Choose four elements from anywhere in the periodic table. Record their masses in the table. Explain how their masses relate to e

ach other and their positions on the table.

3 0
Hydrogen-1.01
Helium-4.00
Oxygen-16.00
Carbon-12.01

The mass of each element comes from the total number of protons and neutrons.

Elements are organized on the periodic table by their atomic number which is their number of protons

This means that further you go down a group (column ) or to the right across a period (row) the larger the atomic number and subsequently mass number will be.

Hope that helped!

Which sense is not affected by damage to the thalamus?
Nady [450]
Which sense does not go through the thalamus?<span>One, this is the only sense that does not travel to the thalamus before accessing the fore brain. The thalamus, if you remember, is the relay center for all sensory signals. Nearly all receptors send signals through the thalamus first, which then sends the signals to the proper areas of the brain for perception</span>

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.
