Answer the following question given this paragraph: Pluto has three moons of its own. The largest, Charon, is big compared to Pluto. The Pluto-Charon system is sometimes called a double dwarf planet ( Figure above ). Two smaller moons, Nix and Hydra, were discovered in 2005. Q: How many moons does pluto have? A:
****
A: three

Answer the following question given this paragraph: Figure 9.3 Intervertebral Disc An intervertebral disc unites the bodies of adjacent vertebrae within the vertebral column. Each disc allows for limited movement between the vertebrae and thus functionally forms an amphiarthrosis type of joint. Intervertebral discs are made of fibrocartilage and thereby structurally form a symphysis type of cartilaginous joint. Q: What are intervertebral discs made of? A:
OPTIONS:
- intercartilage
- fibrotissue
- connective cartilage
- fibrocartilage
fibrocartilage

Answer the following question given this paragraph: Earth is a round, three-dimensional ball. In a small area, Earth looks flat, so it is not hard to make accurate maps of a small place. When mapmakers want to map the round Earth on flat paper, they use projections. What happens if you try to flatten out the skin of a peeled orange? Or if you try to gift wrap a soccer ball? To flatten out, the orange peel must rip, and its shape must become distorted. To wrap a round object with flat paper requires lots of extra cuts and folds. A projection is a way to represent Earth's curved surface on flat paper ( Figure below ). Q: What method is used to map the earth on flat paper? A:
OPTIONS:
- calculations
- forecasts
- surveying
- projections

Answer: projections

input with options: Answer the following question given this paragraph: As the membrane depolarizes, another set of ion channels called voltage-gated sodium channels are triggered to open. Sodium ions enter the muscle fiber, and an action potential rapidly spreads (or "fires") along the entire membrane to initiate excitation-contraction coupling. Things happen very quickly in the world of excitable membranes (just think about how quickly you can snap your fingers as soon as you decide to do it). Immediately following depolarization of the membrane, it repolarizes, re-establishing the negative membrane potential. Meanwhile, the ACh in the synaptic cleft is degraded by the enzyme acetylcholinesterase (AChE) so that the ACh cannot rebind to a receptor and reopen its channel, which would cause unwanted extended muscle excitation and contraction. Propagation of an action potential along the sarcolemma is the excitation portion of excitation-contraction coupling. Recall that this excitation actually triggers the release of calcium ions (Ca++) from its storage in the cell's SR. For the action potential to reach the membrane of the SR, there are periodic invaginations in the sarcolemma, called T-tubules ("T" stands for "transverse"). You will recall that the diameter of a muscle fiber can be up to 100 m, so these T-tubules ensure that the membrane can get close to the SR in the sarcoplasm. The arrangement of a T-tubule with the membranes of SR on either side is called a triad (Figure 10.7). The triad surrounds the cylindrical structure called a myofibril, which contains actin and myosin. Q: What is the arrangement of a t-tubule with the membranes of sr on either side called? A:
OPTIONS:
- aracnid
- orchid
- acid
- triad
output:
triad
