Answer:
Solution : Combustion of Liquefied Petroleum Gas (LPG) is a chemical change. Because it is an irreversible reaction and new products, carbon dioxide and water vapour are formed and lot of heat is also produced during the reaction.
Answer:
The answer is not in any of the options and is the following:
to eliminate any remaining Hfr cells.
Explanation:
In a medium that has a streptomycin antibiotic it is used to kill Hfr donor cells after the conjugation is interrupted. This is entirely due to the streptomycin sensitivity allele (str-s) which are found in Hfr strains. The presence of the streptomycin resistance allele, located in the receptor, is used for the specific destruction of Hfr donor cells after conjugation occurs.
He is WRONG
Explanation:
Any atom at the ground state has its orbital levels fill from the bottom (close to the nucleus) – up. The inner orbitals are of lower energy state and fill first because the atoms ‘likes’ to exist in the low energy and more stable state. Only when the atom is in an excited state do some of the electrons in the lower orbital levels shift to higher unfilled orbitals.
Answer:
C
Explanation:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
Answer:
__Rigor mortis__________ is caused by the lack of adenosine triphosphate (ATP) to the muscles
Explanation:
The rigor mortis corresponds to the stiffness of the muscles (they cannot contract or elongate) due to the lack of ATP, where I fixed the bridges between actin and myosin. This event happens when the oxygen transporting organs stop working.
