Answer:
D.) nitrogen fixation
Explanation:
Nitrogen is in the soil and helps plants grow. This process is nitrogen fixation.
Answer:
D - Removes toxins and waste from the blood stream
The answer is A Bescause is that
<span>The correct answer is:
</span>When using a real machine to do work, input work will always be <span><u>greater than output work, because energy is lost to the environment by the machine.
</u></span><span>
Energy is lost by the machine in the environment through the process of heat and friction. This is one of the many obvious laws of physics that output work always entails the loss of energy in the form of heat one way or another.

Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
