Answer:
The simplest mechanism by which molecules can cross the plasma membrane is passive diffusion. Passive diffusion is thus a nonselective process by which any molecule able to dissolve in the phospholipid bilayer is able to cross the plasma membrane and equilibrate between the inside and outside of the cell.
Answer:
Even though they are the same temperature, the metal will feel colder than the wood because of the thermal conductivity of the metal, compared to the wood. Metal is a good conductor of heat, hence it sends away the heat. On the other hand, wood is a poor conductor of heat, hence releases the heat too slowly.
Answer:
b. Talus, tibia and fibula
Explanation:
In this scenario, the diagnosis was that the extreme eversion and plantar flexion that occurred during the fall resulted in a severe dislocation of the ankle joint proper (talocrural joint) and spraining of the ankle at the calcaneofibular ligament. The surgeon stated that she would perform a reduction of the dislocation and then attempt to repair the injured ligament using arthroscopy. Thus, the bones which would have been dislocated are talus, tibia and fibula.
Generally, when the anterior cruciate ligament which is one of the key ligaments that stabilizes the knee joint is damaged, a surgeon would have to perform a reconstruction. The tibia bone is a shinbone and it is connected by the anterior cruciate ligament with the femur (thighbone).
Basically, the ankle joint is made up of three (3) main bones and these are the tibia, talus and fibula, thus, they would all need to be repaired by the surgeon through arthroscopy.
The right answer is compression.
There are basically two types of constraints that deform rocks: compression and tension constraints. In compression, forces converge; they can be coaxial or not.
The deformation of a card set under compression constraints illustrates the difference: In the case of a coaxial compression constraint, the cards will be arched. If the stresses are not coaxial, shear will develop; the card game is deformed by sliding the cards on top of each other:
