Answer:
<em>Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.</em>
At the bottom of the pyramid would be autotrophs. An example of this is a tree.
Answer:
5 is the best conclusion draw for Africa
Answer:
a) The genotype of her father = "aa".
The genotype of her mother = "Aa".
The genotype of Sally is "Aa".
b) 1/2
c) 1/2
Explanation:
a) Sally's father has alkaptonuria. So, the genotype of her father is "aa". Her mother is normal. Since her brother is affected by the disease, he should be homozygous recessive (aa). This means that the mother also has one copy of "a" allele and is heterozygous dominant (Aa). A cross between Aa (mother) and aa (father) would give 50% affected progeny with "Aa" genotype. So, the genotype of Sally is "Aa".
b) The genotype of her mother= Aa
The genotype of her father = aa
Aa x aa = 1/2 Aa (affected): 1/2 aa (normal)
So, if Sally's parents have another child, there is a 1/2 probability that this child will have alkaptonuria.
c) The genotype of Sally = Aa
Genotype of the man Sally marries= aa (since he is affected with alkaptonuria)
Aa x aa= 1/2 Aa (affected): 1/2 aa (normal)
There is a 1/2 probability that their child will have alkaptonuria.
