Because people throws trash into rivers and stuff and they flow down into the ocean and makes it unclean
Answer:
F1= All Yy
F1= All yellow
F2= 1/4 YY: 1/2 Yy: 1/4 yy
F2= 3/4 yellow: 1/4 green
Explanation:
The allele for the yellow-colored seeds (Y) is dominant over the allele that imparts green phenotype (y). A cross between two pure breeding yellow seeded and green seeded plants would obtain all yellow seeded plants in the F1 generation. Self-pollination of F1 progeny would obtain F2 generation in following phenotype and genotype ratio:
Phenotype ratio= 3/4 yellow: 1/4 green
Genotype ratio= 1/4 YY: 1/2 Yy: 1/4 yy
Answer:
A. Done some research
Explanation:
You need to have an idea of what you are working with. So, to make a good hypothesis, you need to have an idea on what the experiment is. The hypothesis comes before you design a procedure or even start working on the experiment.
And BTW, you can't logically do option D. Science doesn't work that way. The Scientific Method is used to collect observations and evidence and piece them together to come to a conclusion.
Hope that helped. :)
