Selective Breeding is a type of process in which humans use animal and plant breeding to 'selectively' develop something of their needs. It is an artificial process and has its own advantages and disadvantages ;)
Answer :

Explanation : To find density, we can use the formula as given below;
density ρ =

Here, we have the mass as 89.6 g and the volume is ,
on calculating we get,
This means that the density of the copper sample is
Answer: The correct answer is: C The are the same except osmosis specifically and only involves water.
Explanation:
Osmosis is the process in which a solvent moves across a semipermeable membrane in order to dilute a concentrated solution and it ends up equalizing the concentration of the solution at both sides of the cell membrane.
On the other hand, diffusion occurs when particles move from an area of higher concentration to an area of lower concentration and it ends up equalizing the concentration.
So the main difference is the presence/ Lack of water in the processes.
In conclusion the correct answer is : C.
Answer:
The modern view of electric charge is that it is a basic property of atoms, the fundamental particles of which all matter is made. Atoms themselves are composed of three different types of particles—protons, neutrons, and electrons.
Explanation:
I would say, C. Because an controlled variable is an experimental element which is constant and unchanged throughout the course of the investigation.
