Which best describes tA male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? he fossil record?
Question:
A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?
Answer:
Feather color loses importance in sexual selection and becomes disadvantageous for males. There is a decrease in red color variation among males.
Explanation:
In cardinal species, females choose males to mate according to their vibrant red color. The redder the male is, the better genetic charge it has, and the better choice for mating it becomes.
Red feather color is a trait that reflects the genetic quality of males. So individuals with the most vibrant red color express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.
The brightest or most vibrant males are in red, the better chances they have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors to enhance mating chances.
However, if females begin using different criteria than feather color when they choose mates, color production stops making sense. What is even more, it becomes more disadvantageous for males because females do not use color for their choices, males spend energy when producing it, and the redder the males are, the more chances to be predated they have. So basically, males´ feather color loses importance. The selection pressure in males turns to the evolution of another trait. The shade variation of red feathers will decrease over time.

Explanation:
Moving a book to a lower shelf decreases potential energy.
True
False
Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

Why are there many, many more craters on the "outer back" side of the moon than there are on the "inner facing" side of the moon?
Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.
Explanation:
The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.

Termites are unable to digest some plant materials (fiber). Termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
commensalism
mutualism
parasitism
competition
The relationship between the termite and bacteria is called mutualism.
What is mutualism?Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.
According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.
This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.
Learn more about mutualism at: https://brainly.com/question/2357375
The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.
What is Mutualism?A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.
A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.
Therefore, the correct option is B.

A high population of greater prairie chickens once inhabited the prairies of Illinois. The conversion of the prairies into agricultural land caused the chickens to lose their habitat. Studies have concluded that this change greatly reduced the greater prairie chicken population. The habitat loss also resulted in a decrease in the population’s genetic variation.
Which change in the gene pool occurred in the greater prairie chicken population?
gene mutation
gene flow

Which of the following are pieces of evidence showing common ancestry among species?
Answer:
1. The pieces of evidence that support the theory of evolution include the following:
a. Fossil records/evidence
b. DNA of the organisms
c. Comparative anatomy
2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.
3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.
In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Answer:
Photosynthesis and cellular respiration allow the carbon and oxygen that organisms consume and produce to be cycled through the ecosystem. They work together so that what is made from one process is used in the other. Without them the ecosystem would run out of carbon dioxide and oxygen, and everything would die.
