A research study looked at variations in snail populations in urban areas compared to natural ecosystems outside of the urban development. Urban areas tend to be be warmer, trapping more solar energy and reflecting less light back out of the atmosphere. The study found that brown snails were more commonly found in the natural ecosystem while yellow banded snails were found in the urban, developed areas. Which statement best describes the distribution in the phenotypes for the snails in this scenario?
A) The variations in the snail populations are random and unrelated to the locations.
B) The variation in the snail population is due to sexual reproduction of the snails in the urban development and asexual reproduction of the snails in the natural ecosystem.
C) The variation in the snail population is due to mutations while the distribution of colors in the population is due to genetic drift. The location of the colors is a random process.
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Answer:
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Explanation:
The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or manifestation of desired characters. Phenotypes may also be known as traits.
The phenotypes of snail may get changes due to mutation which is caused by the high temperature in an urban area. UV light is considered a physical agent of mutation. Hence, the variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter-colored snails survive with greater frequency in the warmer urban development.
Therefore, The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.

PLEASE MARK ME AS BRAINLIESTWILL GIVE BRAINLISTTT!!! How can life and conditions on Earth be used as a model for life on other worlds?
Answer:
You can see the conditions of the other world, and see the composition of that world. This allows you to see what elements are abundant. Assuming there is water on that other planet, you can use the elements that are found there and see what organisms on earth are composed of those elements or use them.
Specifically, extremophiles (types of archaeabacteria) often exhibit characteristics that seem suitable for other planets. Using this, you can estimate what life on other planets have as characteristics, or even what they are made of.
Organisms with similar molecular makeups + organisms in areas with similar environmental pressures often exhibit anatomical + behavioral similarity. You can use this to model this.

3. How are frog eyes different from human eyes?
Answer:
Most frogs see well only at a distance, but they have excellent night vision and are very sensitive to movement.This peripheral vision helps them spot predators and prey. Humans and other mammals focus images by changing the shape of the lens. Like a camera lens, frog eyes focus by moving the lens back and forth.

Describe the weather conditions for a Warm front.
Answer:
Explanation:
Warm fronts bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable.

Overfishing is a global problem in which humans harvest certain species of fish, almost to the point of extinction. Many of the fish stocks depleted by overfishing are at the top of the food chain. Why would the overfishing of very large fish cause a decrease in the numbers of small fish?
The small fish are more likely to die from diseases and parasites.
The small fish live in a mutualistic relationship with the large fish.
The small fish have a greater number of medium-sized predators.
The small fish must compete with each other for fewer food sources.

How do hypothalamus and pituitary glands work together?
Answer:
The hypothalamus is responsible for maintaining the body's internal balance (homeostasis) by stimulating or inhibiting major bodily functions such as the heart rate and blood pressure, body temperature, fluid and electrolyte balance, appetite and body weight, sleep cycle and function of the gastrointestinal track. The hypothalamus is also considered the master regulator of the endocrine system; Regulatory hormones secreted by the hypothalamus are transported by the hypophyseal-portal system to the anterior and posterior pituitary, prompting the release of secondary hormones that can affect various organ functions.

Answer:
First, describe each type of evidence (eg. Molecular biology is comparing DNA sequences to determine common ancestry). Then provide examples of how those pieces of evidence support the theory of evolution. For example, for one of the comparative anatomy examples, you could say that organisms that contain similar structures most likely diverged from a common ancestor.

How are the acceleration, the net force, and the mass of an object
related?
Answer:
Newton’s second law details the relationship between net force, the mass, and the acceleration: The acceleration of an object is in the direction of the net force. The acceleration has a magnitude directly proportional to the magnitude of the net force. The magnitude of the acceleration is inversely proportional to the mass of the object.
