Answer: False
The variations in expression depends on how genes code for proteins
that would specify whether it will be dominant or recessive allele. Within a population, there may be a number of
alleles for a given gene and these differences
can cause variations in the protein that is produced. The change in protein
expression affect traits due to the variations in protein activity or
expression that produce different phenotypes.
<span>Moreover, individuals that have copies of
different alleles are known as heterozygous
and individuals that have two copies of the same
allele are referred to a homozygous. The expression patterns observed in
inheritance will depend on whether the allele is found on an autosomal
chromosome or a sex chromosome, and on whether the allele is dominant or recessive.</span>
The intrinsic rate of the atrioventricular av bundle is 40 to 60 beats per minute (bpm).
<h3>
What is the Atrioventricular (AV) and the intrinsic rate?</h3>
Atrioventricular (AV) can be regarded as the block that usually altered the interruption of impulse transmission between the atria to the ventricles.
And this have the 40 to 60 beats per minute (bpm) as the intrinsic rate.

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.
I’m pretty sure it’s the second one
I don't think the answer is A as that seems a bit drastic, I think it's C.
