Answer:
All the options are correct except "has 7 electrons"
Explanation:
The correct answer to the question above is heat. Most of the energy from a lower trophic level is converted into heat. When an organism from a higher trophic level consumed an organism from a lower trophic level, it is mostly heat that is being converted to.
Answer:
Below
Explanation:
This is a single replacement/displacement reaction! This is the "formula" for single replacement : A + BC = AC + B
Answer:
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. ... Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Explanation:
Answer:
Atomic size decreases from left to right in the Periodic Table.
Explanation:
s you move from left to right, the nucleus gains protons.
This increases the positive charge of the nucleus and its attractive force on the electrons.
At the same time, electrons are added to the atoms as you move from left to right across a period.
These electrons reside in the same energy shell and do not offer complete shielding.
The effect of the increasing proton number is greater than that of the increasing electron number.
As a result, the valence electrons are held closer to the nucleus, and the atomic radius decreases.
