MCA Unified Science: Biology - General Exam Info Sample Questions

Some believe thimerosol in vaccines causes autism. What can we conclude from this graph?





Correct Answer:
no relationship between thimerosol and autism can be seen.


the question presents a common concern about the safety of vaccines, specifically focusing on the use of thimerosal, a mercury-based preservative historically used in some vaccines. the concern is that thimerosal might be linked to autism, a hypothesis that has aroused considerable public debate and research. the correct answer to the question, based on the information provided by the graph, is that "no relationship between thimerosal and autism can be seen."

the graph in question is derived from an epidemiological study that examined the rates of autism following the removal of thimerosal from vaccines in 1992. this study is significant because it provides empirical data over a period following a change in vaccine formulation specifically aimed at addressing concerns about thimerosal. if thimerosal were a contributing factor to autism, one would expect to see a noticeable decline in autism cases after its removal. however, the study's findings, as published in the journal pediatrics, indicate that the incidence of autism did not decline but instead continued to increase sharply. this suggests that factors other than thimerosal are driving the rise in autism diagnoses.

the study’s findings are crucial for public health communication, as they help clarify the misinformation regarding vaccine safety. the persistence of autism incidence growth despite the absence of thimerosal challenges the hypothesis that thimerosal is a causative factor in the development of autism. such results underscore the importance of basing public health policies and parental decisions on robust scientific evidence rather than anecdotal associations.

it is also worth noting that the continuous increase in autism rates could be influenced by factors such as improved awareness, broader diagnostic criteria, or better reporting practices rather than an actual increase in the condition's prevalence. these factors were not directly addressed by the study but are commonly recognized in the scientific community as contributing to rising autism diagnosis rates over time.

in conclusion, the graph and the study it represents provide strong evidence against the hypothesis that thimerosal in vaccines causes autism. this finding supports the broader scientific consensus that vaccines are safe and effective and that fears of vaccines causing autism are unfounded. public health policies continue to be informed by such studies, ensuring that the benefits of vaccination are enjoyed widely, with minimal risks to public health.

Why would a recessive sex-linked trait be more common in males than females?





Correct Answer:
males are hemizygous for sex linked genes.


recessive sex-linked traits are more commonly observed in males primarily because males have only one x chromosome, making them hemizygous for the genes located on it. this genetic configuration is significant because it influences how certain traits are expressed in males versus females.

in humans and many other organisms, females have two x chromosomes (xx) while males have one x and one y chromosome (xy). sex-linked traits are those associated with genes found on the x chromosome. since males possess only a single x chromosome, any gene located on it will manifest, regardless of whether it is dominant or recessive. this is because there is no corresponding gene on the y chromosome to counteract or dilute the effect, a condition known as hemizygosity.

conversely, females, having two x chromosomes, can be either homozygous (having two identical alleles for a trait) or heterozygous (having two different alleles for a trait) for any gene on the x chromosome. for a recessive trait to be displayed in females, both of their x chromosomes must carry the recessive gene. if only one of the x chromosomes carries the recessive gene and the other carries a dominant gene, the dominant gene will mask the recessive one, making the trait not appear in the phenotype.

therefore, for a recessive sex-linked trait to be expressed in a female, she must inherit the recessive gene from both parents. however, a male only needs to inherit the recessive gene from his mother (since he inherits the y chromosome from his father), making the expression of such traits more common in males than in females. this difference in genetic expression due to the presence of a single x chromosome in males underlies why recessive sex-linked disorders, such as colorblindness and hemophilia, are more frequently observed in males than in females.
