Answer:
This is a math question not a biology question
The correct answer is: A) metabolic enzymes require vitamin cofactors, and affected individuals have significant nutritional deficiencies.
Garrod exanimated urine chemistry because he believed that it is reflection of systemic metabolism and disease. He wanted to understand disorders of metabolism such as alkaptonuria. By studying urine of mother that has disease and later her child’s urine he made a conclusion that it is inherited (Mendelian pattern of inheritance).
In the field of histopathology, the tissues to be observed under the microscope are cut in very thin slices. The thin slices make the tissue transparent, and thus, it becomes easier to observe the internal structures and accurately diagnose a disease. The tissues slices cut for the observation are generally not more than 3 micro meters in their thickness.
Hence, the answer is 'to make the tissues transparent and easier to observe'.
Answer:
p represents the frequency of the dominant allele (in decimal form) of a gene
q represents the frequency of the recessive allele (in decimal form) of a gene
These 2 alleles are different; one is dominant, one is recessive.
p^2 = the frequency of homozygous dominant individuals in the population (decimal form)
2pq = the frequency of heterozygous individuals in the population (decimal form)
q^2 = the frequency of homozygous recessive in the population (decimal form)
