Answer:
97%
Explanation:
PKU is caused by a recessive mutation, which means that affected individuals are homozygous and recessive (<em>tt</em>).
<u>The frequency of genotypes according to Hardy-Weinberg equilibrium is:</u>
where p is the frequency of the <em>T</em> allele and q is the frequency of the <em>t</em> allele.
Affected individuals are 1 in 4500, which means the frequency of <em>tt </em>genotype is 1/4500.
If the population is in Hardy-Weinberg equilibrium,
The sum of the allele frequencies adds up to 1, therefore:
p + q = 1
p= 1 - q
p= 1 - 0.015
p= 0.985
The frequency of the TT genotype (homozygous wild-type individuals) will be:
97% of the population will have the homozygous wild-type TT genotype.
An answer might be - <span>Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.

Answer:
Atmosphere and geosphere is the part of the earth which is utilized in the nitrogen cycle.
Explanation:
In nitrogen cycle, the nitrogen which is present in the atmosphere comes down to the earth surface through rainfall. This nitrogen is absorbed by the earth and taken by roots of plants. Some amount of nitrogen is taken by many bacteria such as denitrifying bacteria which converts the soil nitrogen into atmospheric nitrogen and the nitrogen goes again to the atmosphere.
