Answer: D. Species
Explanation:
Species is a group of population in which organisms have many common characteristics and they are capable of interbreeding and producing viable fertile offsprings. The members belonging to the same class and phylum have less common characteristics if they interbreed they may not produce viable fertile offsprings. Also, the organisms of the same kingdom have least common characteristics and will not have viable fertile offsprings after interbreeding.
The answer would be D, as even though both velocity and speed may share similar resultants in this scenario, speed is a scalar, while velocity is a vector. Thus, velocity can have direction and move negatively (the opposite direction from which it started) while speed is a measurement of quantity.
They can also use carbohydrates so I don't know
Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system is the part of the autonomic system of neurons which gets activated in the condition of stress.
The stress conditions activate the sympathetic nervous system which prepares the human body for the stress condition by either fight or flight mode.
The fight or flight responses requires a large amount of energy which are produced by the activation of the parasympathetic energy therefore the sympathetic system involves the expenditure of the energy. The system is also involved in sexual arousal.
Thus, the Sympathetic nervous system is the correct answer.
