Solution to both questions are given below. Feel free to get back in fineness in case the solution isn't clear.
In a density dependent population the birth rate decreases as population density increases. Consequently, the death rate increases with the density, Hence answer is option C.
Frequency dependent selection depends on the allele frequency, how common or how least common it is in the population. Hence it selects both the extremes. Fitness depends on how common or how rare the phenotype is in the population. Hence answer is option A.
Add Answer to:
In density independent populations, birth rate and death rate do not change with population density. In...

Why does the fitness of a phenotype depend on frequency-dependent selection? A. Because selection favors the least common phenotype. B. Because the least number of alleles are at that locus. C. Because sexual selection produces dimorphism. OD. Because frequency-dependent selection acts against extreme phenotypes.

Nitrogen fixation is a key component of biogeochemical cycling. It also represents an important inter-species interaction, which is: A. Commensalism between bacteria and animals B. Competition between plants and fungi C. Predation of bacteria by plants D. Mutualism between plant and bacteria In 1983, a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the...

Death rate > Birth or death rate (per capita) Birth rate - 1 Population Density ove is a figure depicting density-dependent per capita birth and death rates of a single population. hich of the following statements is an ACCURATE conclusion about this population? This population will explode into an inñnite size as density increases. This population will decline to extinction if the population size is too small. This population is regulated by density-dependent negative feedback. This population exhibits exponential growth

In C++ Transient Population Populations are effected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size...
Climate change is a threat to the existence of many species.
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

Terms Definitions Genic selection A form of segregation distortion that occurs during meiosis and causes an allele to have greater than 50% probability of being transmitted to a gamete. Group selection A form of natural selection consisting of nonrandom differences in fitness among different phenotypes (or genotypes) within a population. See...

In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...

In a population of mice a particular locus has two alleles A1 (dominant) and A2 (recessive). There are 126 A1A1, 167 A1A2 and 88 A2A2. Is this population in Hardy-Weinberg equilibrium (3 pts)? In a population of Gragons, there are 3151 A1A1, 1678 A1A2 and 2014 A2A2 individuals. If the environment changes so that the homozygous recessive genotype suffers a reduction of fitness where its fitness is now 0.73, but the other genotypes are unaffected, what will be the frequency...

1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
1b) What is this name...
