We need more information to calculate the frequency of individuals that display the recessive trait (dd) in the mice collected from the Sonoran desert.

To calculate the frequency of individuals that display the recessive trait (dd), we need to know the phenotypic ratio of the mice collected from the Sonoran desert. The information provided in the question does not give the phenotypic ratio for the dark (D) and light (d) phenotypes. Without this ratio, we cannot accurately calculate the frequency of the recessive trait. To answer the question, we need more information.

Answer:

The square of the ratio of the periods equals the cube of the ratio of radii.

Explanation:

German astronomer Johannes Kepler who lived from 1571-1630, gave the three descriptive laws called Kepler's law. He derived this law after he had study and make observations of planetary motion done by Tycho Brahe.

The Kepler's third laws state that the square ratios of the period equals the cube ratio of the distance or radii.

From Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.

Kepler's third law states that the ratio of the square of an object's orbital period with the cube of the semi-major axis of its orbit is the same for all objects orbiting the same primary.

The law is simplified using mathematical formula as follows;

T² ∝ R³

[tex](\frac{T_2}{T_1})^2 = (\frac{R_2}{R_1} )^3[/tex]

where;

Thus, we can conclude that from the Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.

Luisa's Observation.

Explanation:

Luisa's observation is explained better than David's was, and judging by the observations, David studied the same material, while Luisa's observation contained different description, meaning that there was likely more than one substance being observed and studied.

David researched the same material, according to the observations, but Luisa's observation is better explained than David's, and since Luisa's observation had different description, it is possible that more than one item was being viewed and studied.

All occurrences of a random variable are referred to as observations of that variable in statistics. The actual collection of data points is also referred to as a sample of a particular population of observations.

Any value calculated from your sample data is referred to as a sample statistic (or simply a statistic). The sample average, median, sample standard deviation, and percentiles are a few examples.

Because a statistic is based on data gathered through random sampling, which is a random experiment, it is a random variable.

Therefore, Luisa's observations  would prove more useful to a chemist.

Answer:

C. Application of toxic fertilizers to crops

Explanation:

Water pollution is defined as the contamination of water due to several human activities. Several causes of water pollution include use of fertlizers, construction of turbine, industrial waste, and sewage dumping.

Use of toxic fertizers directly affects the loss of water quality as fertilizers and pesticides are made up of chemicals such as phosphate and ammonia. The fertilizers and pesticides precipitate through the soil and mix with ground water that directly affect the quality of water. Residues of chemicals mix with river water due to flooding, excess irrigation, heavy rainfall and enter in the food chain. These chemicals are then have lethal effect in living organisms.

Hence, the correct answer is C.

Answer:

it is "In natural selection, the selection "pressure” comes from the environment; in artificial selection the “pressure” comes from humans."

Explanation:

We know that natural selection is when the weakest basically get sick and killed, and the strongest stay. here is the definition of natural selection: "the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution."

we also know that artificial selection (selective breeding) is when humans take, for example, the juiciest, reddest tomatoes, and breed those to create juicy red tomatoes. the exact definition of artificial selection is: "Selective breeding/artificial selection is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together."

so based on the explanation, we know that natural selection is because of the organisms' environment and that artificial selection is because of humans. I hope this helped you! :]

Final answer:

The primary difference between natural and artificial selection lies in the source of the selection pressure: environmental conditions drive natural selection, while human preferences and interventions guide artificial selection.

Explanation:

The primary difference between natural and artificial selection is where the selection "pressure" comes from. In natural selection, environmental factors such as predators, availability of food, or climate conditions act as the selection pressure, favoring individuals with traits that enhance their survival and reproductive success. Conversely, in artificial selection, humans actively choose which individuals of a species to breed based on desired traits, leading to populations that are more aligned with human preferences over time. Thus, the key distinction lies in natural selection being driven by environmental challenges and survival of the fittest, while artificial selection is guided by human desires and intervention to cultivate certain traits.

Answer:

acid rains that land directly on tress and crops can harm them. which results in more aluminum absorption from soil, which is carried into lakes and streams which can kill the animals in the water

Answer:

Explanation:

Acid rain has many ecological effects, especially on lakes, streams, wetlands, and other aquatic environments. Acid rain makes such waters more acidic, which results in more aluminum absorption from soil, which is carried into lakes and streams. ... Trees' leaves and needles are also harmed by acids.Scientists know that acidic water dissolves the nutrients and helpful minerals in the soil and then washes them away before trees and other plants can use them to grow. At the same time, acid rain causes the release of substances that are toxic to trees and plants, such as aluminum, into the soil.

