Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.
The equivalence point of a titration is equal to its stoichiometric equivalents of analyte and titrant.
Depending on the concentration of titrant we could be adding little excess of it and this may result in persistence of color of solution. After continuous stirring for a while the excess titrant may react with dissolved CO₂ in air and thus decolorizing the solution.

The 2 main components of the internal energy of a substance are:
The internal energy is a sum of kinetic and potential energy.
E_k (total)=E_k(translational) + E_k(rotational) + E _k(vibrational)
Internal energy is the microscopic energy contained in a substance, given by the random, disordered kinetic energy of the molecules. Further it includes the potential energy between those molecules, and the nuclear power contained in the atoms of those molecules.
The internal energy of a system is extensive property. it's a state property. The exchange is independent of the path followed. Change in internal energy of a cyclic process is 0.
Internal energy is affected by factors including pressure, volume, and temperature. All the variables on this listing are state functions.

Answer: 2) Electron X absorbs energy when it changes to a higher energy level.
Explanation:
The electrons in an atom exist in various energy levels. When an electron moves from a lower energy level to a higher energy level, energy is absorbed by the atom. When an electron moves from a higher to a lower energy level, energy is released (often as light).
Answer:
energy to get the work done ig
Explanation:
