How does bacteria make food?

These types of autotrophs, called photoautotrophs, use glucose as their source of energy.\nIn the process of chemosynthesis, autotrophs use energy from inorganic chemical reactions, instead of sunlight to make their own food. Known as chemoautotrophs, they derive energy from inorganic sources, such as ferrous iron, hydrogen sulfide and ammonia to use in chemosynthesis.\nThese types of autotrophs are rare and live in harsh environments. For example, chemoautotrophs that live close to hydrothermal vents deep below the ocean use hydrogen sulfide and other minerals the vent emits to make their own..

What are the three greatest factors that cause erosion?

Water erodes the earth through rainfall and runoff. Heavy rainfall breaks down the soil surface and disperses the material.\nWind can cause major losses of soil. Depending on the particle size and wind strength, soil can be moved through suspension, saltation and surface creep.\nTillage erosion occurs when soil is redistributed through agricultural practices or gravity. Soil moves down the slope, resulting in soil loss on the upper-slope locations.

What are the four things that forces can cause objects to do?

Conversely, an object's acceleration is inversely proportional to its mass. When one doubles the mass of an object, its acceleration is reduced by half, assuming the force applied remains constant.\nIn terms of shape changes caused by force, objects are divided into two types: elastic and plastic. Elastic objects return to their original shape after a force has been applied. Plastic objects, on the other hand, change shape and remain deformed after force is applied.

What is the rainiest city in the USA?

It's a common misconception that Seattle, Washington, is the rainiest city in the United States, when, in fact, the top 10 rainiest cities are all located in the eastern half of the states. Cities throughout Florida, Louisiana and Texas also experience some of the highest amounts of rainfall across the country. These states, including Alabama, all sit on the Gulf of Mexico and receive the heaviest amounts of rainfall between June and November. This is due to the warm waters around the equator that are very active during hurricane season.

What are the planets' rank by size?

The largest planet, Jupiter, is 1,120 percent the size of the Earth, with a radius of 43,441 miles compared to the Earth's radius of 3,959 miles. Saturn is 945 percent larger than Earth and has a radius of 36,184 miles. Uranus has a radius of 15,759 miles, Neptune has a radius of 15,299 miles, Venus has a radius of 3,761 miles, Mars has a radius of 2,460 miles and Mercury has a radius of 1,516 miles.

Are minerals organic?

Organic minerals are obtained through food, vitamins and supplements. Water is the primary source of inorganic minerals such as calcium carbonate. These minerals are good for plants, but they can cause conditions such as gallstones, arthritis and joint pain in humans. Inorganic minerals can be removed from water through filtration systems, including distillation and reverse osmosis.

What is genetic diversity?

Over time, populations of species retain some common features while losing others. This phenomenon, called natural selection, promotes survival of the strongest genes. These genes give organisms better chances of surviving in specific habitats, reproducing and enjoying longer lives. This type of genetic variation produces differences in genes over an extended period of time, although genetic diversity occurs in the short-term too, altering the traits and characteristics between parents and offspring. Genetic variation occurs naturally, but humans create differences in genes too. This controlle..

How does someone turn a light bulb on with a battery?

Contacts differ from bulb to bulb. Some are prongs extending from the bulb's base below the threading while others include a threaded contact and another, smaller one without threads extending from the base. Spring contacts, found in most flashlights, are a good connector.Good combinations of bulbs and batteries according to capacity include:3V flashlight bulbs and three D batteries in sequence.12V interior car bulbs and eight battery cells in sequence.Regular 120V household bulbs require matching batteries which can be hard to find.Batteries improperly matched to light bulbs will not lig..

What is the definition of solar energy?

Active solar energy involves equipment or an action to convert solar energy into a useful form. One example of active solar energy is the use of solar cells to convert energy from the sun into electrical energy that can be used in the home.\nPassive solar energy does not require any specific action or equipment. An example of passive solar energy is strategically placing windows in a home to allow sunlight to enter and provide heat.

How long does short-term memory last?

An example of information that is too large for the average person's short-term memory is a long phone number. Repeating the number every few seconds resets the short-term memory clock, making the number memorable for a longer span of time. Information that is used or repeated on a regular basis is more likely to be stored in the long-term memory.
