Explain where the enzymes for electron transport are located in bacteria (prokaryotes) if they don't have internal membranes, and therefore do not have a mitochondria

Answers

Answer 1

In bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

Bacteria lack mitochondria, i.e. bacteria have no membrane-bound organelles.

In consequence, bacterial enzymes responsible for the electron transport chain are localized in the plasma membrane.

The electrochemical proton (H+) gradient required to create Adenosine triphosphate (ATP) from ADP and phosphate (Pi) is generated across the plasma bacterial membrane.

In bacteria, the electron transport chain is generally shorter and contains a lower phosphorus-oxygen ratio than the mitochondrial (eukaryotic) electron transport chain.

In conclusion, in bacteria, all enzymes responsible for the electron transport chain are located in the CELL MEMBRANE.

When rain changes to ice pellets what happens to the temperature?

Answers

Explanation:

When rain changes to ice pellets, the temperature at the surface usually drops. This is because the process of rain changing to ice pellets, also known as sleet or graupel, involves the raindrops passing through a layer of freezing air near the surface. As the raindrops fall through this layer of cold air, they freeze into ice pellets.

This process releases latent heat, which is the energy absorbed or released by a substance during a change in state. In this case, as the water droplets freeze into ice pellets, they release latent heat, which slightly warms the surrounding air. However, this warming effect is generally offset by the cooling effect of the freezing air near the surface, resulting in a net drop in temperature.

It's worth noting that the specific temperature change will depend on various factors, such as the temperature and humidity of the air mass, the intensity of the precipitation, and the duration of the sleet or graupel event. In some cases, the temperature drop may be relatively small, while in other cases, it may be more significant.

The temperature suddenly becomes colder.

If the gasoline floats on the surface of the puddle, what does that tell you about how its density compares to that of water? Explain your answer.

Answers

It tells that gasoline is less dense than water, because according to Archimedes Law states that any body completely or partially submerged in a fluid is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid, displaced by the object. So, when gasoline is put in water, it floats, it means that the buoyancy force is greater than gasoline's weight. It means that the weight of the same volume of water is more than the weight of the same volume of gasoline. It means that water has more density.

It tells that the gasoline has a lower density because it is floating in water else it will sink.

how do creationists and evolutionists differ in their views of natural selection?

Answers

Answer: creationists believe in higher power to create things as is and evolutionists believe we originate from a common past and constantly change

Explanation: Creationists believe the belief that the universe and living organisms originate from specific acts of divine creation, as in the biblical account, rather than by natural processes such as evolution.

The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.

How does passive transport come into play in oxygen's journey through our body?

Answers

Oxygen is often diffusing from the air inside the alveoli within the lungs into the erythrocytes and blood plasma. If you don’t know diffusion is a type of passive transport where molecules move from high concentration to low concentration. So therefore means that the concentration of oxygen in the air must be higher than it is in the blood.

In the alveoli of the lungs, oxygen frequently diffuses from the air into the erythrocytes and blood plasma.

What is passive transport?

Diffusion is a form of passive transport where molecules migrate from a high concentration to a low concentration, if you didn't know. Therefore, it follows that the oxygen content of the air must be higher than that of the blood.

Passive membrane transport methods are the most direct. Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.

Diffusion is the process by which chemicals travel passively from a region of higher concentration to a region of lower concentration.

Therefore, Passive transport is a term that refers to both osmosis and diffusion. They don't need any power.

Does the pattern in a food chain support the conclusion that climate change is caused by human activity and deforestion? Why or Why not?

Answers

Answer: No, it does not directly.

Explanation:

The pattern in a food chain cannot directly support the conclusion that climate change is caused by human activity and deforestation, as food chains only describe the transfer of energy and nutrients between different organisms in an ecosystem. However, the impacts of climate change and deforestation can disrupt food chains and have cascading effects on ecosystems, which can ultimately lead to the extinction of certain species and the loss of biodiversity.

Human activities, such as burning fossil fuels, deforestation, and agricultural practices, contribute to the emission of greenhouse gases, which trap heat in the atmosphere and cause global temperatures to rise. This increase in temperature can have a range of effects, including changes in precipitation patterns, rising sea levels, and more frequent and intense extreme weather events.

These changes can disrupt the habitats and food sources of many species, causing declines in their populations and even extinction in some cases. For example, deforestation can lead to the loss of habitat for many species, including those that are important components of food chains. Additionally, changes in precipitation patterns can affect the growth of plants and the availability of food for herbivores, which can then impact the populations of predators that depend on these herbivores for food.

In summary, while the pattern in a food chain itself does not provide direct evidence for the causes of climate change, the disruption of food chains and ecosystems due to human activities and deforestation can contribute to climate change and its impacts.

No, a food chain's pattern does not conclusively prove that human activity and deforestation are to blame for climate change.

            The pattern in a food chain does not necessarily prove that human activity and deforestation are to blame for climate change. Natural processes, greenhouse gas emissions, changes in land use, and other factors are only a few of the many influences on the complex phenomenon known as climate change. While human actions like burning fossil fuels can raise greenhouse gas concentrations and deforestation can lessen carbon sinks and release stored carbon into the atmosphere, these factors cannot simply be attributed to the pattern in a food chain.

         A thorough examination of the diverse scientific facts and evidence from numerous disciplines, such as atmospheric sciences, climatology, and earth sciences, is necessary to comprehend and handle climate change.

S - Savannas tend to have more trees and shrubs.

S - Savanna's climate is drier than that of a grassland.

G - Grasslands are found in temperature regions.

G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.

G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.

B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.

B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.

B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
