Final answer:
The final event in the process of bacteria becoming resistant to antibiotics is that the antibiotic-resistant organisms survive and reproduce, increasing their proportion in the population.
Explanation:
The process by which bacteria have evolved to resist antibiotics can be summarized by a series of events. First, a mutation occurs in some bacteria that allows them to survive the presence of antibiotic drugs. These antibiotic-resistant bacteria have a survival advantage when antibiotics are used because the drug kills non-resistant bacteria. The final event in this process is that these resistant organisms survive and reproduce, leading to an increase in the proportion of resistant bacteria within the population. Over time, this can result in a population of bacteria that are all resistant to the antibiotic that was used.

Explanation:
Inert elements are elements that are unreactive in nature. For example, platinum.
PLEASE MARK AS BRAINLIEST
Answer:
The correct statement regarding inert chemical elements such as argon is B. They don't react with other elements to form compounds.
Explanation:
Inert elements, also known as noble gases, are located in Group 18 of the periodic table. These elements have a full outer electron shell, which makes them highly stable and unreactive. Argon, for example, has 8 electrons in its outer shell, resulting in a stable electron configuration. Since the outer electron shell is already complete, inert elements do not readily lose or gain electrons to form compounds.
This lack of reactivity is due to the fact that the energy required to remove or add an electron from the outer shell is extremely high. As a result, inert elements do not easily form chemical bonds with other elements. Instead, they exist as individual atoms or as diatomic molecules in the case of some noble gases.
To summarize, inert elements like argon do not react with other elements to form compounds because they have a stable electron configuration with a full outer electron shell.
Imagine there was a campaign to wipe out all bacteria. Why would this not be a good
idea? In your answer, include the terms amino acids, ammonia, nitrites, and nitrates as you
discuss the role of bacteria in the nitrogen cycle.
Answer:
If all the bacteria are removed from the earth, all the organisms are negatively affected.
Explanation: There are also some beneficial bacteria which helps in the nitrogen fixation called Nitrogen fixing bacteria such as Cyanobacteria and Azotobactor. These bacteria fixes atmospheric nitrogen into ammonium and nitrates form because plants are unable to use the atmospheric nitrogen, it only use nitrogen in ammonia and nitrates form. Plants absorb nitrates and form amino acid.

Explain how tillage has negative effects on the environment.
Answer:
Soil Erosion
Explanation:
Basically, tillage breaks soil up, destroying its overall structure. It encourages surface runoff and therefore soil erodes more easily. In some cases soil erosion is beneficial, but in most cases, it is not. Tillage has also been found to cause the emissions of more toxic gases such as N20.
Tillage negatively impacts the environment through soil erosion, desertification, deforestation, pollution of soil and water bodies, and lost carbon sequestration ability.
Explanation:Tillage is a farming practice that involves the physical manipulation of soil, often to prepare it for planting. However, it has negative effects on the environment. One of these effects is soil erosion, where the top layer of soil is swept away by wind or water. This reduces the fertility of the soil and, in turn, decreases the productivity of the land.
Secondly, tillage contributes to soil pollution. The method can cause desertification - converting fertile land into a desert. This is especially evident in areas where tillage is done intensively and without proper management of the soil.
Thirdly, tillage contributes to environmental degradation. It contributes to deforestation because farmland often requires clearing of forests, leading to loss of habitats and biodiversity. This intensive form of farming also leads to the build-up of greenhouse gases due to the burning of fallen trees and biomass.
Furthermore, the excessive use of chemical fertilizers in tillage releases pollutants that can leach into the soil and water bodies, which harms both the environment and human health.
Finally, carbon sequestration is also affected negatively. Normally, soil can act as a carbon sink absorbing atmospheric carbon and helping to mitigate climate change. However, due to overgrazing, damage from tilling and other factors, many of the world's soils have lost this ability, resulting in an increase in carbon dioxide levels in the atmosphere.