Many non-native plants are introduced through people dumping their aquariums into bodies of water

People who release non-native animals from captivity (Fish are a big one)

people who bring soil on their boots back from traveling to a different country my introduce non-native bacteria cultures

Answer:

Human travel can lead to an increased risk of invasive species. Native species—both animals and plants—can stow away on cars, trains, boats, and airplanes that bring them to another ecosystem. Climate change also can play a role. Human activity causes increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn creates an increase in global temperatures. Because all species are adapted to a specific climate, climate changes can result in non-native species spreading into other ecosystems.

Answer:D lead

Explanation:

Based on the graph, it appears that the air quality standards have had the greatest impact on lead.

National air quality refers to the level of pollution in the air across an entire nation.

The graph shows a significant decrease in lead concentrations since 1990 when the EPA began regulating lead emissions. The other pollutants, while still showing improvement, do not have as drastic of a decrease as lead.

The graph provided shows the change in concentrations of common air pollutants over time. The pollutant that stands out the most in the graph is PM (particulate matter), as it shows a significant decrease in concentrations over time.

This suggests that the air quality standards set by the EPA have had a positive impact on reducing PM concentrations in the air. Ozone, NO (nitrogen oxide), and lead also show some level of decrease in concentrations over time, but the decrease is not as significant as that seen with PM.

Explanation:

any force can be added to make a stationary object move. but if it was balanced then it would just stay in position

if there is 100N of force going towards the object, and you are pushing the object with 100N force. It  will not move.

Final answer:

The statement that an unbalanced force must act upon a stationary object to set it into motion is true according to Newton's first law of motion. An object at rest remains at rest, while an object in motion maintains its velocity unless acted upon by an unbalanced force.

Explanation:

The statement that an unbalanced force must act upon a stationary object to set it into motion is True. According to Newton's first law of motion, also known as the law of inertia, an object will not change its state of motion (i.e., it will not accelerate) unless an unbalanced force acts upon it. This means that if an object is at rest, it will stay at rest until a force that is greater than the sum of all opposing forces is applied to it. Contrary to misconceptions, a force can do work even if an object doesn't move, for instance if you're pushing against a wall with a force, work is being done on a molecular level, although there's no macroscopic movement.

When two unequal forces act on an object, the object will move in the direction of the net or resultant force, which is the vector sum of all the forces acting upon it. If this net force is zero, the object will remain stationary or continue to move at a constant velocity. This is a fundamental concept in classical mechanics.

Answer:

Option A, accumulation

Explanation:

As we can see in the image,  the water gets heated and convert its pahse from liquid to gas i.e from liquid water to water vapor.  As it rises above, it condenses and converts from water vapor into liquid water. The liquid water then moves in the downward direction and collects at the base. This process of collection at base can be related to accumulation of running water.

Option A is correct

The optimal pH for pepsin is 1.5 and lipase has an optimal pH around 7-8. Lipase is not typically found in the stomach.

The optimal pH for pepsin, the main digestive enzyme in the stomach, is 1.5. Pepsin works best in the acidic environment (low pH) of the stomach, where it helps break down proteins into smaller molecules.

On the other hand, lipase is an enzyme that primarily functions in the small intestine. The optimal pH for lipase is around 7-8, which is considered neutral to slightly alkaline.

No, lipase is not typically found in the stomach. It is primarily produced and secreted by the pancreas, and its main role is to break down fats (lipids) into smaller components that can be easily absorbed and utilized by the body.

https://brainly.com/question/41867465

#SPJ12

Pepsin's optimal pH is 2.0 for protein digestion in the stomach. Lipase's optimal pH is 8.0, active in the small intestine.

The optimal pH for enzymes can vary significantly, and it's important for their activity in different parts of the body:

1. Pepsin is an enzyme that works in the stomach, and its optimal pH is approximately 2.0. This highly acidic environment is conducive to the enzyme's activity in breaking down proteins.

2. Lipase, on the other hand, has an optimal pH of around 8.0, which is more alkaline. This enzyme is not typically found in the stomach. Instead, lipase primarily functions in the pancreas and the small intestine, where it aids in the digestion of fats.

3. Given that the stomach is a highly acidic environment, lipase would not be as active there due to its preference for a more neutral to alkaline pH. Therefore, it's not considered a major enzyme of the stomach. The primary lipase for digestion, pancreatic lipase, operates in the small intestine where the conditions are more suitable for its activity.

Enzymes like pepsin and lipase are crucial for digestion, each working best under specific pH conditions that match their location in the digestive system.
