Air is primarily composed of nitrogen and oxygen gases. which state of these gases can conduct electricity?

Plasma state

Explanation:

Nitrogen and oxygen in their gaseous stage are considered as insulator as they are not able to pass electricity through them. Electricity can be conducted through a medium when electrons move.

Hence, when both nitrogen and oxygen are in plasma state they conduct electricity. A plasma state of a gas is the state in which it exists in ionized state where electrons are able to move freely.

hence , Plasma state is correct.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

i would think it's dendrites
