In a nutshell, a chemical change produces a new substance, while a physical change does not. A material may change shapes or forms while undergoing a physical change, but no chemical reactions occur and no new compounds are produced. And for an explanation on how to see the difference Look for an indication that a chemical change occurred. Chemical reactions release or absorb heat or other energy or may produce a gas, odor, color or sound. If you don't see any of these indications, a physical change likely occurred. Be aware a physical change may produce a dramatic change in the appearance of a substance. This doesn't mean a chemical reaction occurred.
Answer:
On the basis of the given information, the six goldfish are taken in distinct sized aquarium to examine the influence of habitat space on the rate of survival of the fishes. The kind and amount of food, cleanliness, and temperature are maintained similarly.
Thus, with the help of the information one can state that:
A. The size of the aquarium is the independent variable.
B. The number of fish survived after six months is the dependent variable.
C. Water temperature, the kind of amount of food, maintenance, and cleanliness of aquariums are the controlled variables or the constants.
In the controlled experiments, there are dependent and independent variables. The independent variable will get modify generally and is compared to the control. The variable, which is determined in an experiment is considered as the dependent variable. It relies upon the independent variable of the experiment. The control group in an experiment is created similar in each circumstance in an experiment. The control group is the one, which is compared with the experimental group.
Answer:
No
Explanation:
because fermentation cannot occur without oxygen as a final electron acceptor.
True... examples: the spine helps you stay up right which would help for structure and the skull help protect the brain which would be protection

Explanation:
The formation of the mRNA from the template strand or anti-sense strand is known as the transcription.
The nucleotide in the mRNA is added in the same way as the DNA according to the Chargaff rules which states that A will bind to T and G will bind to C but instead of adenine in mRNA will add uracil.
On the basis of this, the mRNA strand will be-
template strand: 5' A T T G C G A A C T G C G A G G A C T T C- 3'
mRNA strand: 3'- T U U C G C T T G U C G C T C C T G U U G-5'.
