An error is that the scientist did not control their variables. They had one group of people playing the game at 6, and another group playing at 12. This means that other things might have affected the scores other than what was being tested, which was caffeine.
Answer:
There are several environmental factors that causes changes in the ecosystem and the population of that area such as invasive species, extreme weather, land use change, pollution and disease.
Lets take invasive species as environmental factor. Introduction of invasive species can cause a huge change in the ecosystem and affects the native population in that area. it increases the competition for food resources and decreases the survival rate of their preys.
For example: Water hyacinth (Eichhornia crassipes). It is an invasive plant species that has very bad impact of native population as well as other population, like it reduces biological diversity, oxygen loss, decreased phytoplankton productivity, eliminate plants that animals use for nesting, and alter animal communities by blocking access to the water.
Thus invasive population can affect population by reducing biodiversity, water shortages, decreasing availability and quality of key natural resources, disturb the food chain and can cause natural calamities.
Invasive species affect the resources that native species are using and that decreases the carrying capacity of the native population as it disturbs the whole food chain.
Answer:
Gene: The hereditary material made up of alleles.
Alleles: The alternative forms of a gene.
Dominant: An allele or trait that masks the effect of recessive allele or trait.
Recessive: An allele or trait that gets suppressed by the dominant allele or trait.
genotype: The genome of a particular organism of the genes which make up an organism.
phenotype: The physical traits or characteristics of an organism.
test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.
law of independent assortment: Alleles of different genes get assorted independently into gametes.
law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.
product rule: Independent evens can be calculated by multiplying the independent probabilities.
Addition rule: The probability which shows that one event would occur in a mutually exclusive event.
co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.
incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.

Explanation:
Guessing you mean "impulse".
It means to have a sudden strong desire to do something or a small amount of energy that moves from one area to another.
