David and Luisa are trying to determine if two samples are the same or different substances. First, they observed sample 1 and sample 2. Then, they wrote down their observations. Review their observations. Then, answer the questions below.

Which student’s observations would prove more useful to a chemist?

David's observations

Luisa's observations
Explain your answer below.

Answers

Answer:

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.

What is observed sample?

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.

The primary difference natural and artificial selection is:

Question 12 options:

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


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


Natural selection is when humans breed the animal; artificial selection is when humans edit genes directly.

Answers

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.

How does acid rain effects the plants and animals of an ecosystem?

Answers

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.

Water is a substance essential to life and includes rain, groundwater, lakes, ocean etc.

The Water cycle is a cycle which describes the overall movement of water from above the earth to the below the surface of the Earth.

Water cycle includes four steps:

Evaporation/Transpiration: The is when water goes into air because of the heat caused by sunCondensation: This is when water vapor caused by sun forms the cloud. Precipitation: This is when the cloud is too heavy for the air to carry and then falls back to the earth. Storage/Collection: This is when the water which falls back is stored or collected such as lakes, groundwater, rivers etc

In conclusion, the cycle of water moves from the fourth step to the first step and continues like that infinitely, thus, the amount of water on Earth stay the same

As the Earth rotates on its axis and revolves around the Sun, the Earth goes through seasonal changes. Why does this happen?
A. because the Moon revolves around the Earth
B. because the Earth's axis is tilted
C. because the Earth rotates slowly
D. because the Earth is closer to the Sun during the summer

Answers

Answer: The answer is B: Because the earth's axis is tilted.

Explanation:

Instead, Earth has seasons because our planet's axis of rotation is tilted at an angle of 23.5 degrees. The tilt in the axis of the Earth is called its obliquity.

As the Earth rotates on its axis and revolves around the Sun, the Earth goes through seasonal changes. Because the Earth's axis is tilted.

What is Earth's axis?

The Earth's axis is inclined 23.4 degrees, or almost halfway between its extremes, and this angle is steadily getting smaller throughout the course of a cycle that lasts roughly 41,000 years.

It was last tilted to its highest position approximately 10,700 years ago, and it will tilt to its lowest position in roughly 9,800 years. As obliquity gets less, it gradually helps to milden our seasons, producing warmer winters and cooler summers that eventually allow snow and ice to accumulate into massive ice sheets at high latitudes.

As the amount of ice cover grows, more of the Sun's radiation is reflected back into space, causing a further cooling.

Therefore, As the Earth rotates on its axis and revolves around the Sun, the Earth goes through seasonal changes. Because the Earth's axis is tilted.

The type of population growth that most natural populations follow is

Answers

Answer:

The type of population growth that most natural populations follow is Exponential growth.

hope it helps!

Final answer:

Natural populations often follow logistic growth, which includes an initial rapid growth phase followed by a slowdown as carrying capacity is approached. The growth pattern forms an S-shaped curve, commonly seen in species such as the snowshoe hare.

Explanation:

Most natural populations follow logistic growth. Unlike exponential growth that continues indefinitely, logistic growth takes into account environmental resources and carries capacity. In a logistic growth model, the population increases rapidly at first, but as it nears its carrying capacity - the maximum population size that an environment can support - the rate of growth slows down and eventually stabilizes.

A classic example of a species that follows logistic growth is the snowshoe hare. Initially, the population will grow rapidly, until resources such as food start to become scarce. As a result, the population's growth rate will slow down and eventually stabilize, demonstrating an S-shaped curve indicative of logistic growth.

1. what is the optimal pH for pepsin ?

2. What is the optimal pH for lipase?

3. Do you think lipase is an enzyme that is found in the stomach ?

Answers

Final answer:

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.

Explanation:

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.

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.

From the term 'fossil fuels', we can deduce that these energy sources are formed from ancient biological matter and b) have been buried in the earth's crust for millions of years.

From the name fossil fuels, we can infer that they are derived from b) biological materials that were fossilized over millions of years. The term fossil indicates that these fuels come from ancient organic matter buried and compressed in the earth's crust, typically from prehistoric plants and animals. When they are burned, they release energy stored from the Sun by these ancient organisms in the form of hydrocarbons. Therefore, the most accurate inference from the name would be that fossil fuels have been buried in the earth's crust for millions of years.
