Day and night sunrise and sunset is based on the rotation of earth on its axis

so basically it would be Day, rotation is a spin of the earth itself. it takes 24 hours for a full rotation. a year is a revolution of the Earth going around the sun.

Over a long period, how might living things adapt to increased carbon dioxide levels and global warming?

SCORPION-xisa [38]

Yes. We could be done for if it is anthropogenic and if it is not being caused by CO2 as we are lead to believe. CO2 may not be the only anthropogenic cause (if it is a cause).

If climate change is due to weather engineering by chem trailing in conjunction with ionospheric heating, then it could cause serious illness to our species.

The use of the electro-magnetic spectum and radio waves by ionospheric heaters, could cause genetic damage as well as infertility. Whether other sources of RF/EMF also play into weather manipulation and control is unclear. Whether the use of ionospheric heaters contributes to climate change is unclear, but it intuitively seems likely. Creating a sustaining a plasma in the ionosphere may heat up more than the ionosphere and it may have an impact on the weather.

We do not know what chemicals are being used to obscure the sun, create clouds, perhaps create rain and wind, (nor why) and therefore we do not know if those could also contribute to infertility or genetic damage when they finally wash out of the sky. We do not know if the chemicals can be absorbed through the skin, or what happens to us when we breathe them, or consume them in our drinking water or in the food we eat. Higher levels of certain metals have been measured in the soil after chem trails. It is difficult to know which tests to use to test for all the chemicals which can be used.

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. Action potential.

2. neurons that detect chemicals such as those found in food. Chemoreceptors.

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

4. the structure that gives the response to an environmental change. Effector

5. neurons that detect electrical fields. Electroreceptors.

6. secretion of hormones into the blood stream to affect distant processes. Endocrine.

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.

A carbohydrate molecule is (2 points) a macromolecule made of amino acids that provides structure for a cell and is not soluble

Sonja [21]

Carbohydrate consists as the name as of carbon and hydrogen and oxygen in the same ratio as water (hydra). Another name for carbohydrates would be saccharides... this is for an example glucose, ribose and so on... and we use fx glucose in cellular respriation.

A carbohydrate is a biological molecule consisting of carbon, hydrogen, and oxygen
