Answer:
Red Blood Cell lacks a nucleus, it would be unable to carry oxygen efficiently.
Explanation:
The absence of a nucleus is an adaptation of the red blood cell for its role. This allows the red blood cell to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its own distinctive bivalve shape, which promotes diffusion.

The correct answer is option D
The population of rabbit over the first unit of time is reduced because the population of snakes was more than the normal population.
The predators of rabbits are snakes and if the population of predator will be more than the population of the rabbit then snakes will eat them. Ultimately the population of rabbit will be decreased.
Then after some time the population of rabbit increased as the population of snakes decreased.
Answer:
b. a fluid-mosaic of phospholipids and proteins
Explanation:
According to the currently accepted structure, the cell membrane is made up of two layers of amphipathic phospholipids in which proteins are embedded or present. The hydrophobic tails of phospholipids make the core of the membrane. These tails are not covalently attached to each other and are free to move laterally. Likewise, the protein molecules float in the fluid bilayer. This mosaic pattern is not static since the positions of the proteins in the bilayer are constantly changing. The fluid mosaic model to explain the structure of the cell membrane was given by S.J. Singer and Garth L. Nicolson in 1972.
