Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for
vladimir1956 [14]

Answer:

1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. <u>Action potential. </u>

2. neurons that detect chemicals such as those found in food. <u>Chemoreceptors. </u>

3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. <u>Compound eyes. </u>

4. the structure that gives the response to an environmental change.<u> Effector</u>

5. neurons that detect electrical fields. <u>Electroreceptors. </u>

6. secretion of hormones into the blood stream to affect distant processes. <u>Endocrine.</u>

Explanation:  

An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.

There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.

Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.

The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.

There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

You are watching sleep researchers monitor the sleep of a normal adult. The participant is hooked up to an EEG. What brain waves
guajiro [1.7K]

Answer:

The correct answer is option b. "Alpha eventually replaced by theta".

Explanation:

Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.

Advantages of constant body temperaure
Leya [2.2K]
Proteins function optimally at a specific temperature. So if you get too hot or too cold, biochemical reactions in your body start to function less well. If the situation becomes extreme enough, they can cease to function well enough to sustain life. 

Warm-blooded animals have an advantage over cold-blooded ones in that their bodies automatically try to maintain the optimal termperature for things in their bodies to function. Cold-blooded animals depend on the environmental temperature to do this for them. That's why reptiles are very sluggish when they're cold, but will "wake up" when they get warm. 

The cost to this benefit is that metabolically, warm-blooded animals require a lot more fuel to run their bodies. It's very energy-intensive to maintain a constant body temperature. Cold-blooded animals require far less fuel than warm-blooded ones relative to their size. 

The way that proteins operate in a specific temperature is also true of the pH in your body which is also very tightly maintained.

Intrusive igneous rock bodies are called ?
vesna_86 [32]
Large bodies of magma that solidify underground before they reach the surface of the crust are called plutons. Coarse-grained intrusive igneous rocks that form at depth within the earth are called abyssal while those that form near the surface are called subvolcanic or hypabyssal.
