Answer: Option B
Explanation: The thin layer that forms the outer covering of the cell is known as the cell membrane. It is composed of the lipid bilayer which as embedded proteins.
This membrane is selectively permeable which means it allows only specific molecules to pass through them.
The main function of cell membrane is to protect the cell from the outer environment and by the invasion of harmful bacteria and viruses.
The tick is considered the vector in the chain of infection.
Generally, vector organisms are organisms that are capable of transmitting disease pathogens from infected organisms to uninfected ones either directly or indirectly as a result of their activities.
Ticks are parasites that feed on the blood of vertebrate animals such as deers and humans. When they feed on the blood of animals with certain infections, the pathogens for such infections are sometimes carried in the guts of the parasites and these are transferred to the bloodstream of the next animal that would be their host.
A good example of this is Lyme disease.

A result of convergent evolution are the webbed feet of ducks and frogs.
Explanation:
The evolution of the animals, or rather the development of adaptive features, works in very interesting manner. It is very common in nature that animals that are closely related do not share similar characteristics, or the opposite, animals that are not closely related but share similar characteristics. The later case, is referred to as convergent evolution, where totally different animals have developed the same or very similar characteristics in order to be better suited for their environment.
In this case we have the ducks and frogs, and the webbed feet as shared adaptations, or feature. The ducks are birds, while the frogs are amphibians, and their last common ancestor has lived hundreds of millions of years ago. Despite that, both animals have developed webbed feet, and the reason for this has been that both animals have faced the same challenge, swimming and diving, and the webbed feet help them to be much faster and more agile in the water.
Other examples of convergent evolution (in the present and in the past) are:
- Hyena - Tasmanian devil
- Sandy cat - Fenec fox
- Smilodon - Thylacosmilus
- Bats - Birds
