Who discovered magnetism?

Gilbert also discovered that beating wrought iron could induce magnetism and that heating the iron could cause the magnetism to dissipate. This ultimately lead to the creation of more magnets. Gilbert's 1600 book "De Magnete" revolutionized the way Europeans thought about magnetism and electricity, becoming the standard in its field of study. Before Gilbert, magnetism was believed to be caused by supernatural forces.

What is the habitat of a green algae plant?

Green algae tends to live in freshwater habitats in areas where they have access to light, which is necessary in order for them to make food. In addition, green algae must live in oxygenated water in order to breathe and thrive. Algae also needs to absorb nutrients like nitrogen to exist, so this is another requirement for the plant's habitat.\n\nDepending on the species of green algae, the exact habitat may vary. Some species prefer warmer water temperatures, as it helps them grow at a faster rate. Other algae lives in colonies on top of water and travel along with the water's curre..

How does glycogen function in living things?

Glycogen is less reduced, and thus less energy-rich, than fatty acids, which are used for more long-term energy storage. By comparison, glycogen is more easily broken down, and is therefore important in maintaining blood glucose levels between meals. This is especially important for the brain, which uses glucose for energy nearly to the point of exclusion. Glucose can also provide energy if there is a shortage of oxygen, allowing for energy production even when cells are in a state where they are using their fuel faster than the organs can take in air, an example of this being sprinting full t..

What is a river source?

Sources for rivers are typically found at higher elevations than downstream portions of the river. A river or stream that flows into a larger river may also be called a tributary. The main portion of the river often travels through a floodplain, leading out to the river's mouth, where the river deposits its water into a larger body, such as an ocean or a lake. The source of the river is the furthest point from the mouth of the river, also known as the estuary.

Why do seeds need to be dispersed in new places?

Seeds are dispersed to avoid the overcrowding of a plant species in one locality and to ensure the geographic spread of a plant across relatively large areas. There are several mechanisms used for seed dispersal. Light seeds, such as dandelion seeds, spread across wide areas as the wind blows. Some seeds, such as coconut seeds, are waterproof and can be carried by a current of water over long distances. Some seeds have hooks that allow them to attach themselves to the fur of animals passing by, and they are then dropped at a location far away from the parent plant.\nUsually, seeds are containe..

What is 300 grams in pounds?

One gram is the equivalent to 0.00220462 pounds. Therefore, when a weight is given in grams and needs to be converted into pounds, the weight in grams needs to be multiplied by 0.00220462. Using this conversion factor it is a very simple calculation to convert 300 grams to pounds. The result of multiplying 300 grams by 0.00220462 is 0.66 pounds. Many resources are available on the Internet to assist with making these types of unit conversions.

What is a continent?

Continents can be characterized by geography and by culture. For example, Europe and Asia are technically one landmass, but most geographers consider them to be two separate continents. Many islands are typically considered part of the nearest continent, although there are certain exceptions. Hawaii and New Zealand do not belong to a specific continent even though Hawaii is part of the United States.

For what is polypropylene used?

Polypropylene is a adaptable thermoplastic polymer that can be combined with other monomers to manufacture a wide variety of copolymers. The outstanding properties of polypropylene allow it to be used to replace alternative polymers, metals and glass. Polypropylene is a stiff material, has a low density and possesses good heat resistant properties. It also has great impact resistance and is able to be easily stretched when used in fiber and film applications

What is it called when someone is born with male and female organs?

According to the University of Rochester Medical Center, a person who has gonadal dysgenesis has underdeveloped gonads, meaning ovaries or testes, with internal reproductive organs that are usually female. The external genitalia in someone with this form of ambiguous genitalia tends to trend more on the female side, but it might be indistinguishable in some cases.\nWith pseudohermaphroditism, a person has questionable external sexual organs but the internal reproductive organs of only one sex. If a person has male gonads, the condition is termed as male pseudohermaphroditism. A person with fem..

What type of stress force produces reverse faults?

The main characteristic of a reverse fault it that a piece of rock from the plate is thrust up higher than the original level of the ground. This formation is also referred to as a scarp. In contrast, there are two other types of stress, both forming different types of faults.Divergent plate boundaries, which is when the land plates are moving away from each other, experience tensional stress. This type of stress produces normal faults. The rocks and landforms are stretched when tensional stress occurs. Since rocks cannot stretch indefinitely, they eventually break and form a fault. Since the ..
