This answer to this question is Paramecia, cilia
The assumption in this problem is that the gas, CO2, is ideal and that the ideal gas law is applicable such that,
n = PV/RT
We simply substitute the given values to the equation above,
n = (1 atm)(V) / (0.082 Latm/mol.K)(T)
n = 12.20 V/T
Answer:
Feathers initially evolved in a role associated with sexual selection.
Explanation:
In species where only males had feathers, these feathers can be considered to have evolved into a role associated with sexual selection. This is because in these species, males used their feathers as a sexual attraction for females, in this case, females chose the males that had more attractive feathers to mate and generate new individuals for the species. An example of this can be seen in the peacock, where the tail with lush feathers is only present in males and is intended to sexually attract females.
