Answer:

C. 48

Explanation:

Simple thing to bear in mind; The number of neutrons is equal to the Atomic number - the Mass number. Because the Atomic number tells you the number of Protons, whilst the mass number tells you the number of both PROTONS and NEUTRONS. So 84 - 36 is 48. You have 48 neutrons

Answer:

Allopatric speciation

Explanation:

Speciation is the gradual process by which two different species are formed from a single species due to evolution.

Allopatric speciation will occur when the speciation is due to geographical isolation of a species to the extend it prevents or interferes with the gene flow. Therefore, the populations can not mate with each other and they evolve separately.

This is what happened to the fox species when they were separated by a mountain range.

weqwewe [10]
The term applied when water passes through a selectively permeable membrane from an area of high to low concentration is called osmosis. Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.

Iced tea's energy increases while the energy of the glass decreases.

<h3>What is energy?</h3>

Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other forms

Iced tea's energy increases while the energy of the glass decreases because the ice is getting warmer so the glass is also getting warmer. meaning that the glass is decreasing in energy while the ice tea is increasing in energy.

Hence, iced tea's energy increases while the energy of the glass decreases.
