input: OPTIONS:
- classic permeation
- induced permeation
- radiation permeation
- selective permeation Now, answer this question: Answer the following question given this paragraph: Osmosis and Osmotic Pressure of Solutions A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally referred to as semipermeable membranes. Consider the apparatus illustrated in Figure 11.25, in which samples of pure solvent and a solution are separated by a membrane that only solvent molecules may permeate. Solvent molecules will diffuse across the membrane in both directions. Since the concentration of solvent is greater in the pure solvent than the solution, these molecules will diffuse from the solvent side of the membrane to the solution side at a faster rate than they will in the reverse direction. The result is a net transfer of solvent molecules from the pure solvent to the solution. Diffusion-driven transfer of solvent molecules through a semipermeable membrane is a process known as osmosis. Q: What term means that only molecules or ions of a certain size, shape, polarity or charge are capable of passing through the material? A:
A:
output: selective permeation

Answer the following question given this paragraph: Q: What part of the plant anchors it into the soil? A:

OPTIONS:
- stems
- buds
- leaves
- roots

Answer: roots

Problem: OPTIONS:
- Position Replacement
- acceleration
- Direction Replacement
- velocity
Q: Answer the following question given this paragraph: Velocity is defined as change in position over time. Can you see that would be the slope of this graph? (slope = rise over run and in this case the 'rise' is position and the 'run' is time). Find the instantaneous speed at sec. Q: What term refers to change in position over time? A:
Answer: velocity

Problem:OPTIONS:
- asexual and biological
- atypical and sexual
- ideal and sexual
- asexual and sexual

Answer the following question given this paragraph: Most protists also have a complex life cycle. The life cycle of an organism is the cycle of phases it goes through until it returns to the starting phase. The protist life cycle includes both sexual and asexual reproduction. Why reproduce both ways? Each way has benefits. Asexual reproduction is fast. It allows rapid population growth when conditions are stable. Sexual reproduction increases genetic variation. This helps ensure that some organisms will survive if conditions change. Q: The protist life cycle benefits by including what forms of reproduction? A:
****
A: asexual and sexual

Answer the following question given this paragraph: Cartilaginous Joints Cartilaginous joints are joints in which the bones are connected by cartilage. There are two types of cartilaginous joints: synchondroses and symphyses. In a synchondrosis, the bones are joined by hyaline cartilage. Synchondroses are found in the epiphyseal plates of growing bones in children. In symphyses, hyaline cartilage covers the end of the bone but the connection between bones occurs through fibrocartilage. Symphyses are found at the joints between vertebrae. Either type of cartilaginous joint allows for very little movement. Synovial Joints Synovial joints are the only joints that have a space between the adjoining bones (Figure 38.25). This space is referred to as the synovial (or joint) cavity and is filled with synovial fluid. Synovial fluid lubricates the joint, reducing friction between the bones and allowing for greater movement. The ends of the bones are covered with articular cartilage, a hyaline cartilage,. Q: What term is used to describe joints in which the bones are connected by cartilage? A:
OPTIONS:
- capillaries joints
- blob joints
- spinal joins
- cartilaginous joints
cartilaginous joints

Answer the following question given this paragraph: Bacterial contamination of foods can lead to digestive problems, an illness known as food poisoning . Raw eggs and undercooked meats commonly carry the bacteria that can cause food poisoning. Food poisoning can be prevented by cooking meat thoroughly, which kills most microbes, and washing surfaces that have been in contact with raw meat. Washing your hands before and after handling food also helps prevent contamination. Q: Bacterial contamination of foods can lead to digestive problems, an illness known as what? A:
OPTIONS:
- acid reflux
- headache
- ulcers
- food poisoning

Answer:
food poisoning
