Both fish seen here are African zebra cichlids. They have two color alleles. The allele for blue coloration is B, while the gene for orange coloration is O. A fish that has both types of alleles will be marbled orange and blue. This type of fish is not shown in the picture. Suppose that a male with genotype BO mates with a female that is also BO. What percentage of each PHENOTYPE will their offspring have? Question 7 options:

25% blue; 50% marbled; 25% orange

50% blue; 50% orange

50% BB; 50% BO

25% BB; 50% BB, 25% BB

25% BB; 50%BB, 25%BB

Explanation:

no answer

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
