The statement "The insect vectors have six legs and include ticks, mosquitoes, and lice" is True.
Vectors are living organisms which can transfer infectious pathogens among humans and also from animals to humans.
Insect vectors include the bloodsucking insects, which take-in the disease-causing microorganisms (pathogens) during a blood meal from an infected host (human or animal) and transfer it to a new host afterwards.
Oftentimes, when a vector turns infectious, it is competent enough to transmit the pathogen for the rest of its life during every successive bite or blood meal.
Mosquitoes are vectors of Malaria, tick-borne encephalitis is transmitted by ticks whereas Typhus is transmitted by lice.

It is accepted to be fact by those who accept it to be fact, until further experimentation or research can prove otherwise
The given statement is True.
<u>Explanation:</u>
The Charles Darwin developed the theory called Darwinism theory of evolution. The theory states that all the species of the organisms arises and developed through the small, inherited variations in the organisms that increase the individual ability to complete the survive and reproduce.
The individual species are not having identical traits that are passed from the generation to generation. The offspring are born that can survive, only the survive of the completion for resources will reproduce; he describes how the species can change in shape and character through the selective breeding.
Answer:
Cuticle
Explanation:
Plant cuticle is a waxy covering over the aerial epidermal cells of all the plants. Waxes are composed of cutin and a various organic solvent-soluble lipids. The cuticle is an extracellular hydrophobic layer which provides protection against desiccation and external environmental stresses. In other words the cucticle helps to retain water and give plants an adavanthe to live terrestrial life.
