Answer:Answer:
For 1: The correct answer is Model 1, 2, and 4.
For 2: The correct answer is Option 1.
Explanation:
For 1:
An element has 3 subatomic particles: electrons (E), neutrons (N) and protons (P).
Atomic number is defined as the number of protons or number of electrons.
Atoms having same number of protons are same. From the given models, Model 1, 2 and 4 have 2 protons with different neutrons. Hence, these models belong to same element.
For 2:
A compound is defined as a substance in which two or more types of elements combine in a fixed ratio. For Example: is a compound made out of atoms of carbon and oxygen.
Hence, the correct answer is Option 2.
The alteration of serial numbers belong to the "Recovery of stolen electrical goods" phase.
NC, sterilization or removing a serial range is usually charged as a secondary offense aboard a thievery offense. Generally, a person who alters or removes a serial range is doing this to hide the actual fact that they either scarf the property or received transferred possession. As such, there's a public interest in toilsome people who have interaction during this activity.
Answer:
Pyruvate kinase is the important enzyme that catalyzes the conversion of phosphoenol pyruvate into the pyruvate in the glycolysis cycle. This step generates the ATP molecule.
The regulation of the pyruvate kinase is done by the allosteric regulation and fructose 1,6 biphosphate activates the pyruvate kinase. This regulation is important as it control the metabolites present in different organs. The metabolites like fructose, galactose enters in the glycolysis from the liver after the particlar step of glycolysis.
Answer:
