Answer: Electrons positioned closer to the nucleus have a greater attraction to the protons and are more likely to be discharged from the atom than electrons farther away.
Explanation: The electrons being negatively charged repel each other due to like charges. The protons being positively charged are attracted towards the negatively charged electrons.
The electrons which are near to nucleus are more tightly held by the protons and thus are more difficult to remove from the atom. The electrons which are far from the nucleus are less tightly held and are easily removed from the atom.
I would say b or c but c is the best answer in my opinion
To study the Blood-Brain Barrier requires that research involves the use of subjects such as guinea pigs, rabbits, or even humans. The research would involve conducting different treatments with different substances to check which their movement or effect on this barrier. The research may also involve opening up or severing of the brain for analysis. This, will, therefore, raise ethical issues on the use of human subjects, and the respect for human dignity and bodily integrity. The research would have to comply with the ethical rule of non‐maleficence which may limit the frontiers of the research hence limit its success.

Increasing the concentration of carbon dioxide increases the rate of photosynthesis, as there is a greater supply of it that can be used. Of course, you can only add so much carbon dioxide before the plant can’t perform photosynthesis at an any faster rate. Increased carbon dioxide concentration will increase the rate of photosynthesis until it is no longer the limiting factor in the reaction.
