The digestive system is responsible for breaking down food into nutrients that can be absorbed by the body, as well as eliminating waste products. The main organs involved in the digestive system are the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.

Mouth: Digestion begins in the mouth, where teeth and the tongue work together to chew and grind food into small pieces. Saliva, produced by the salivary glands, contains enzymes that begin to break down carbohydrates.

Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. It uses muscular contractions called peristalsis to move food down into the stomach.

Stomach: The stomach is a muscular sac that mixes and grinds food with gastric juice, which contains hydrochloric acid and enzymes that break down proteins. The stomach also has a thick mucous lining that protects it from the acid.

Small intestine: The small intestine is where most of the nutrients from food are absorbed into the bloodstream. It is about 20 feet long and has three sections: the duodenum, jejunum, and ileum. Enzymes from the pancreas and liver, as well as from the small intestine itself, break down carbohydrates, proteins, and fats into their building blocks. Nutrients are then absorbed through the intestinal lining and transported to the liver.

Large intestine: The large intestine, or colon, is responsible for absorbing water and electrolytes from the remaining food waste, forming feces. The colon is also home to billions of bacteria that help break down certain undigested carbohydrates and produce vitamins like vitamin K.

Rectum: The rectum is the final portion of the large intestine. It stores feces until they are eliminated.

Anus: The anus is the opening at the end of the digestive tract through which feces are eliminated from the body. The anus is surrounded by two circular muscles called sphincters that control bowel movements.

The correct sequence of the common pathway of blood clotting from the beginning to the end is as follows:

The mechanism of blood clotting initiates when there is damage to a blood vessel. Platelets immediately begin to stick to the cut edges of the vessel and liberate chemicals in order to attract even more platelets. A platelet plug is formed, and the external bleeding stops.

The mechanism of blood coagulation takes initiated with the injury or when blood is leaked. Whenever there is a rupture of blood vessels or damage is caused to blood, a complex of substances called the prothrombin activator complex is formed.

The activators of prothrombin convert prothrombin into thrombin. Thrombin acts as an enzyme and converts fibrinogen into fibrin threads. These threads have now formed a polymer and activate factors that terminate the entire process.

Therefore, the correct sequence of the common pathway of blood clotting from the beginning to the end is well described above.

Explanation:

Answer:

The major cause of negative human treatment of our aquatic biomes include pollution and overfishing. It can however be slowed down by less dependence of aquatic animals for food in order to preserve the aquatic biomes.

Advocacy should be done also to sensitize people about the effects of pollution and overfishing in water bodies. Pushing for the enforcement of rules protecting the aquatic biomes from pollution should also be taken note of to improve the conditions of the biome.

Answer:

To stimulate political work in order to stimulate the development of laws aimed at avoiding the direct effects of overfishing, water pollution, runoff of fertilizer into rivers, wastes, and industrial dumpling. In addition, these debates should be also aimed at declaring protected aquatic habitats  

Explanation:

Freshwater biomes include, for example, lakes, rivers and streams; while marine biomes include coral reefs and abyssal zones.  

Aquatic habitats have a delicate equilibrium that is broken by anthropogenic activity (or natural events), which is observed by the sudden increase of algae when water bodies are treated with contaminants.

Human activity is known to produce ecological disasters into aquatic environments. For example, the oil spill into the sea produces irreversible damages to the marine habitats, thereby higher political efforts must be made to evaluate how to avoid these ecological problems.

Answer:

The amount of fossil fuels formed is much less than the amount used.

Explanation:

Fossil fuels, which include petroleum, coal, natural gas etc are an example of non-renewable sources of energy. They are termed non-renewable because they are sources that gets exhausted quickly without replenishment.

One of the characteristics of non-renewable sources of energy is that they get exhausted faster than they can be produced. Hence, regarding fossil fuels as an example of non-renewable source of energy, this means that the amount of fossil fuels formed is much less than the amount used.

Sometimes debris, submerged trees, or fences can become hazards for those engaged in water rescues. These hazards are called strainers.

A strainer can be any object which allows the water to pass through but obstructs the passage of a person. Examples of strainers include cars, trees, man-made barricades and debris.

Strainers are life-threatening obstacles which should be avoided while a person is in water. A strainer can trap a person very easily. It does not require much current to grab and submerge a swimmer.

If a person is on a boat or craft approaching a strainer, the best way to cope is to try to get to shore above it and navigate around the obstacle.  However, a swimmer should aggressively work to swim around the strainer.
