Answer:
A. Selective pressure in the form of a new predator
Explanation:
A. Selective pressure in the form of a new predator
A. Selective pressure in the form of a new predator is the most likely factor that caused the noncroaking male population to increase after 2004.
What is noncroaking males?Noncroaking males refer to male bullfrogs that do not produce croaking sounds as a form of communication or mating behavior.
The migration of a bat species that preyed on male frogs likely created a selective pressure on the population, favoring those males that did not croak and thereby avoiding detection by the predator. This would result in a higher proportion of noncroaking males in the population over time as they have a higher likelihood of survival and reproduction.
The increase in the noncroaking male population after the arrival of the bat predator in 2005 could be due to adaptation of the male frogs to the new selective pressure in the form of the predator.
It is possible that the noncroaking males were able to avoid detection by the bat predator better than the croaking males, leading to a higher survival rate and ultimately a higher population.
Additionally, it is possible that the croaking males were more likely to be predated upon, leading to a decrease in their population and an increase in the noncroaking male population.
However, it is also possible that other factors, such as changes in the environment or competition with other species, could have contributed to the observed changes in the bullfrog population over time.

On the planet Greenport, individuals display two distinct phenotypes: their favorite color s blue versus their favorite color is green. Every Greenportian has one of these two phenotypes. Suppose the phenotypes are determined by genotypes on two loci. The first locus, Quogue, has alleles F and f. The second locus, Massapequa, has alleles G and g. These loci act in an epistatic manner to produce the favorite-color phenotypes. A cross between two doubly heterozygous individuals, that is, each with the two-locus genotype FfGg, produces 1100 offspring whose favorite color is blue, and 875 offspring whose favorite color is green. What form of epistasis is most consistent with these counts
Answer:
double recessive epistasis.

If a fresh cucumber slice is placed in very salty water, which direction will the water move, into the cells of the cucumber or out of the cucumber?
If we sprinkle salt on cucumber slices, it releases water after some time due to the process of osmosis. Osmosis is a process where solute or salt from higher concentration moves towards lower concentration through a semi-permeable membrane. Here, in this case, the salt concentration is more outside on the cucumber slices. The individual cell membrane of cells present in cucumber slices acts as a semi-permeable membrane. Inside the cucumber cells, there is less concentration of salt or solute and more concentration of water. Therefore, the salt from outside goes inside individual cells and the water comes out as it also travels from higher concentration to outside lower concentration through a semi-permeable membrane.

Using the Punnett Square for the Rr x Rr cross, what percentage of the offspring are going to be heterozygous?
100%
50%
0%
75%
Answer:
50%
Explanation:
The punnet square gives you a 25 percent probability of RR, a 50 percent probability for Rr, and a 25 percent probability for rr. Rr is the only option heterozygous
Using the Punnett Square for the Rr x Rr cross, 50% of the offspring are going to be heterozygous. Thus, the correct option is Option B.
What is a Punnett Square?The Punnett square is a square diagram used to predict genotypes of a specific cross or breeding experiment. It is named after Reginald C. Punnett, who invented it in 1905. Biologists use the diagram to calculate the likelihood of an offspring having a specific genotype.
The Punnett square is a table that lists all possible combinations of maternal and paternal alleles. These tables can be used to investigate the genotypical outcomes of offspring of a single trait (allele) or when crossing multiple traits from the parents. The Punnett square represents Mendelian inheritance visually.
Therefore, 50% of the of the offspring are going to be heterozygous or the Rr x Rr cross, using the Punnett Square.

Often the growth cycle of one population has an effect on the cycle of another. As moose populations increase, for example, wolf populations also increase, which will then reduce the moose population. Thus, if we are considering the logistic equation for the wolf population, which of the factors accounts for the effect of wolves on the moose population
Answer:
K (carrying capacity)
Explanation:
In logistic growth, the population growth decreases as population size approaches its maximum value, i.e., when the carrying capacity of the environment is reached. In consequence, the carrying capacity can be defined as the maximum population size in a particular environment, which depends on a given resource (e.g., food, habitat, water, etc).
The logistic equation for logistic growth is: dN/dt = rN [K - N/K] >>
dN/dt = change in population size in a given time interval
N = population size
r = intrinsic rate of increase
K = carrying capacity

What are volcanoes?A volcano has a hill or mountain or it has an opening in a planet or moon's crust from which molten rock, warm gases, and materials erupt. It has a landform where molten rocks erupt through the surface of the planet and volcano moutains open downwards to molten rocks.
According to Geologists there's are four types of the volcanoes and these are lava domes, shield volcanoes, composite volcanoes, and cinder cones.
The main reason behind the formation of volcanoes are movement of tectonic plates it means when one tectonic plate moves under another tectonic plate volcano has formed.

2. Different beaks variations did Charles Darwin observe after studying the Galapagos finches.
What are Galapagos Islands known for?The Galápagos are best known for their diverse of plant and animal species. Many species are endemic, that means they are not found anywhere else in the world.
3. Darwin used theory as he gave that survival of the fittest and other will die and evolution to explain these adaptations. The birds on different islands adapted to varying, but specific food types.
4. Darwin’s on the origin of Species, four factors affect evolution are
mutation: a mutation is a change in the DNA sequence of an organism. gene flow: is the introduction of genetic material from one population of a species to another, that leads to change in the composition of the gene pool of the receiving population.genetic drift: is a mechanism of evolution featured by random fluctuations in the frequency of a specific version of a gene (allele) in a population.natural selection: is the process by which populations of living organisms adapt and change.5. Daphne Major was the ideal place to study the evolution of the finches because the finches have few predators / competition for food on that island.

Name 2 ways wind energy is used to move objects.
Name 2 ways water energy is used to move objects.
Answer:
Wind - Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity. ... The difference in air pressure across the two sides of the blade creates both lift and drag. The force of the lift is stronger than the drag and this causes the rotor to spin.
Water - The energy from moving water can be used to create electricity in several different ways. For example: A hydroelectric dam captures energy from the movement of a river. Dam operators control the flow of water and the amount of electricity produced
