Experimental investigations<span> involve a process in which a "fair test" is designed and variables are actively manipulated, controlled, and measured in an effort to gather evidence to support or refute a </span>causal relationship<span>. Experimental investigations have a control group which does not receive any treatment. A classic example is "What is the effect of light color on plant growth?" In this experiment, the variable color of light is changed by the student. The student may compare red light to green light to natural light.
hope i helped ^_^</span>
Answer:
well idk but i will take the points
Explanation:
Is there any answer choices?, Im very confused on what to answer
The theory that describes the motion and force driving earth's plates is Plate tectonics
Explanation:
Plate tectonics states that the outer shell of the Earth is divided into plates that glide and move over the mantle which is the surface of the earth.
The mantle is the rocky inner layer above the core of the Earth.
Plate tectonics helped the geologists to explain how continents could move around the planet.
There are 9 major plate tectonics , namely North American, Pacific, Eurasian, Australian, African, Indo - Australian,Indian South American and Antarctic. These plates have been named after the land form found on them.
The correct answer is A. It is uniform in composition and the parts that make up the mixture can be separated from one another through physical means.
Explanation:
In a homogeneous mixture, components are completely integrated, which means the final substance is uniform and the parts that compose it are not separated. This occurs in milk because this integrates uniformly water, fat, among others, and these elements cannot be observed separately.
Moreover, in mixtures, components can be separated through physical means; for example by heating the substances. This applies to milk because if it is heated water evaporates, and therefore can be separated.
