Students hypothesized that adding lactose to a sixth test tube would produce the greatest amount of carbon dioxide.
This is because lactose is a sugar molecule that is the food source for the yeast.
Fermentation is a metabolic pathway that occurs anaerobically, meaning in the absence of oxygen (O2). It includes the process of glycolysis with some extra reactions which make alcohol.
In this case, the dependent variable is the rate of respiration, the independent variable is the type of plant (either fruit or tomatoes), whereas a fixed variable may be the temperature.
<h3>What is a dependent variable?</h3>
A dependent variable is any type of experimental condition that is modified during the experiment.
Conversely, independent variables do not change along the experimental procedure (e.g., type of plant).
Finally, a fixed variable, also known as a control variable, is any condition that remains stable during the experimental procedure (in this case, for example, room ambient temperature).
In conclusion, the dependent variable is the rate of respiration.

Explanation:
1. Earth is 13 million years older than moon... Moon is 4.53 billion years ago and earth is 4.543 billion years ago.
Much younger than earth.
2.moon has small iron core or lacks sizable iron core.
3 galaxies not considered in solar system bcoz
solar system is the part of milky way galaxy..
4. Hydrogen and helium
5. Venus bcoz it is closest to Sun.
The answer is B, because layers mix better at the poles.
Answer:
Option D is correct.
Explanation:
Option a) given in the option that if promoter is altered it will inhibit transcription which is the process by which information present in DNA converted to mRNA which require RNA polymerase which bind to promoter site so if promoter is altered RNA polymerase will not bind so transcription will be inhibited but above question is asking about inhibition of translation due to binding of miRNA-delta molecule to Q mRNA so this option can be eliminated.
Option b if miRNA binding site sequence is altered miRNA molecule will not be able to bind to Q mRNA so translation will not be inhibited hence option b is incorrect
Option c translation of Q mRNA is inhibited when miRNA - delta is present not absent
So option c can be eliminated
Option d if miRNA binding sequence is altered miRNA molecule if present will not bind to Q mRNA hence translation of Q mRNA will occur & not inhibited
Hence option d is correct
