Answer:

because nutrients cannot be stored in the soil for a long time  

Explanation:

In rainforests, high temperatures and humid conditions lead to the rapid decomposition of the organic matter in the soils, which releases nutrients rapidly. However, rainforest soils are poor in nutrients due to rains that wash dead organic material from them. Moreover, rainwater is filtered naturally into the ground, thereby extracting (leaching) nutrients off the surface.

The process of fermentation differs in yeast dough and muscles in terms of the end products and the purpose of fermentation.

In yeast dough, fermentation is primarily carried out by yeast cells. Yeast consumes sugars present in the dough and produces carbon dioxide gas as a byproduct. This gas gets trapped in the dough, creating air pockets, and causing the dough to rise. The fermentation process in yeast dough is used to leaven the dough, making it light and fluffy when baked.

On the other hand, fermentation in muscles, specifically during intense physical activity, involves a different mechanism. Muscles undergo anaerobic respiration when there is a lack of oxygen supply. This anaerobic respiration leads to the production of lactic acid as a byproduct. The buildup of lactic acid in muscles causes fatigue, cramping, and discomfort.

City planners faced with the question of balancing concerns regarding mosquitoes in wetland restoration projects need to consider both the potential benefits and risks involved. On one hand, mosquitoes can serve as a food source for birds and contribute to the biodiversity and ecological balance of the wetland ecosystem.

They play a role in supporting the bird population and enhancing the natural beauty of the park. These aspects can be important factors in promoting environmental sustainability and attracting visitors to the area. On the other hand, there are legitimate concerns about the potential risks associated with mosquitoes, particularly in terms of disease transmission. While malaria is not typically a concern in the United States, other mosquito-borne diseases such as West Nile virus and Zika virus may pose risks to public health. As migration patterns change and more people move from regions where these diseases are prevalent, the potential for transmission could increase.

To strike a balance, city planners should consider implementing measures to mitigate the risks associated with mosquitoes while maximizing the benefits of wetland restoration. This can include implementing mosquito control strategies such as monitoring and targeted insecticide use, creating habitats for natural predators of mosquitoes, and providing education and awareness programs for the public. By adopting a comprehensive approach that addresses both ecological and public health considerations, city planners can create a wetland restoration project that balances the promotion of biodiversity and natural beauty with the protection of public health.

Explanation:

Most of the ATP made during the complete oxidation of glucose to CO2 and water is synthesized by the (A) mitochondrial ATP synthase.

The process of ATP synthesis in the mitochondria is known as oxidative phosphorylation.

It occurs through a series of electron transport chain reactions, which generate a proton gradient across the inner mitochondrial membrane.

The flow of protons back into the mitochondrial matrix through the ATP synthase enzyme drives the synthesis of ATP from ADP and inorganic phosphate.

This process is highly efficient and accounts for the majority of ATP production during cellular respiration.

Substrate-level phosphorylation, which occurs during glycolysis and the citric acid cycle, contributes to a smaller fraction of ATP production.

Answer:

Esophagus

Explanation:

In the digestion and absorption of food, the esophagus is the least involved.

It is a part of the digestive system, but all it does is simply pass the food down to the stomach.

The one that is least involved in the mechanical breakdown of food, digestion, or absorption is esophagus. The correct option is d.

Even though it is a vital component of the digestive system, the esophagus plays a much smaller role in the mechanical digestion of food than the other alternatives.

A muscular tube called the esophagus moves food from the mouth to the stomach by a process known as peristalsis, which calls for repetitive muscle contractions.

Its main job is to push food down the digestive tract so that it can travel more easily. Food is mostly mechanically broken down in the mouth while being chewed by the teeth and in the stomach while being churned by muscles.

The majority of digestion and nutrient absorption occurs in the small intestine.

Thus, the correct option is d.

Answer:

C

Explanation:

Answer:

Variation. There must be variation in the traits of the individuals in the population, and some of this variation must be heritable, meaning it can be passed on to offspring.

Inheritance. The traits that vary among individuals must be encoded in the genes or have a genetic basis. Otherwise, they could not be inherited by the next generation.

Differential survival and reproduction. Individuals with certain traits must survive and reproduce more successfully than others in a given environment. This means that they have a higher fitness, or reproductive success, than others.

Time. Evolution by natural selection takes place over many generations. It is not a one-time event, but a gradual process of change in the population.

If these factors are present, then natural selection is likely to be the mechanism of evolution for that species. Natural selection causes populations to become adapted, or increasingly well-suited, to their environments over time2.

Answer:

The correct answer is "photorespiration".

Explanation:

Photorespiration is a process in plants, where molecular oxygen is taken in a light-dependent  manner. Photorespiration is often considered a wasteful pathway because it competes with the Calvin cycle, which is much more efficient. In C3 plants the conservation of water promotes photorespiration. This occurs when the C3 plants close its stomata because the environment its too hot, or the carbon dioxide concentration drops to about 50 ppm.

The correct answer is C. probably evolved from one single ancestral species from the mainland. Darwin realized that Finches differed form their relatives in mainland.

Explanation:

Answer: The products of light-independent reactions are glucose and other organic compounds, which are essential for the survival of plants and other photosynthetic organ

Explanation:

Light-independent reactions, also known as the Calvin cycle or the dark reactions, are a series of biochemical reactions that occur in the stroma of chloroplasts in photosynthetic organisms such as plants, algae, and some bacteria. These reactions are called "light-independent" because they do not require light energy to occur, unlike the light-dependent reactions that take place in the thylakoid membranes.

The Calvin cycle can be divided into three stages:

Carbon fixation: In this stage, atmospheric carbon dioxide (CO2) is captured by an enzyme called RuBisCO (ribulose-1,5-bisphosphate carboxylase/oxygenase) and added to a five-carbon sugar called ribulose bisphosphate (RuBP) to form a six-carbon molecule that quickly breaks down into two molecules of 3-phosphoglycerate (3-PGA).

Reduction: In this stage, ATP and NADPH, which are products of the light-dependent reactions, are used to convert the 3-PGA molecules into glyceraldehyde-3-phosphate (G3P), a three-carbon sugar.

Regeneration: In this stage, some of the G3P molecules are used to regenerate RuBP, which can then enter the carbon fixation stage again. The remaining G3P molecules are used to synthesize glucose and other organic compounds, which are the ultimate products of photosynthesis.

Overall, the net reaction of the Calvin cycle is:

6 CO2 + 18 ATP + 12 NADPH + 12 H+ → C6H12O6 (glucose) + 18 ADP + 18 Pi + 12 NADP+

The products of light-independent reactions are glucose and other organic compounds, which are essential for the survival of plants and other photosynthetic organ
