Answer:Texas cichlid (Herichthys cyanoguttatus)
Explanation:
Texas cichlid (Herichthys cyanoguttatus, ex. Cichlasoma cyanoguttatum) is a large, good looking and at that rather aggressive cichlid fish. In the wild it inhabits in rivers of Texas (for example, Rio Grande, due to which the fish got its name Rio Grande cichlid) and in North Mexico.
I think C would be correct
Answer:
amount of copper
Explanation:
<em>The independent variable would be the amount of copper fed into the experimental rats.</em>
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
<u>Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.</u>
Nitrogen and oxygen make up about 99%of the atmosphere. I'm not sure if it will help! But thats all I know.
ANSWER:
Electromagnetic energy is monitored by scientists forecasting future space weather
EXPLANATION:
Electromagnetic energy has such type of waves which propagate or radiate through space, carrying photons. Electromagnetic energy has radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays.Space weather includes any activity happening in space that might affect Eath's environment.Space weather can interrupt mobile signals,air communications and can damage our satellites.So Electromagnetic waves are monitored to control all the above situations.
