Praxis Pennsylvania Grades 4-8 Subject Concentration: Science - General Exam Info Sample Questions

All of the following factors are involved in determining biotic potential EXCEPT:





Correct Answer:
how many offspring are male.


biotic potential refers to the maximum growth rate that a population can achieve under ideal conditions, where there is no competition for resources, and no limitations due to predators or diseases. it is a critical concept in population ecology, used to understand the capacity of a species to increase in number. several factors contribute to determining the biotic potential of a population. these factors include the age at which organisms begin to reproduce, the frequency of reproduction, and the number of offspring that survive to adulthood. each of these elements plays a crucial role in how quickly a population can grow under optimal conditions.

the age at which organisms start reproducing is significant because it marks the beginning of the possibility for population increase. species that mature early and can reproduce soon after birth will have a higher biotic potential compared to those with a later onset of reproductive maturity. similarly, the frequency with which organisms reproduce affects the biotic potential. species that can reproduce multiple times a year or have shorter gestation periods can increase their numbers more swiftly than those that reproduce less frequently.

moreover, the number of offspring that survive to adulthood is another vital factor. high survival rates among the young mean that more individuals can reach reproductive age, thereby contributing to the future population growth. this factor is particularly influenced by environmental conditions and the availability of resources that support the health and growth of the young.

however, the sex ratio of the offspring—specifically, how many of them are male—does not directly influence the biotic potential. while the sex ratio can affect the mating dynamics within a population, it does not inherently limit or enhance the population’s capacity to reach its maximum growth rate under ideal conditions. the biotic potential assumes an environment where all individuals have an equal chance to reproduce and contribute to population growth, making the sex of the offspring irrelevant in this context. thus, when considering the factors that determine biotic potential, the sex ratio of the offspring is not a relevant factor and is correctly identified as the exception among the options provided.

Which disease is caused by mercury poisoning?





Correct Answer:
minamata
*pminamata disease, also known as niigata minamata disease, is a serious illness caused by mercury poisoning. this neurological syndrome was first discovered in minamata city in kumamoto, japan, in the 1950s. the source of mercury was industrial wastewater from a chemical factory, which used mercury in its acetaldehyde production process. this toxic waste was dumped into minamata bay, where it contaminated the fish and shellfish that were a staple in the local diet. *pas a result, residents who ingested the seafood from minamata bay began to exhibit severe neurological symptoms, which include sensory disturbances, numbness in the hands and feet, muscle weakness, narrowing of the field of vision, and damage to hearing and speech. severe cases presented with insanity, paralysis, coma, and even death following the onset of symptoms. the disease was not only a tragedy health-wise but also socially and economically devastating for the affected communities, who relied heavily on fishing. *pthe minamata disaster is one of the most notorious cases of mass poisoning in modern history and led to widespread changes in regulations regarding environmental pollution and chemical handling. public outrage over the suffering of the victims and the initial denial by the company responsible led to a greater environmental awareness worldwide and the establishment of stricter standards for industrial waste management. *pin contrast, itai-itai disease, another infamous poisoning incident in japan, resulted from cadmium poisoning. hepatitis and cyanosis are unrelated to mercury exposure; hepatitis is generally caused by viral infections affecting the liver, and cyanosis is a symptom characterized by a bluish or purplish coloration of the skin due to low oxygen levels in the blood, often associated with heart and respiratory diseases. *pthus, the correct answer to the question of which disease is caused by mercury poisoning is minamata disease. this response not only highlights a specific environmental and public health issue but also underscores the importance of responsible industrial practices and the impact of environmental contamination on human health.
