Where are most of the nutrients from food absorbed? And what happens to the nutrients once they’re absorbed? (Worth 20 points)
Answer:
Nutrients get absorbed as the food is broken down, with the majority of nutrients being absorbed in the small intestine, where they're then transported into the blood stream
Explanation:
The majority of nutrients from food are absorbed in the small intestine after digestion. Nutrients enter the bloodstream or lymph system and are transported throughout the body. Undigested and unabsorbed materials are passed to the colon for water reabsorption and waste elimination.
Most of the nutrients from food are absorbed in the small intestine. The digestive system begins breaking down food in the mouth where enzymes in saliva start the process of digestion. This process continues as food moves to the stomach and then to the small intestine, where enzymes complete the digestion of food.
Once digestion is complete, the absorption of nutrients takes place. This is where substances pass into the bloodstream or lymph system, allowing them to circulate throughout the body. A substantial percentage, approximately 95%, of nutrient molecules are absorbed in the jejunum, the second part of the small intestine.
Other nutrients, such as iron and vitamin B12, are absorbed in different parts of the small intestine like the duodenum and ileum, respectively. Post-absorption, nutrient molecules are transported to various parts of the body for storage or further chemical modification.
Any undigested and unabsorbed matter moves into the colon (large intestine), where water is reabsorbed and the remaining waste material is eventually eliminated from the body through defecation.

C.
smallpox
D.
tuberculosis
Please select the best answer from the choices provided.
A
B
C
D
Final answer:
Smallpox is the correct answer as it is not an endemic disease; it has been eradicated worldwide. Malaria, typhoid, and tuberculosis remain common endemic diseases in specific geographic areas.
Explanation:
All of the following are common endemic diseases, except smallpox. The correct answer is C. Smallpox.
Endemic diseases are those that are constantly present in a population within a particular geographic area. Malaria (A), typhoid (B), and tuberculosis (D) are all examples of endemic diseases. Malaria is often found in tropical climates and is transmitted by mosquitoes. Typhoid is a waterborne illness that remains a significant concern in areas with poor sanitation. Tuberculosis is a respiratory infection that is quite common in many parts of the world, particularly in urban areas with dense populations.
However, smallpox has been eradicated worldwide due to an effective global vaccination campaign. The last known natural case was in 1977, and it is no longer commonly found anywhere in the world, making smallpox the correct choice for the disease that is not endemic.
12. If orange flower color in a plant is controlled by an allele F and red flower color is controlled
by an allele fwhich flower color is dominant?
Answer:
orange
Explanation:
The dominant flower color in this scenario is orange as it is represented by allele F. In genetics, uppercase letters denote dominant traits, while lowercase letters denote recessive traits.
Explanation:In genetics, dominant alleles are those which express their effect even if there is only one copy of the gene in the organism's genotype. According to the question, orange flower color is controlled by allele F and red by allele f. Generally, uppercase letters like F are used to denote dominant traits whereas lowercase letters like f are used to denote recessive traits.

