Check points throughout the cell cycle that determine when the cell should begin the next phase
The <em><u>MESOSPHERE </u></em>is the coldest layer and the hottest layer is <u><em>THERMOSPHERE </em></u> is the hottest layer in the atmosphere.
A. The hemisphere of the Earth is tilted more toward the Sun.
Answer:
The correct answer is A. 3O₂ + 2Al → 2AlO₃
Law of conservation of mass states that mass can nether be created nor destroyed in a closed system or chemical reaction i.e. the total mass of the matter always remains the same throughout the chemical or physical change.
For example, in the given reaction 3O₂ + 2Al → 2AlO₃ the total mass of the reactants is equal to the total mass of the product.
Mass of oxygen = 16 x 3 = 48 AMU
Mass of aluminium = 2 x 27 = 54 AMU
Total molecular mass of the reactants = 102 AMU
Total molecular mass of the product = 2 x 27 + 6 x 8 = 102 AMU.
Hence, the total mass of the matter remains the same.
For this, you need to use Punnett squares.
You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.
AABBCc divided like ABC and ABc.
Aabbcc divided like Abc and abc.
Now you can cross them, and all probabilities will be:
AABbCc, AaBbCc, AABbcc and AaBbcc
So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc
