The
molecular clock tracks down nucleotide sequences for DNA or amino acids that
contain sequences of proteins. Scientists use this to deduce the time in
history where life forms possibly have diverged. This technique is also known
as a gene clock or an evolutionary clock.

Explanation:
Homozygous Red, or Homozygous Dominant: RR
Yellow fruit must be homozygous recessive, or else the yellow would show: rr
Plant 1 Genotype: RR
Plant 2 Genotype: rr
The punnet square is attached.
The Genotypic ratio is: 4:0 or just Rr because the offspring turned out to be 100% heterozygous.
The Phenotypic ratio is just red, because no other colors come out of the offsping.
Hope this helps :)
Population growth is difficult to predict because unforeseen events can alter birth rates, death rates, migration, or the resource limits on population growth
Such policies could have a significant effect on global fertility rates.

Answer: Secondary growth is the outward growth of the plant, making it thicker and wider. Secondary growth is important to woody plants because they grow much taller than other plants and need more support in their stems and roots. Lateral trimester are the dividing cells in secondary growth, and produce secondary tissues.
