Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).
Answer:
C. To confirm that the alternative fuel is cleaner than fuels currently used
Explanation:
The current fuels from mining, cutting down trees and even transportation is bad for the atmosphere. These fuels cause climate change which could potentially bring a lot of dangers. The reason scientists would conduct research on a newly alternative fuel is so that the fuel would be a lot more cleaner which could prevent the dangers that are to come.
True B) African-Americans fought for both the British and American sides during the Revolutionary War. Both sides offered them freedom or money for fighting.
Answer:
What hypothesis were the researchers testing in this study? The disease-suppressive properties of soils are due to the activities of soil microorganisms.
Explanation:
Scientists wanted to know if microorganisms protect against crop disease. Researchers tried to figure out if microorganisms were responsible for the protective effects of disease-suppressive soils. The spil layer surrounding plant roots is called. When plants are attacked by fungal or bacterial pathogens, soil from the rhizosphere may protect them from future attacks.
