How many senses are there?

The five human senses coincide with five organs in the body. A person uses his eyes for vision, his nose for smell, his ears for hearing, his mouth for taste, and all of his skin for touch. Each of the five senses are very important to the health of a person, since humans use at least one of their senses each second of every day. Even while people sleep, they are utilizing their senses to stay alert throughout the night.

What does the corpus callosum do?

The corpus callosum integrates the cognitive, motor and sensory functions of the brain's right and left hemispheres. It allows the brain to interpret the visual field as a unified whole by integrating sensory information from the eyes.\nFull or partial absence of the corpus callosum, a congenital disorder known as agenesis of the corpus callosum, is usually diagnosed in the first two years of life and generally results in seizures, delays in mental and physical development and problems with hand-eye coordination. However, the condition is rarely fatal, and with treatment many sufferers ca..

What happens during photosynthesis?

Photosynthesis occurs in plants and in some algae. The process takes place in the chloroplasts, primarily in plant leaves. Carbon dioxide enters the leaves through the stomates by diffusion, and water is transported to the leaves in the xylem. The energy harvested through light reaction is stored by forming adenosine triphosphate, or ATP, a chemical compound used for energy storage. This process is called the "dark reaction" and takes place in the stroma. During the Calvin cycle, carbon dioxide and energy from ATP are used to create sugar. Oxygen exits the leaves through the stomata by diffusi..

What is the molar mass of potassium nitrate?

Potassium nitrate contains one atom of potassium, represented by the chemical symbol K, for a total weight of 39.09 grams per mole. It also contains a single atom of nitrogen, depicted by the symbol N, which has a weight of 14 grams per mole. It contains three atoms of oxygen, each with an individual weight of 15.99 grams per mole, for a total of 47.97 grams per mole.

What are some defense mechanisms used by plants?

Basal resistance is a function of plant cellular sensitivity, according to the American Phytopathological Society. Plant cells can sense the presence of certain bacterial organisms and can promote reactions within the plant that make it harder for those organisms to invade and effect change. All plant cells within the plant fortify themselves against being invaded or tampered with by pathogens or by microbial organisms.Hypersensitive response is cellular suicide committed on a variable scale, ass stated by the American Phytopathological Society. When plants detect infection, they induce suicid..

What is the nickname for mercury?

Mercury has been known since antiquity, when alchemists tried to turn the metal into gold and silver. It is rarely found in pure form in nature; rather, it's mostly obtained from cinnabar (HgS.) Mercury is toxic to humans. It can enter the body through digestion, inhalation or through the skin. Symptoms of mercury poisoning include nausea, headaches, tremors and ulcerations. If enough mercury is accumulated in the body, it can eventually cause death.

What are fragile ecosystems?

Fragile ecosystems are found around the world and include ocean habitats, estuaries, rainforests and floodplains. Such ecosystems play significant contributing roles to maintaining environmental stability on broader regional and national levels. They are easily harmed by human activities such as agriculture and clear-cutting of forests as well as natural disasters such as floods, earthquakes and hurricanes.

How does the rock cycle work?

Igneous rock is often recognized as a starting point for the cycle. It forms when magma cools, either above or below ground, and solidifies into crystal form. If the igneous rock is above the surface, weather and erosion can break the rock up into sediments. Time and pressure cement the pieces together into sedimentary rock. If it is located below the Earth’s crust, igneous rock can become metamorphic rock. It must be heated to a temperature of 300 to 700 degrees Celsius for this transformation to occur. This change can also be accomplished by heat generated by tectonic plate movement.\nThro..

How do you find reliable 20-day weather forecasts?

According to Time and Date, there are four different types of weather forecasting. The first is short-range, and predicts weather patterns in a forty-eight hour time frame. An extended forecast predicts weather from three to five days, while a medium range predicts from three to seven days. The least accurate is a long range forecast which predicts weather for seven or more days. Because of the length of time, the weather has the potential to change before the predicted date because it is difficult to accurately predict over a long period of time.

What is time-space convergence?

This convergence concept studies the evolving relationship between time and space, specifically how technological advancements in communication and transportation impact the relationship. Time-space convergence is aligned with the concept of speed, which indicates the amount of distance that is travelled over a specified time period.\nTime-space convergence is measured using travel time information for at least two locations and two time periods. Through technological advancements in communications and transport, the cost, time and effort expended to reach distant locations shrinks considerabl..
