Answer:
B. He has no E alleles.
Explanation:
In order for the boy to have an attached earlobes phenotype, he must have no E alleles, because the E is dominant. So his genotype must be ee. If he has even just a single E allele (like Ee) he will have detached earlobes, because the dominant trait will mask the expression of the recessive trait.
Why not A or D: Heterozygous Ee (one of each allele) would result in detached earlobes.
Why not C: If he has no recessive alleles, EE, he would have detached earlobes.
Sedimentary rocks are made from eroding other rocks and they are deposited on other rocks, they are younger than the underlaying rocks hence could only be formed on older underlaying rocks. If u have any more questions feel free to ask!
1) The process arrow A represents is photosynthesis.
2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.
3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.
I hope this makes sense. Hope this helps! :)
