The more energy needed, the higher the melting point or boiling point . As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points.
i would go with true.
Balamuthia mandrillaris is an amoeba that was discovered in 1986 in the brain of the baboon that dies in San Diego Wild Animal Park. This can be found in the soil and water, therefore it is freely living. It is known to cause the neurological condition known as granulomatous amoebic encephalitis. In a study published by National Center for Biotechnology Information, it has a case fatality rate of >98%. Majority of this case can be found in warmer regions that affects individuals mostly of Hispanic origin. Documented cases had been reported from the Latin Americas in significant number, followed by the United States, Asian regions and some in Europe. However, a specific number of cases worldwide may never be known due to the following factors: lack of awareness, poor diagnosis and a poor public health system.
It is still yet to be known if its a serious public health concern worldwide.
Other than contributing to potential increase in diversity of species in an ecosystem, exotic species have positive benefits like removing toxins from the soil, regulating erosion, and controlling undesirable species.
Answer:
sea floor spreading occurs at mid ocean ridges
Complete question:
A sample of butterflies contained 50% yellow-winged individuals and 50% black-winged individuals. In this species, wing color is determined by a single gene with two alleles, and the allele for black is dominant. Which of the following statements about the allele frequencies in the sample would most likely be true? Do not assume that this sample was obtained from a population in genetic equilibrium.
a)The frequency of the yellow allele is greater than that of the black allele.
b)The allele frequency of yellow is 3 times the allele frequency of black.
c)The allele frequency of yellow is twice the allele frequency of black.
d)The allele frequencies of black and yellow are equal.
e) The allele frequency of black is greater than the allele frequency of yellow.
2.Now assume that the population of butterflies sampled in question above is in Hardy-Weinberg equilibrium. Also assume that the sample is random and large enough that the allele frequencies in the sample equal the allele frequencies in the population. What is the frequency of the allele for a) yellow wings in the population? Assuming Hardy-Weinberg equilibrium in question 1, what would the correct answer be and why?
Answer:
- a)The frequency of the yellow allele is greater than that of the black allele.
- f(b) = q = 0.71
