Answer:
E, P, N and P, E, P, E, N, N and P
Explanation:
I am pretty sure the answers would go like this (in the order you have here):
1. Electron (they have a negative charge)
2. P (The atomic number is determined by the number of protons)
3. N and P (The atomic mass is determined by how many Neutrons and Protons there are in the atom)
4. Electron (they are usually involved in bonding)
5. Proton (they have positive charge)
6. Electron (ions are created when an atom has gained or lost electrons)
7. Neutron (they are neutral)
8. Both Neutrons and Protons (they stick together inside the nucleus)
I am not entirely sure why the atomic number determination has 2 blanks since it is only determined by protons, but I hope this helps. I havent studied this for a while but those are the best answers I can provide and have checked them with my books so I hope they are correct. Good Luck!

Answer:
Independent
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Hence, independent variable describes the variable that is changed to test the prediction.
Answer:
PCR is a tool used in molecular biology and Recombinant DNA is a technology, while developing technology various tools are used, for example our case the tools are vectors, ligation and Restriction digestion enzymes etc. PCR is the abbreviation for polymerase chain reaction. It is similar to recombinant DNA technology in that both have the ability to sequence DNA.
Answer:
The correct answer to the question: The argument above assumes which of the following? Would be, B: Overgrazing by rabbits does not pose the most significant current threat to the bilby.
Explanation:
The argument here states that there is a problem with a species of animal, a rabbit, which was not indigenous to Tambor Island and which has become a real threat, especially to agriculture. The government´s idea to deal with the issue is to use a virus to infect the rabbits and eliminate most of these invaders from the habitat, but with the least possible impact on other aspects of the life on the island. However, there is a problem that ensues from the proposed solution and that is that wildlife in the island may be placed in danger with the chance that the virus may infect it, particularly an endangered species called the bilby. From all the arguments given in here, the one that is assumed does not pose a real problem, and therefore does not have a negative impact given the situation, is the overgrazing by rabbits, as this does not affect either agriculture, nor the survival of the bilby. The only thing that does pose a threat to the survival of this endangered species, and a direct one, is the solution proposed by the government.
