The reactant that brings about the oxidation is called the oxidising agent, and that reagent is itself reduced by the reducing agent.
Oxidation occurs when a reactant loses electrons during the reaction. Reduction occurs when a reactant gains electrons during the reaction. This often occurs when metals are reacted with acid.
Oxidation is loss of electrons (OIL RIG). Therefore, an oxidising agent takes electrons from that other substance. Therefore, an oxidising agent must gain electrons.
Oxidation happens when an atom loses one or more electrons during a chemical reaction, meaning that its oxidation number increases. This is because the atom loses the negative charge of the electron, which is similar to gaining a positive charge, increasing the oxidation number.

Phylogenetic trees show the evolutionary pathways and connections among organisms. A phylogenetic tree is a diagram used to reflect evolutionary relationships among organisms or groups of organisms.
Answer:
In an experiment, the researcher needs to have a control group with an experimental group where both groups are identical in every way except that the controlled group does not gets the experimental treatment.
Sometimes, it is not possible to do a test or the experiment utilizing a controlled trial (due to ethical reasons or no practical method available). All things considered, a researcher may test a theory by making predictions about outcomes or patterns that ought to be found in nature if the hypothesis is right.
The answer is: "2A" or "IIA" or "2" or "II";
___________________________________
In which "II" stands for the Roman numeral representing the number: "2 (two)".

28. Part A.
A nucleic has a sugar group, a phosphate group, and nitrogenous base. A carbohydrate only has the sugar group units.
Part B
Nucleic acids make up the DNA and RNA which contain the genetic material for life.
Carbohydrates are used to provide energy to the cells.
Part C
Because all life require energy and this energy can be obtained from carbohydrates.