Which consequence of pollution is shown in the photograph?
A. Pollutants react with water and are deposited on Earth’s surface.
B. Eutrophication occurs in the presence of too many nutrients.
C. Pollutants break down the layer of ozone in the stratosphere.
D. Gaseous pollutants and particulate pollution form a haze over cities.
The consequence of pollution shown in the photograph is option D: Gaseous pollutants and particulate pollution form a haze over cities.
The photograph visually represents the presence of pollution in the form of a haze that hangs over urban areas. This haze is often caused by the emission of gaseous pollutants and particulate matter from various sources such as vehicles, factories, and power plants.
It is a visible manifestation of air pollution and can have detrimental effects on air quality, human health, and the environment.
The photograph shows that, due to pollution, gaseous pollutants and atmospheric pollution form fog over cities, as shown in option D.
What is the impact of this?
Lower incidence of solar rivers.Impairment of gas exchange.Increased respiratory problems.Extreme pollution causes polluting particles, less dense than air, to rise to the surface and combine with gaseous pollutant emissions, many from the burning of fossil fuels, remaining above the horizon, reducing visibility, and causing gas traps. inefficient, increasing the heat level and causing many respiratory problems.
In addition to temperature, what other factor is taken into consideration to classify
climatic regions?
A: distance from bodies of water
B: altitude
C: precipitation
D: Ocean Currents
precipitation Explanation:
Final answer:
Precipitation (option C) is another factor considered when classifying climatic regions, and together with temperature, greatly influences the type of biome present. Elevation, latitude, wind systems, ocean currents, and proximity to water bodies are critical in shaping climate and biomes.
Explanation:
In addition to temperature, option C: precipitation is another factor taken into consideration to classify climatic regions. Precipitation, alongside temperature, is one of the two variables that most strongly contribute to the type of biome that exists in a particular area. Other factors that influence temperature, precipitation, and the distribution of climate regions include elevation, latitude, wind systems, ocean currents, position on a continent, and mountain barriers. These elements are integral in determining the climate and subsequently the biomes present in different regions. For example, elevation affects climate as temperatures generally decrease with increased altitude, leading to varied biomes along a mountain range.
Furthermore, the proximity to large water bodies also significantly influences climate by providing a temperature moderating effect. Ocean currents can affect temperature and seasonal weather events, such as the North Atlantic Current which brings warm water to the north, or the California Current which brings cooler water to the south. Geography, therefore, is complex and interconnected, with various physical and human factors shaping the classification of climatic regions and the distribution of ecosystems within them.

A computer simulation showing models of planes crashing is a good way to study the effects of plane safety.why?
Answer:
Flight simulators are widely used for pilot training in the aviation industry, military pilot training, simulation of disasters or failures in flight, and aircraft development.
These simulations are used for pilot training, whose essential function is to train the crew in normal, abnormal and emergency procedures, before and during flight, practicing innumerable situations, such as: failures in electronic systems, loss of power, tailwinds and many others, which cannot be done safely with an aircraft in real situations. Explains to the new pilots the movements and attitudes of the ships, becoming a fundamental part of the training, saving lives and large economic losses.
These simulations allow knowing the causes of each plane crash in order to modify the operating procedures and training, so that its repetition is avoided. Flight safety investigations are complex and analyze numerous factors, and rather than investigating the persons responsible, it tries to find out the causes of the incident, considering human factors and technical issues.

As you work through the lab, be sure to complete the Heredity Lab Report. You will submit your completed lab report for grading. Review the grading rubric before you begin.
Answer:
Hamster interit their traits based on their parents genes.
Explanation:
Hamsters do inherit their traits for long fur or short fur through the parents. The parents are what affects the offspring's traits, these are determined by the different genes. For example, if there is a recessive gene for short fur, then there will be less of a chance for the offspring to inherit short fur and vice versa. In some instances, there is a recessive gene and a dominant gene, in that case, the dominant gene will overpower the recessive gene hence it's name. There are three types of possible gene pairs, homozygous dominant: AA, homozygous recessive aa, and heterozygous dominant, Aa.If there is two of the recessive genes, then there is a higher chance for the short fur to appear in the offspring and etc.

secondary succession?
a. Forest fire
b. Flood
c. Logging
d. Volcanic eruption in the ocean
Answer:
D.
Explanation:
Secondary succession occurs in an area that has already been inhabited. If a new island forms from the volcanic eruption, new species may move in and start a new ecosystem there.
Secondary succession occurs in areas where an established ecosystem has been disrupted. This disruption can be caused by a forest fire, flood, or logging. However, a volcanic eruption in the ocean, which creates an entirely new biosphere, would result in primary succession.
Explanation:The question is asking which of the listed events would not lead to secondary succession. Secondary succession is a form of ecological succession that occurs in areas where an ecosystem was previously established but got disrupted. This disruption can be caused by several things, such as fires, floods, or human activities like logging.
Examples of secondary succession include a forest being regrown after a forest fire, or plant life returning to an area that has been logged. However, a volcanic eruption in the ocean would result in primary succession, not secondary. This is because primary succession occurs in a new habitat where no life existed before. In this case, plants and animals must begin life anew, starting from bare rock or ash, unlike secondary succession where there is already soil and often seeds waiting to germinate.
