Answer 1

Answer:

Looks hard

Explanation:

I dont know how to do this

Answer 2

Actual width of the cholera bacterium between points X and Y is: 6.5 mm × (1,000 um/1 mm) = 6,500 um.

What is cholera bacterium?

The cholera bacterium is a single-celled, rod-shaped bacterium called Vibrio cholerae. It is a type of bacteria that can cause severe diarrhea and dehydration if ingested through contaminated water or food.

The actual width of the cholera bacterium between points X and Y can be calculated as follows:

Width of the bacterium on the diagram = 0.06 cm

Magnification = 50,000 times

Actual width of the bacterium = (width on the diagram) / magnification

= (0.06 cm) / (50,000)

= 0.0000012 cm = 0.012 µm (micrometers)

Thus, the structure C is flagellum and its function is to provide locomotion.

Part B Which shape of molecules do scientists think may be important for the development of life and why?

Answers

Answer:

Molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. The Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.

Answers

Answer:

Fiber

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.

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.

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.

The ozone layer is an important component of the atmosphere that protects life on Earth from harmful ultraviolet radiation from the sun, and one of the major threats to the ozone layer is the release of man-made chemicals such as CFCs, which can react with ozone and deplete it, so if the ozone layer is depleted, more ultraviolet radiation can reach the Earth's surface, causing skin cancer, cataracts, and crop damage.

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.

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.
