If you lost the ability to sweat, Dehydration occurs when the fluid lost through sweating is not sufficiently replaced.
Sweating too little can pose potentially serious health risks. Strenuous exercise, hard physical labor, or hot weather can lead to heat cramps, heat exhaustion, and even heat stroke if decreased sweating affects large parts of the body and prevents adequate cooling.
The number one reason for not sweating is dehydration. If you don't drink enough water before and after exercise, your body is at risk of becoming severely dehydrated. Sweat is mostly water, so not having enough in your body means you can't produce enough sweat. Very healthy people sweat more than unhealthy people.

Kelp forests are a very important ecosystem in marine waters by supporting important biodiversity. These kelp forests are threatened by all of the following except presence of large predators.
Kelp forests are an incredibly important marine ecosystem that provide a variety of benefits to the surrounding environment. They are a prime source of habitat and food for a large variety of species, including fish, invertebrates, and even certain species of seabirds. In addition, kelp forests also act as a type of buffer, protecting coasts from erosion and providing habitat for juvenile fish, which helps to maintain coastal fish populations. Unfortunately, kelp forests are threatened by many factors, including overfishing, pollution, and climate change.
The one factor that does not threaten kelp forests is the presence of large predators. While large predators can have a significant impact on the overall structure of a kelp forest, they are not directly responsible for the decline and destruction of kelp forests. For example, while sea otters, seals, and sea lions can have a significant impact on kelp forests by over-browsing, they are not the cause of the decline in kelp forests.

b. Reproduce and increase gene frequency in the population
c. Survive and mate
d. Produce offspring that can react at an average speed
The correct answer is option (A) Reduce the mortality rate of the population.
Natural selection is a pressure that causes groups of organisms to change over time. Animals inherit their genetics from their parents or ancestors, and the environment is constantly changing. So, no organism is perfectly adapted to its environment. Thus, natural selection is constantly influencing the evolution of species.
The environment will change, even if a parent was perfectly acclimated to it, leaving the offspring poorly adapted to it. Only the best and fittest organisms can reproduce since there are many species and few resources. Natural selection, which is thought of as the environment and forces acting to prevent organisms from surviving and reproducing, operates against all living things.

What is carbon dioxide’s indirect effect on other species in a marine food chain?
Carbon dioxide (CO2) has an indirect effect on other species in a marine food chain through its role in the process of photosynthesis. Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy, using CO2 and water as reactants. Oxygen is produced as a byproduct of photosynthesis.
In a marine food chain, photosynthesizing organisms, such as algae and seaweed, are primary producers. They form the base of the food chain, providing energy for other organisms, such as herbivores, which feed on them. Higher up the food chain, carnivores feed on herbivores and other carnivores, and so on.
The indirect effect of CO2 on other species in a marine food chain is through its role in photosynthesis, which provides the energy that forms the base of the food chain. If the concentration of CO2 in the water is too high, it can interfere with the process of photosynthesis, leading to reduced growth and productivity of photosynthesizing organisms. This can have cascading effects on the rest of the food chain, as the reduced availability of energy at the base of the food chain can lead to decreased population sizes and reproductive success of higher level consumers.

C. nitrogen oxides.
D. particulate matter.
E. VOCs
Particulate Matter (PM) is the air pollutant least successfully removed from the air by technologies in developed nations.
Particulate matter is a mixture of solid particles and liquid droplets found in the air. Particulate matter is made up of liquid droplets, dust, dirt, soot, and smoke.
Particulate matter can be inhaled and can cause serious health problems, including respiratory and cardiovascular disease. PM is generated by a variety of sources including combustion, construction, and natural sources such as dust storms.
While many technologies have been developed to reduce PM emissions, they are not always effective in removing PM from the air, especially in heavily industrialized areas due to several factors.
One major reason is that particulate matter can come from a wide variety of sources, such as industrial emissions, transportation, agriculture, and natural sources such as dust storms and wildfires. This makes it difficult to target and effectively reduce the sources of particulate matter.
Another reason is that particulate matter can be transported over long distances by winds, making it difficult to contain and control. This means that even if local sources of particulate matter are reduced, it can still be a problem due to pollution from other areas.
Additionally, particulate matter is very small and can be hard to filter out of the air. The cost and technology required for filtration systems, like HEPA filters or electrostatic precipitators, can be expensive and challenging to implement, especially in developing countries.
In conclusion, particulate matter is a challenging air pollutant to remove, due to its various sources, its transportability, and the difficulty of filtration. A multi-pronged approach including reducing the sources, controlling emissions, and using advanced filtration systems is needed to effectively reduce particulate matter in the air.

The following metabolic pathway involves the action of many enzymes within a cell.
Substrate 1 --> Substrate 2 --> Substrate 3 --> Product
Explain what would happen to the amount of product produced if the enzyme that acts on substrate 2 was not produced in the cell. All other enzymes at each step of the pathway are present.
Answer:
The metabolic pathway you described involves a series of chemical reactions that convert one substrate into the next substrate until the final product is formed. If the enzyme that acts on substrate 2 is not produced within the cell, the reaction that converts substrate 1 into substrate 2 would not occur. This would cause a block in the pathway, as substrate 2 would not be available for the enzyme that converts substrate 2 into substrate 3.
Explanation:
The metabolic pathway you described involves a series of chemical reactions that convert one substrate into the next substrate until the final product is formed. If the enzyme that acts on substrate 2 is not produced within the cell, the reaction that converts substrate 1 into substrate 2 would not occur. This would cause a block in the pathway, as substrate 2 would not be available for the enzyme that converts substrate 2 into substrate 3.
As a result, the amount of product produced would be severely decreased. Because of the missing enzyme, substrate 2 would not be converted into substrate 3, and subsequently, substrate 3 would not be converted into the final product. If this key enzyme is not present, the entire metabolic pathway would be halted at the step involving substrate 2, causing the cells to be unable to produce the final product and creating a bottleneck in the metabolic pathway.
It's important to remember that enzymes are catalysts, they speed up the reactions of the metabolic pathway and ensure the reactions occur at appropriate rates to support life, even a small change in the enzyme activity can affect the entire pathway and alter the final product quantity and quality.
