The application of evolutionary principles to the study of human variation Group of answer choices allowed scientists to divide the human species precisely into well-defined races helped replace earlier views based solely on observed phenotypes; brings the focus to geographic ancestry reinforced traditional views of races as fixed biological entities that do not change supports the idea that ethnicity and race are categories that can be used interchangeably (they are the same thing) when describing groups of modern humans.

Answers

Answer:

helped replace earlier views based solely on observed phenotypes

Explanation:

The study of human variation has shown that individuals from different populations (previously erroneously considered as geographic races) are often genetically more similar than individuals from the same population. In consequence, the evolutionary approach for understanding human variation has enabled us to discard the biological race concept based solely on observed phenotypes in order to provide a more realistic variation concept associated with evolutionary human development. From this perspective, it has been possible to confirm that 1-there are no human subspecies and 2- the concept of human races is not scientifically suitable to describe human variation.

How can scientists use the fossil record to find evidence of relationships between different species?

Answers

Answer:

Species can be classified using the fossil record based on analogous or homologous structures.

Explanation:

By comparing the anatomy of both modern and extinct species, paleontologists can infer the lineage of those species, scientists use the fossil record.

What is Fossil?

A fossil is defined as the preserved remains, imprint or trace of a once living thing from a past geological age. Some examples of fossils are bones, shells, exoskeletons, stone marks of animals or microbes, objects preserved in amber, hair, petrified wood, and DNA residues. The totality of fossils is known as the fossil record.

Fossils form the morphological, or anatomical record, through comparing the anatomy of both modern and extinct species with the comparative anatomy of present-day organisms, paleontologists can infer the lineage of those species.

Thus, by comparing the anatomy of both modern and extinct species, paleontologists can infer the lineage of those species, scientists use the fossil record.

What part of the body is not working as it should when you have asthma

Answers

Answer:

The Lungs

Explanation:

Asthma is a lung disease that affects your airways. With asthma, the lining of your airways is constantly hypersensitive, resulting in redness and swelling (inflammation). It's similar to how sunburned skin turns red, irritated, and sensitive. The airways become hypersensitive to things you are exposed to on a daily basis, or asthma "triggers." a trigger could be a common cold, stress, changes in the weather, or environmental factors like dust, chemicals, smoke, or pet dander.

Airway remodeling can occur as a result of poor asthma management. When asthma is untreated or poorly managed, it can lead to airway remodeling, which is a serious condition. The lungs become scarred, asthma medications become less effective, and less air can pass through your airways. It is not necessary to remodel the airways.

In addition to oxygen gas, for the fermentation the basic substrate such as sugar is required. Some yeasts are required that can ferment sugars to alcohol and carbon dioxide in the absence of air.

What is Fermentation?

Fermentation is the process in which a substance is broken down into a simpler substance. Fermentation is the metabolic process through which organic molecules such as carbohydrates, such as starch or a sugar are converted into acids, gases, or different types of alcohols in the absence of oxygen or any other type of electron transport chain.

Yeasts are the organisms which preferentially metabolize sugars that are converted principally to ethanol molecule and carbon dioxide gas, however they can utilize different carbon sources, such as amino acids, organic acids, polyols, alcohols, fatty acids, and other organic compounds, depending on the species which undergo metabolic reaction.

A student set up an experiment to show that carbon dioxide is consumed by Elodea plants during photosynthesis. She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes. She added a drop of phenol red which is a pH indicator to both tubes. She blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. She exposed both tubes to the light and recorded any color changes in the liquid in the tubes. What is the negative control in this experiment

Answers

Answer: The NEGATIVE CONTROl is the test tube that is filled with ONLY distilled water.

Explanation:

A negative control of an experiment is carried out alongside the main primary experiment except that the treatment is changed to something that is predicted to have no result. In the negative control, the student does not expect any response. This would help the student compare the result of a new experiment against an already known existing results.

Analysing the experiment carried out by the student, She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes, leaving the other without a plant. The other test tube that contains only distilled water is the negative control because she wasn't expecting any result from it. It's also served as a control sample to the primary experiment. This is observed as she blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. This would help the student know that the that experimental results are valid and to ensure that time is saved.

Explanation:

Fiber is one kind of carbohydrate which is indigestible by the body. Fiber is a part of plant foods which is not digestible for our body.

Fiber is the food component that is indigestible by the body. Therefore, option (B) is correct.


What is a Fiber?

Fiber is a type of carbohydrate found in plant-based foods that the human body cannot digest or absorb. It passes through the digestive system relatively intact and provides several health benefits. There are two types of dietary fiber: soluble and insoluble.

Soluble fiber dissolves in water to form a gel-like substance in the digestive system, which can help lower cholesterol levels, regulate blood sugar, and promote feelings of fullness. Examples of foods that are high in soluble fiber include oat bran, beans, apples, and citrus fruits.

Insoluble fiber, on the other hand, does not dissolve in water and helps to add bulk to stool, promoting regular bowel movements and preventing constipation. It also helps to keep the digestive system healthy by feeding beneficial gut bacteria. Examples of foods that are high in insoluble fiber include whole grains, nuts, seeds, and dark leafy greens.

Including a variety of high-fiber foods in the diet can have numerous health benefits, including improved digestion, lowered risk of heart disease, and better weight management.

In 2011 and 2012, scientists working on the Banana River in Florida recorded a dramatic increase in the number of manatee deaths. Over the past 50 years, this area has also seen the human population increase by more than 500,000 people. It is believed that pollution from numerous sewage tanks leaked into the water, eliminating the manatees' food source, replacing it with an alga that is toxic to the manatee. This is an example of A) a natural cycle in an ecosystem B) the effect of increased biodiversity on an ecosystem C) human actions altering ecosystems with serious consequences D) direct harvesting in an ecosystem

Answers

Answer:

C) human actions altering ecosystems with serious consequences

Explanation:

The increase in the manatee´s death during 2011-2012 might be directly related to human actions.

The increase in the number of people during the last 50 years to more than 500,000 individuals, and probably the lack of policies and regulation, lead to an enhance in water pollution by sewage tank leaks.

Pollution probably caused a gradual decrease in the manatee´s principal source of food, which also caused an increase in the toxic algae population.

Algae caused the death of manatees as a consequence of human action that altered the natural ecosystem by polluting water.
