Error is the amount of imprecision or variation in a set of measurements. It is expressed as a percent error. So the statement is true! Hope this helped!
Answer:
the rats weight loss
Explanation:
<em>The dependent variable would the weight of the rats.</em>
<u>The dependent variable is the variable whose value is dependent on another variable during an experiment. It is the actual variable set out to be measured or tested by researchers. The effect of the manipulation of the independent variable is measured on the dependent variable.</u>
Hence, in an experiment aimed at determining whether a new diet medication will help rats to lose weight, the weight loss by the rats would be the dependent variable.
Answer:
As image is not provided,let's discuss about ecological succession.
Explanation:
Ecological succession can be described as the development of a community from its pioneer to climax community. There are two types of ecological succession:
Primary ecological succession: This type of succession occurs in lands where there was no life before or in lands where signs of life have completely been removed like an lava eruption. The rocks in this land are broken down and slowly, pioneer species begin to grow.
Secondary Succession: This type of succession arises after a natural disaster like fire etc or after any human activity has wiped out the previous community which survived on this land. smalls shrubs and grass starts to grow back on this land, which is replaced by the intermediate species and finally with the climax community.
It depends on the energy released by radioactive decay of
uranium and other heavy long lived isotopes in the Earth's core and the
internal heat of the Earth is produced by the original heat of formation that
resulted from accretion and gravitational contraction.
All elements have certain characteristics that are summarized on the periodic table. These characteristics include the element's symbol, atomic number, and atomic mass. You will learn how the number of protons in an atom relates to an element's atomic number, and explore how isotopes affect the atomic mass.
