It is metallic, has cleavage, and can be scratched with special equipment.
Explanation:
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.
Answer: The answer would be "plant-like protists". These protists make their energy on sunlight. This would make them a protist and a plant-like cell.
i think this is the answer. if not plz feel free to tell me
Answer:
An organism is able to produce sweat so that it cools off which helps it to cool down when exposed to high temperatures.
It's vessels are able to vasodilate and vasoconstrict to regulate temperature.
An organism stores fat as an insulator.
Eye pupils dilate and constrict to control the amount of light entering the eye.
If an organism touches a hot surface, nerve impulses are sent to the body to move and not get injured.
In a nutshell: an organism maintain a constant internal environment with homeostasis. And is able to respond to changes in the atmosphere by electrical impulses (nervous system) or the endocrine system by the release of chemicals (called hormones)
