Answer: The independent variable is the different amount of water. The correct option is A.
Explanation:
A variable can represent age, a person, or an entity that can be measured. In statistics, it is simply defined as an attribute of an object to be investigated. There are different types of variables these includes:
--> Dependent variable and
--> Independent variable.
Dependent variables are simply the variables that are affected by the changes that occurs in the experiment. From the experiment they should include:
--> the height of the plant,
--> the size of the plant,
--> the number of leaves
---> if the plant survived or not (dead).
Independent variable are the variables that are changed in the experiment. A good example from the pea plant experiment is WATER. It is the aspect that is used to alter the dependent variable which is the height of the pea plant. I hope this helps, thanks!
Answer:
A
Explanation:
choice C would be tempting to choose but the the amount of molecules of a compound most of the time only 1 unless stated otherwise. The more obvious answer is that you can find the amount and kind of atoms in the compound.
The correct answer is
DNA polymerase is the enzyme that catalyzes the addition of a nucleotide onto the 3' end of a growing DNA strand. DNA polymerase adds nucleotides one by one to the 3’ end of the growing DNA chain, incorporating only those that are complementary to the “old” DNA strain.<span>The addition of nucleotides requires energy which comes from the nucleotides themselves (phosphates).</span>
Answer:
The correct answer is: Maggots do not arise spontaneously but from eggs laid by adult flies.
Explanation:
According to the experiment Redii, The maggots are present only in the open jar not in the sealed jar. The adult flies can not go in or out of the jar to the meat and can not lay the eggs on meat whereas in an open jar the adult flies can easily get in the jar and lay the eggs on meat.
On the basis of the above response and explanation, it can be concluded and hypothesize that maggots do not arise spontaneously but from eggs laid by adult flies.
