Complete question:
A population of bats feeds on flying insects. Some of these bats have a gene that results in much stronger flight muscles than those of the other bats in the area. Explain how this variation could lead to evolutionary change within this species of bat. In your answer, be sure to include an explanation of
Competition within the bat populationSurvival of various individuals within the bat populationHow the frequency of the trait for stronger flight muscles would be expected to change within the bat population over time.Answer:
Animals with the gene of stronger muscles are better competitors, which means more chances to survive and to reproduce. When they reproduce they pass the gene to the progeny, increasing the allele frequency in the population, probably until fixating it.
Explanation:
Within a population occurs competition among individuals for different resources such a food, territory, refuge, access to females, among others. Feeding habits result in a very important factor that models the species structures, and that might even result in the differentiation of the species into subspecies. Competition for food acts as pressure for animals leading them to develop new strategies for food access. In the exposed example, one of these new strategies is related to a better flight, which is possible due to the gene that results in much stronger flight muscles. Individuals that develop stronger flight muscles are more competitive and probably improve their social status, not only because they can get access to more and better food, but also because this means a better genetic charge which makes them better for mating. These animals have more chances to survive and reproduce: they are stronger and they feed better than the other individuals. The stronger flight muscles are not only useful for feeding, but also for avoiding predators, and for competition. Animals with this gene probably live longer.
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. The mutation in the gene of muscle development turns to be beneficial for the species. Animals that carry the gene have more chances to mate and reproduce, and hence to pass the gene to the progeny. In this way, the allelic frequency will increase within the bat population over time.
The study of an environment is called ecology.
The difference in the genes in the given population is called variation and this variation leads to the formation of a new character that has a higher chance of surviving in nature.
These variants have the tendency to choose naturally for the environmental condition.
According to the question, if the bats have the stronger muscle to fly they will reach the prey easily and eat them, before the slow-flying.
This leads to increase competition and the inferior species will extinct due to the higher rate of competition.
Hence, the fast-flying bats are selected naturally and inferior species will extinct.

freckles (but her mom does not) but no dimples.
1. What is the probability that these parents will have a child with dimples?
2. What is the probability that these parents will have a child with freckles?
3. What is the probability that these parents will have a child with dimples and freckles?
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb

What is one event that may occur during Telophase I?
An event that may occur during Telophase I is: the nucleus of each cell may reappear as two independent cells are being formed.
Meiosis can be defined as a type of cell division or duplication that occurs in all body cells found in living organisms, through which a single cell divides twice to produce four (4) haploid cells (gamete).
Basically, deoxyribonucleic acid (DNA) must replicate before meiosis can occur in all body cells found in living organisms.
Generally, the phases or steps that occur during meiosis include:
Prophase I.Metaphase I.Anaphase I.Telophase I.Prophase II.Metaphase II.Anaphase II.Telophase II.Sometimes, the nucleus of a single cell may reappear when two (2) independent cells are being formed during Telophase I.

Scientists recently studied the reproductive behavior of a yeast species. They noticed a new species emerged from two populations. This new species formed after the yeast were exposed to signaling molecules called pheromones. Both male and females release pheromones, which bind to cell surface receptors. Pheromones from the male bind to female cells. The opposite is true for pheromones secreted from female cells. This signaling action causes the yeast to change their sex type.
Explain how this phenotypic plasticity is beneficial.
Answer:
Phenotypic plasticity in yeast cells is beneficial because this allows the yeast to change its phenotype of being a male or female. This plasticity depends on the type of pheromone exposure. The ability to change phenotype increases the reproductive success of yeast cells. This condition is useful for yeast, especially if they must adapt to changes affecting their reproduction and survival. By having phenotypic plasticity, the yeast can continue to grow its population size.
Answer:
When the yeast is exposed to a pheromone, its phenotypic plasticity allows it to change its sex type, meaning if there is a yeast molecule that is releasing pheromones close to another molecule of yeast, the latter molecule will change its sex type to the opposite sex, if necessary, to reproduce. The yeast's phenotypic plasticity regarding sex type allows it to grow the population more effectively, helping the species survive.

Explanation:
Write a short paragraph that explains the relationship between the terms "chromosome," "gene," "DNA," and "allele."
Answer: Genes appear throughout the length of each chromosome, and each chromosome pair has a unique set of genes. ... In a diploid organism, the two corresponding genes in a chromosome pair, or alleles, might be identical or might have different base sequences. Each parent contributes one allele in each pair.Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !

Which disappears more rapidly from a population, a deleterious dominant allele or a deleterious recessive allele?
Answer:
Selection is a directional process that leads to an increase or a decrease in the frequency of genes or genotypes. Selection is the process that increases the frequencies of plant resistance alleles in natural ecosystems through coevolution, and it is the process that increases the frequencies of virulence alleles in agricultural ecosystems during boom and bust cycles.
Selection occurs in response to a specific environmental factor. It is a central topic of population and evolutionary biology. The consequence of natural selection on the genetic structure and evolution of organisms is complicated. Natural selection can decrease the genetic variation in populations of organisms by selecting for or against a specific gene or gene combination (leading to directional selection). It can increase the genetic variation in populations by selecting for or against several genes or gene combinations (leading to disruptive selection or balancing selection). Natural selection might lead to speciation through the accumulation of adaptive genetic differences among reproductively isolated populations. Selection can also prevent speciation by homogenizing the population genetic structure across all locations.
Selection in plant pathology is mainly considered in the framework of gene-for-gene coevolution. Plant pathologists often think in terms of Van der Plank and his concept of "stabilizing selection" that would operate against pathogen strains with unnecessary virulence. As we will see shortly, Van der Plank used the wrong term, as he was actually referring to directional selection against unneeded virulence alleles.
A deleterious dominant allele would disappear more slowly from a population compared to a deleterious recessive allele.
What is a deleterious dominant allele?In the case of a deleterious dominant allele, the individual possessing the allele will always express the negative trait associated with it, making it easier to identify and potentially select against. In contrast, a deleterious recessive allele may not be expressed in individuals who carry only one copy of the allele, as the normal copy of the gene can still produce enough functional protein to mask the effects of the deleterious allele.
As a result, the deleterious recessive allele can persist in a population as carriers pass the allele on to their offspring without showing any negative effects themselves. However, over time, the recessive allele may become more common in the population, increasing the likelihood of two carriers mating and producing offspring that express the deleterious trait.

The appearance of the moon changes in a predictable pattern that lasts approximately 28 days.the changes in appearance are called phases of the moon.what is the main cause of the moon phase
Answer:
The main cause of the moon phases is the changing position of the moon in relation to the sun and the earth.
Explanation:
The moon phases are the perception of the part of the moon that is visible, when observed from the earth. When it is completely visible it is called full moon, when it cannot be seen it is called new moon and the phases between one and the other are called crescent and waning quarters.
The moon can be visible when it receives illumination from the sun but, due to its changes in position with respect to the earth, this illumination can be complete, partial or absent, which defines each of the phases.
When the moon completes its four phases it is called the lunar cycle, and it has an estimated duration of 29.5 days.
