a gradual collapse of the vertebrae. This results in kyphosis, an excessive curvature of the thoracic region. Q: What is the age-related disorder that causes the gradual loss of bone density and strength? Choices: - mitosis - arthritis - fibrosis - osteoporosis A:
A: osteoporosis
Question: Answer the following question given this paragraph: (a) Two solutions of differing concentrations are placed on either side of a semipermeable membrane. (b) When osmosis occurs, solvent molecules selectively pass through the membrane from the dilute solution to the concentrated solution, diluting it until the two concentrations are the same. The pressure exerted by the different height of the solution on the right is called the osmotic pressure. The osmotic pressure of a solution is easy to calculate:. Q: When solvent molecules selectively pass through a membrane from a dilute solution to concentrated solution, what process is occurring? Choices: - plasmolysis - active transport - diffusion - osmosis A:
Answer: osmosis

Answer the following question given this paragraph: Properties of matter fall into one of two categories. If the property depends on the amount of matter present, it is an extensive property. The mass and volume of a substance are examples of extensive properties; for instance, a gallon of milk has a larger mass and volume than a cup of milk. The value of an extensive property is directly proportional to the amount of matter in question. If the property of a sample of matter does not depend on the amount of matter present, it is an intensive property. Temperature is an example of an intensive property. If the gallon and cup of milk are each at 20 C (room temperature), when they are combined, the temperature remains at 20 C. As another example, consider the distinct but related properties of heat and temperature. A drop of hot cooking oil spattered on your arm causes brief, minor discomfort, whereas a pot of hot oil yields severe burns. Both the drop and the pot of oil are at the same temperature (an intensive property), but the pot clearly contains much more heat (extensive property). Q: Extensive and intensive are categories of properties that apply to what? Choices: - volume - weight - height - matter A:
**Answer**
matter

Answer the following question given this paragraph: 43.5 | Human Pregnancy and Birth By the end of this section, you will be able to: Explain fetal development during the three trimesters of gestation Describe labor and delivery Compare the efficacy and duration of various types of contraception Discuss causes of infertility and the therapeutic options available Pregnancy begins with the fertilization of an egg and continues through to the birth of the individual. The length of time of gestation varies among animals, but is very similar among the great apes: human gestation is 266 days, while chimpanzee gestation is 237 days, a gorilla's is 257 days, and orangutan gestation is 260 days long. The fox has a 57-day gestation. Dogs and cats have similar gestations averaging 60 days. The longest gestation for a land mammal is an African elephant at 640 days. The longest gestations among marine mammals are the beluga and sperm whales at 460 days. Q: What land mammal has the longest gestation period? Choices: - Rhino - Giraffe - Asian elephant - african elephant A:
(Answer)
african elephant
