Answer:
All the progeny had a purple flowers in F1 generation.
Explanation:
A plant that always produced purple flower suggest that the plant is homozygous for purple color(PP) and the plant that always produces white flower then it is homozygous for white flower(pp) trait.
So when Mendel crossed these plants he saw that all the offsprings had purple flower which shows that purple is the dominant trait and white is the recessive trait.
P P
p Pp Pp
p Pp Pp
Therefore in first-generation, all the plants produced purple color flowers.
I would help if I was in biology
The cells won’t be able to efficiently get what they need and that will disrupt processes such as cell respiration or photosynthesis. If you are talking about cell membranes, then the organisms won’t be able to function Bc the cell membrane compartmentalizes the cell to see that everything runs efficiently
Answer:
I think the answer is C
''Reusing plastic bags''
Explanation:
Removing carnivores from a forest has a great impact on a environment since the population of the herbivores will increases drastically and the dynamic equilibrium of the area will be greatly effected.
If we look at choice B '' Heating homes with fossil fuels'', this will also have a big impact on the earth since fossil fuels are non-renewable and take centuries to form. Heating homes with them will result in loss of fossil fuels.
Now let's look at choice D ''Adding heavy metals to the water supply''. Heavy metals are dangerous to the human health and even cause cancer. This will cause thousands of deaths and will also have a great impact on the global stability.
This leaves choice C ''Reusing plastic bags''. This will cause less pollution and less harm to wildlife but doesn't have any big threat to the global stability. As in changing the world population or causing deaths in large numbers.
so I think choice C is the answer
