Sure, here's a condensed study guide for cellular respiration, ATP, and photosynthesis:

Process by which cells break down glucose and other organic molecules to produce energy (ATP) and release carbon dioxide and water as waste products.

Consists of three stages: glycolysis, the Krebs cycle, and the electron transport chain.

Glycolysis occurs in the cytoplasm and generates a small amount of ATP and NADH.

The Krebs cycle takes place in the mitochondria and produces more ATP, NADH, and FADH2.

The electron transport chain occurs in the mitochondria and generates the most ATP through oxidative phosphorylation.

Adenosine triphosphate (ATP) is the energy currency of cells.

Consists of adenosine and three phosphate groups.

Energy is released when the last phosphate group is removed, forming adenosine diphosphate (ADP).

ATP is regenerated by adding a phosphate group back to ADP through phosphorylation.

Process by which plants and other organisms convert light energy into chemical energy (glucose).

Occurs in chloroplasts and consists of two stages: the light-dependent reactions and the light-independent reactions (Calvin cycle).

Light-dependent reactions occur in the thylakoid membrane and generate ATP and NADPH.

Light-independent reactions occur in the stroma and use ATP and NADPH to fix carbon dioxide into glucose.

Answer: Living Planet Index

Explanation:

The Living Planet Index is a survey measure of global biodiversity status based on the population abundance of vertebrate species in terrestrial, freshwater and marine habitats. We have to consider that a population is defined as a species within a geographical area. It is used as a source of information to identify threats at the population level for each species on Planet Earth.  

With this analysis, an overall decline of about 60 percent in population size has been seen between 1970 and 2014. The decline in species populations is particularly greatest in the tropics, with South America and Central America suffering the most dramatic decline. The numbers of freshwater species have also declined dramatically. However, measuring biodiversity (all the varieties of life that can be found on Earth and the relationships between them) is complex, so the index should consider indicators to measure changes in species distribution, extinction risk and changes in community composition.  

The goal of the Living Planet Index is to achieve and promote global conservation of animals and their habitats.

About 90% of the water in the atmosphere is produced from evaporation crom water bodys, while the remaining 10% comes from transpiration. These are the form of return of the water to the atmosphere in the water cycle. The rainfall is related to the process of precipitation of the water cycle, being know a the return of water to the Earth.

Therefore, for the information about the water cycle and how it work, the alternative is false because according to the known about the water cycle, rainfall is not direct linked to the return of water to the air, but to the return of water to the Earth.

By most standards, Homo sapiens group is a successful species. It has dominated the planet earth.

Humans are the only known species to have developed complex societies. We have advanced technology, art, music, literature, science, and a well-established language system. We have also developed a civilization that supports over 7 billion people.

Homo sapiens have indeed altered the face of the planet in several ways. Our civilization has cleared out forests, drained wetlands, polluted water bodies, and even removed entire mountains for the extraction of resources. We have built large dams, highways, buildings, factories, and other structures that have changed the landscape in significant ways. Our presence has also impacted various ecosystems, and many species have gone extinct due to human activities.

Despite the changes that humans have made to the planet, we still have a chance to prevent further damage. The focus should be on developing sustainable practices that would help conserve the natural environment. We need to ensure that future generations have access to clean water, fresh air, and healthy ecosystems. We should also focus on mitigating the negative impacts of human activity on the environment.

Efforts are being made to address threats to tropical rainforests, including deforestation, climate change, and habitat loss. Some of these solutions involve sustainable forestry practices, reforestation, conservation programs, and international cooperation.

1. Sustainable forestry practices aim to balance the need for wood products with the preservation of the ecosystem. This includes selective logging, reduced-impact logging, and certification programs like the Forest Stewardship Council (FSC).

2. Reforestation involves planting trees to replace those that have been cut down or destroyed. This helps to restore the ecosystem, absorb carbon dioxide, and support biodiversity.

3. Conservation programs work to protect rainforest habitats and species through the creation of protected areas, such as national parks and wildlife reserves. These efforts can help prevent habitat loss and promote biodiversity conservation.

4. International cooperation, such as the United Nations Framework Convention on Climate Change (UNFCCC) and the REDD+ program, brings countries together to address the global challenges of deforestation and climate change.

While these solutions are helping to mitigate some of the threats to tropical rainforests, more work is needed to ensure the long-term preservation of these valuable ecosystems. Continued efforts in education, policy-making, and international collaboration are crucial to achieving this goal.

Answer:

Ecological succession in different ecosystems can be studied by first of all recognizing the various ecosystems and what makes them unique. Thereafter, sample collection methods and regimen must be established with standardized experiments for establishing diversity of organisms in the ecosystem. Regular data storage and interpretation is needed to know what goes on in the ecosystem and at what time.

Explanation:

To study ecological succession in a fermented food sample, for example, palm-wine, methods such as metagenomics can be used to determine the diversity of organisms at various points from the tapping stage through various hours of alcoholic fermentation. This will reveal the initial colonizers of the sample and what happens to them as the pH of the palm-wine changes. Eventually, only organisms that can tolerate high acidity will thrive as the fermentation proceeds.

Water is oxidised within the plant cell, which means it loses electrons, but carbon dioxide is reduced, which means it receives electrons. This converts water to oxygen and carbon dioxide to glucose.

Compositional changes can also be used to characterise oxidation and reduction. Because the original definition of oxidation was "adding oxygen," when oxygen is added to a molecule, it gets oxidised. In the case of reduction, if a molecule loses oxygen atoms, the molecule is reduced.

Carbon dioxide is converted to glucose during this process, while water is oxidised when it splits to release electrons, protons, and atomic oxygen.

The proportion of the carbon dioxide exhaled derived from the oxidation of pyruvate to acetyl CoA is 1/3.

Pyruvate is produced by glycolysis in the cytoplasm and its oxidation takes place in the mitochondrial matrix before chemical reactions begin, pyruvate enters the mitochondrion crossing the inner membrane and arriving at the matrix.

Pyruvate + NAD⁺ + CoA-SH ⇒ acetyl-CoA + NADH + CO₂

This is the reaction of the conversion of pyruvate into acetyl CoA.

1 molecule of pyruvate is converted into 1 molecule of carbon dioxide.

Also, 2 molecules of pyruvate are converted into 2 molecules of carbon dioxide (as glucose on glycolysis yields 2 molecules of pyruvate).

Acetyl-CoA also contributes to the citric acid cycle and generates two molecules of CO₂.

Pyruvate thus generates a total of 3 molecules of CO₂, whereas glucose generates 6 molecules of CO₂ (as glucose on glycolysis yields 2 molecules of pyruvate)

Thus, Fraction = 2/6 = 1/3.
