You need to draw a punnet square:
_______
__|P | w |
|P |PP| Pw|
|w |Pw| ww|
So that means you'll have:
1/4 PP flowers, which are homozygous purple flowers
2/4 Pw flowers, which are heterozygous purple flowers
1/4 ww flowers, which are homozygous white flowers
So the ratio of purple to white flowers is 3:1
Answer:
A medida que la Tierra se enfrió, se formó una atmósfera principalmente a partir de gases arrojados por los volcanes. Incluía sulfuro de hidrógeno, metano y de diez a 200 veces más dióxido de carbono que la atmósfera actual. Después de aproximadamente 500 millones de años, la superficie de la Tierra se enfrió y solidificó lo suficiente como para que el agua se acumulara en ella.

Answer:
Ok, my first time answering a question!
Explanation:
Normally, your body uses cellular respiration to make ATP.
Cellular respiration needs oxygen to function.
When you exercise or exert yourself, you may begin to run out of oxygen.
Your body then begins fermentation.
Fermentation then makes it so energy can be released from glucose even though oxygen is not available.
Fermentation will also produce ATP, just like cellular respiration.
Hope this helps! :)
