Answer:
Compare and Contrast the relationships between the speed of electromagnetic and mechanical waves as they travel through different mediums is explained below in details.
Explanation:
As per the mechanism, the waves can be distinguished as electromagnetic and mechanical waves. Electromagnetic waves are those fluctuations that have no mechanism to progress whereas mechanical waves demand a mechanism for their communication. Electromagnetic waves progress in a vacuum whereas mechanical waves don't have.

Answer:
an individual having two different alleles for a specific trait.
Explanation:
B) It is a fluid mosaic model, with proteins interspaced in the phospholipids, both of which can freely move laterally.
Explanation:
The fluid mosaic model proposed by Singer and Nicolson describes the plasma membrane’s structure as a mosaic pattern of components consisting of phospholipids, proteins, cholesterol, and carbohydrates; all of which provides the unique fluid character of the membrane.
According to this model, the phospholipids constitute the main fabric, cholesterol attaches between the phospholipids in between the layers, integral proteins embedded within the bilayers of the phospholipids, peripheral proteins along the peripheries of the layers and carbohydrates outside the membranous layers.
