This answer is supported by scientific research and makes sense based on the principles of photosynthesis. However, it's important to note that scientific knowledge is continuously evolving, and there may be further advancements or refinements in our understanding of photosynthesis and its relationship with light intensity since my knowledge cutoff in September 2021.

Based on the available data up until September 2021, it is well established that the intensity of light significantly affects the rate of photosynthesis in plants. Photosynthesis is the process by which plants convert light energy into chemical energy (glucose) that they can use as a source of fuel.

In general, as the intensity of light increases, the rate of photosynthesis also increases, up to a certain point. This relationship is often described by the concept of the "light saturation point." At low light intensities, the rate of photosynthesis is limited by the availability of light energy. As the light intensity increases, the rate of photosynthesis also increases because more photons are available for the plant to capture and convert into chemical energy.

However, beyond a certain light intensity, the rate of photosynthesis reaches a maximum level, and further increases in light intensity do not lead to a proportional increase in the rate. This is because other factors, such as the availability of carbon dioxide or the capacity of the plant's biochemical processes, become limiting factors.

The mangrove forest which holds the most Carbon dioxide followed by forest shown by second image and at last the vegetation on farms holds and releases the least amount of Carbon dioxide.

Carbon is transferred through one storage reservoir to another through a range of mechanisms. Plants, for example, transfer carbon dioxide from the atmosphere into the biome via photosynthesis in the food chain. They use solar energy to chemically incorporate carbon dioxide, hydrogen, and oxygen from water to form sugar molecules. Animals that consume plants metabolize the sugar molecules to obtain energy. Respiration, excretion, and decomposition all return carbon to the atmosphere or soil, thus completing the cycle.

Erosion, for example, releases carbon into the atmosphere slowly, whereas volcanic activity releases it quickly. Another way to quickly release carbon into the atmosphere is to burn fossil fuels in automobiles or power plants.

Answer:

NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.

During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.

In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.

Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.

Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.

In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.

The unofficial titles of some eras such as Age of Fishes, Age of Reptiles and Age of Mammals are really informative and they are not oversimplifications because these periods reflect the emergence of different taxonomic groups in the course of evolution.

The animal eras are periods during the geological time in which certain groups of animals appeared in the course of evolution, which results informative to determine how evolution (change) occurred due to natural selection.

For example, mammals emerged as a taxonomic group during the Cenozoic Era, which occurred approximately 65 million years ago and this period is known as the Age of mammals.

Therefore, with this data, we can see that an animal era is not only an oversimplified term because it also involves the emergence of certain taxonomic groups during the evolution and can serve to contextualize geological periods in a biological framework.

That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.

Answer:

A. It's the pursuit and application of knowledge and understanding of both the natural and social world.

Answer:

farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

Explanation:

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.

Other factors that affect the rate of erosion in an area include the following; farm management, rainfall, climate, soil type, soil cover, landscape, type of wave, crops, rock strength and position of coast.

Answer:

The genetic code is degenerate and therefore mutations may go unnoticed.

Explanation:

Each triplet of nucleotide bases, which is known as a codon, encodes for a specific amino acid during translation. However, a single amino acid may be coded by different codons. It is for that reason that the genetic code is considered to be degenerate. In this case, Lysine amino acid can be encoded by both TTT (UUU in the mRNA) and TTC (UUC) codons, thereby a mutation T>C at the third nucleotide codon position does not affect the resulting protein (i.e., it is a silent mutation).
