Answer:
The answer is statement 3: Smaller class size is related to better academic performance
Explanation:
An hypothesis is an assumption taken to be true for the purpose of investigation.
Unlike statement 3, the statements 1, 2 and 4 are more like facts, since they are definite.
Thus, statement 3 tells of an assumption, and is an hypothesis

Answer:
Explanation:
i) Allosteric control
-Allosteric modulation is a mechanism whereby the activity of an enzyme is either stimulated or inhibited by a compound that binds to a site, called the allosteric site, that is dimensionaly different from the enzyme’s active site
ii) Covalent modification
-Covalent modification of enzymes, as illustrated by the addition (or removal) of phosphates, is a general mechanism for changing the activity of enzymes.
-Enzymes that transfer phosphate groups to other proteins are called protein kinases and regulate such diverse activities as hormone action, cell division, and gene expression.
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
