The end of the world as we know it could come in any number of ways, depending on who you ask. Some people believe global cataclysm will occur when Earth's magnetic poles reverse. When north goes south, they say, the continents will lurch in one direction or the other, triggering massive earthquakes, rapid climate change and species extinctions.
The most dramatic changes that occur when the poles reverse is a very large decrease of the total field intensity,
Earth's magnetic field takes between 1,000 and 10,000 years to reverse, and in the process, it greatly diminishes before it re-aligns. It's not a sudden flip, but a slow process, during which the field strength becomes weak, very probably the field becomes more complex and might show more than two poles for a while, and then builds up in strength and [aligns] in the opposite direction.
Answer:
A.) DNA is a double helix, and RNA is a single strand.
C.) DNA is involved only in transcription, and RNA is involved in both transcription and translation.

Answer:
100% pea plants will be with green pod and with round seeds.
Explanation:
As per the question given, a homozygous pea plant having green pod (gg) and round seeds (WW) is crossed with a pea plant having homozygous green pod (gg) and heterozygous round seeds(Ww). A pea plant homozygous for green pod and round seeds (ggWW) will produce one type of gametes having alleles (gW), whereas, a pea plant homozygous for green pod and heterozygous for round seeds(ggWw) will produces two type of gametes having alleles gW and gw. On crossing, phenotypically, they will produce all pea plants with green pod and round seeds. But genotypically, 50% of green pod pea plants with homozygous round seeds and 50% of green pod pea plants with heterozygous round seeds.
