Answer:
The influenza H1N1 virus is transmitted through saliva droplets and mucus from sick people, who by sneezing or coughing without covering their mouth and nose adequately, leave the virus in the air or on their hands, infecting then the objects they touch. As a rare occurrence, a person can become infected with the flu by touching a surface or object contaminated with the influenza virus and then touching the mouth, nose, or eyes.
Pigs sometimes transmit influenza H1N1 virus to people, primarily pig farmers and veterinarians.

Answer:
Option C - The sympatric salamander populations evolved their present body sizes after they became sympatric.
Explanation:
First, note the definitions of each terms.
1) Sympatric occurs when organisms especially of same species occurring in the same, or in overlapping territory, do not interbreed.
2) Allopatric occurs when organisms are NOT living in the same territory and thus unable to crossbreed.
On 1st QUESTION
The argument would be strengthened by the failure of P. cinereus and P. hoffmani to crossbreed making traits for body size to become distinct (dissimilar) in each specie.
On 2nd QUESTION
Definitely, salamanders species occurring in the territory, do not interbreed after they became sympatric, thus, making characters among same species to be increasingly different over generations.
The correct answer is gamete.
