Semipermeable cell membranes are made of phospholipids that form a bilayer. What major benefit does this arrangement of the memb
Andrej [43]

Answer:

The correct answer would be c. The cell has a greater level of structural support.

Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.

They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.

  • Lipid bilayer gives the rigidity or shape to the cell.  
  • It isolates the cell from the sorroundings.
  • It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
  • Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.

Hence, most appropriate choice would be c. The cell has a greater level of structural support.

An animal trainer is conditioning an elephant to startle at the sound of a trombone. Every time she plays the trombone, she then
ANTONII [103]

Answer:

The correct answer is option D, that is, the elephant will not react.

Explanation:

A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.  

In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.
