- Which option is not true?
Functional MRI can be used to image
Ultrasound imaging uses radio waves to capture an image
PET relies on positrons and electrons
CT scanning produces multiple images of the inside of the body
- What is not true regarding material properties?
A viscoelastic material exhibits viscous and elastic characteristics
Elasticity is the capacity of a strained material to recover after a deformation
A viscous material does not resist shear flow thus strain linearly when a stress is applied
When a material is permanently deformed it stops being elastic
- What is true regarding cancer?
Cancer cells continue with normal cell communication but don’t specialize
Cancers at an invasive stage can dampen growth of blood vessels
Newest method to treat cancer is surgery
Radiation and chemotherapy are methods that are used to kill cancer cells

- Acetylcholine (ACh) is the primary neurotransmitter responsible for muscle contraction. The binding of ACh to receptors on muscle cells activates a signal transduction pathway that causes the muscle to contract. Acetylcholinesterase, the digestive enzyme found on the membranes of muscle cells, is responsible for the breakdown of ACh over time, ending the activation of muscular contraction. Certain chemical compounds, such as sarin gas, act as high-affinity inhibitors of acetylcholinesterase. Which of the following describes the most likely effect that exposure to sarin would have on muscle cells? A B с D complete inhibition of muscle contraction slower transduction of the muscle contraction pathway decrease in the frequency of muscle contraction convulsions due to continuous muscle contractionarrow_forwardSuppose a certain liquid in contact with a surface has cohesive and adhesive forces such that its behavior is exactly between wetting and not wetting a surface.

- send a small electrical current through the One way to characterise biological tissue is tissue and measure the opposition to flow of that current through the tissue. In humans, the resistivity of fat is considerably greater than for muscle, which in turn is considerably greater than for blood and other body fluids. This can be used to analyse body composition, in particular, to estimate body fat percentage. (a) Using a simple model of fat versus non-fat tissue, draw a circuit diagram to represent the possible flows of current through the tissue (b) Why would the analysis of body composition need to take into account the height and weight of the person? (c) How could the level of hydration or electrolyte abnormalities in the person affect the results of the analysis?

Increasing the rate of heating of a substance at its melting point only causes more rapid melting. When the melting point is reached, ther thermal energy is sufficient to overcome intermolecular forces holding the components at their statioinary points. Thermal energy causes the components of the solid to vibrate faster. Heating of the now formed liquid results in increaseing the liquid temperture.arrow_forward