carbon? *
O
It is the universal solvent
It is a part of all organic compounds, including carbohydrates and nucleic acids
O
It is found in every living thing.
O
It ensures life on Earth can exist
Answer: It is a universal solvent does not accurately define carbon.
Explanation:
Carbon is not a universal solvent but water is a universal solvent because it is liquid and dissolve most compounds.
Carbon is the 15th most naturally occurring element on Earth. It is considered as part of living organisms components. It form the components of biomolecules like carbohydrates, fats, and protein which are the essential nutrients needed for cellular processes in living organisms, a requirement for survival.
Answer:
It is the universal solvent
Explanation:
That carbon is the universal solvent does not accurately define the element.
Carbon, when considered alone naturally occur as a solids. It exists freely in nature as diamond, graphite, and also a major constituent of coal.
Carbon also exist as part of all organic compounds such as nucleic acids and carbohydrates and other important biomolecules that make up life.
By definition, a solvent is a substance that is capable of dissolving a solute, resulting in a solution. Most solvents are usually in liquid forms.
Hence, that carbon is a universal solvent is incorrect.
Living things need food to survive. Plants make their own food through the process of photosynthesis, and animals get food by eating plants and/or other animals.
Through the process of cellular respiration, living things release energy from the sugar found in their food to carry out their life processes. The other substances found in the food may be excreted as waste or are most often used for
Final answer:
Beyond energy release, the substances found in food are used for building large molecules essential for bodily functions, synthesizing new cell parts, repairing tissues, and producing hormones and enzymes. The energy stored in ATP is used in numerous cellular processes.
Explanation:
Other Uses of Substances from Food Besides Energy Release
Through the process of cellular respiration, living things release energy from sugar, which is essential for carrying out life processes. However, the substances found in food are not only for energy production; they are also utilized in various other essential biological functions. The sugars and other components consumed as food are fundamental in building large molecules like proteins, lipids, nucleic acids, and complex carbohydrates. These molecules are crucial for the structure, function, and regulation of the body's cells, tissues, and organs.
In addition to energy release, food substances contribute to the synthesis of new cell components and the repair of damaged ones. This is essential for growth, maintenance, and repair of tissues. Moreover, elements from the digested food may also be involved in producing hormones, enzymes, and other critical substances for cell signaling and metabolic regulations. This complex transformation of energy and material is what maintains life functions and supports the health and continued survival of living organisms.
Finally, we must note that cells utilize the energy harvested from the breakdown of food molecules in metabolic pathways, where energy carriers such as ATP (adenosine triphosphate) are generated. ATP is then used in various cellular processes, including muscle contraction, nerve impulse propagation, and cellular transport mechanisms, to name a few.
Living things use cellular respiration to release energy from food. Other substances found in food are used for growth, maintenance, and function. These substances include proteins, fats, vitamins, and minerals.
Living things need food to survive. Plants make their own food through the process of photosynthesis, and animals obtain food by eating plants or other animals. Through the process of cellular respiration, organisms release energy from the sugar found in their food to carry out life processes. The other substances found in food, such as proteins, fats, vitamins, and minerals, are most often used for:
Growth: Proteins, for example, are crucial for building and repairing tissues.Maintenance: Fats provide structural components for cell membranes.Function: Vitamins and minerals play important roles in biochemical processes.This energy utilization and transformation highlight the critical role of food in supporting the complex needs of living organisms.

which organism transfer the most energy within the food web
Explanation:
At the bottom of a food chain is always the primary producer. In terrestrial ecosystems most primary producers are plants, and in marine ecosystems, most primary producers are phytoplankton. Both produce most the nutrients and energy needed to support the rest of the food chain in their respective ecosystems.
Final answer:
Producers transfer the most energy within a food web, as they are the source of energy converted from sunlight during photosynthesis. Energy transfer is only about 10% efficient between trophic levels, decreasing at higher levels. Warm-blooded animals use more energy compared to cold-blooded ones, affecting the energy transfer.
Explanation:
Within a food web, the organisms that transfer the most energy are typically those at the producer level, which mainly consist of photosynthetic organisms such as plants and algae. These producers harness energy from the sun and convert it into chemical energy through the process of photosynthesis, forming the foundation of the food web. Energy transfer then occurs when consumers, such as herbivores, eat the producers.
The efficiency with which energy is transferred between trophic levels is an important aspect to consider. Only about 10% of the energy at one level is typically transferred to the next level, as organisms use the majority of consumed energy for their own metabolic processes, growth, and reproduction. This concept is represented in ecological pyramids of energy, which illustrate that the amount of energy diminishes as it moves up the trophic levels from producers to primary consumers (herbivores), to secondary consumers (carnivores that eat herbivores), and so on.
It is also crucial to understand the difference in energy transfer within warm-blooded (endothermic) and cold-blooded (ectothermic) animals. Warm-blooded animals require more energy to maintain their body temperature and therefore must consume more food, which impacts the energy they transfer within the food web compared to cold-blooded animals, which are more energy efficient.

How might a flood affect the population of an area?
increase the population
reduce the population
increase available resources
reduce the need for resources
Answer: reduce the population
Explanation: The flood would increase the need for resources due to destroying them. The flood wouldn't increase the population unless it did no damage and flooded in an area they set up to get flooded. Also a flood wouldn't increase available resources because it destroys them ( trees, food in a house, plants, equipment, and homes).
A flood can have a significant impact on the population of an area, and typically, it is more likely to reduce the population, which is the second option, as a flood is more likely to reduce the population of an area than increase it and washes the organisms both biotic and abiotic.
What is a flood?When a flood occurs, it can have a variety of negative impacts on the local population. One of the most significant impacts is displacement and migration. Floods can destroy homes, infrastructure, and other vital resources, making it unsafe or impossible for people to remain in affected areas. As a result, people may be forced to relocate temporarily or permanently, which can result in a decline in the local population. Recently, man-made causes caused the recent flood, as climate change was the main reason behind it.
Hence, a flood can have a significant impact on the population of an area, and typically, it is more likely to reduce the population, which is the second option.

Selective breeding
Explanation:
A farmer grows beans that he sells to local markets. Over a period of 40 years, the farmer has identified the plants that produced the most beans, and only used those beans to produce new plants. This procedure is part of the process of artificial selection.
The farmer's practice of selecting beans from plants with higher yields to produce new plants is an example of artificial selection, a form of selective breeding used in agriculture to improve and sustain crop quality and productivity over time. Artificial selection, also known as selective breeding, is a process where humans actively choose which plants or animals breed based on specific traits they wish to propagate. This method has been used for thousands of years to improve crop yields, enhance food flavor, and develop resistance to pests and diseases. In the case of the farmer, by selecting the plants that produced the most beans, he is essentially ensuring that the desirable traits of high yield are passed down to future plant generations. This practice aids in progressively improving the crop's quality and productivity over time.
Artificial selection is a crucial technique in agriculture for enhancing and sustaining food production. It allows farmers to cultivate crops that are better suited to human needs and environmental conditions by selectively breeding plants with desirable characteristics.
