Natural air pollution comes from those known as wild fires, and volcanic smoke. If you wonder why well it's because of the smoke it contains and produces. Smoke is one of our biggest air pollution and it contaminates our atmosphere.
I'll provide pictures of natural air pollution..
Note:
These pictures don't belong to me.
I hope this helps.
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.
Answer:
the well be wind cell are used in isolated locations
Answer:
Seven segments
Explanation:
As given in the question -
After every twenty microseconds one reaction occurs i.e breakdown of polysaccharides.
This means that after every twenty microseconds the polysaccharides is broken down
The total time for this hydrolysis reaction is 
micro seconds
Thus , there will be six phases of division each after every twenty microseconds
After 1st twenty microseconds , total segments is equal to two
After 2nd twenty microseconds , total segments is equal to three
After 3rd twenty microseconds , total segments is equal to four
After 4th twenty microseconds , total segments is equal to five
After 5th twenty microseconds , total segments is equal to six
After 6th twenty microseconds , total segments is equal to seven
