They create a different substance because on the periodic table each substance has a certain amount of protons and if you add or take away protons and/or electrons it will create a different substance. For Example Nickel has 28 protons but if you add 2 more you get zinc and that has 30 protons. Another Example is
what if you have Titanium which has 22 protons and take away 2 you get Calcium which has 20 protons.

Answer:
The reason hydrogen bonding occurs is because the electron is not shared evenly between a hydrogen atom and a negatively charged atom.
Explanation:
Hydrogen in a bond still only has one electron, while it takes two electrons for a stable electron pair. Any compound with polar covalent bonds has the potential to form hydrogen bonds.
<u>Answer</u>:
The term for the ability of muscles to be slightly contracted at all times to be ready to act is Muscle tone.
<u>Explanation</u>:
Regular partial contraction of the muscle or can be said as its resistance power to stretching during the resting phase. It helps in maintaining the posture of the body. The muscle tone occurs due to the hypotonia. This happens as the muscles depends upon the motor nerve signals which can be disrupted at the brain level, spinal cord or may be due to damage of muscle nerve. It can be measured with the stiffness which acts as a resistance to that of the passive movement.
Starting with a newly divided cell, the correct sequence for the human cell cycle phases are interphase followed by mitosis and then cytokinesis.
Interphase of the cell cycle does not involve any cell division. It is a period of growth and replication of the nuclear DNA. The cell prepares for the division in this stage. Interphase is further divided into the G1, S and G2 phases. Mitosis is the next phase of the cell cycle which involves the division of the cell in order to form daughter cells. Mitosis is further divided into the prophase, metaphase, anaphase and the telophase. Cytokinesis marks the end of the mitosis and this is where the cell actually separates to produce two daughter cells.
