How does a paramecium eat?

The paramecium eats foods that include algae, bacteria and other protozoa or protists. In turn, the paramecium is preyed upon by other protists like amoebas, flatworms and water fleas.This organism is uni-cellular and reproduces through binary fission, or it splits in half. The inside of the paramecium consists of the fluid called protoplasm, nucleus and vacuoles. It also inhabits different water sources like ponds and rivers.

What are some freshwater herbivores?

Despite their preference for plant matter, most herbivorous freshwater fish benefit from some plant matter in their diet. Freshwater community fish should be fed once or twice daily with as much food as they can consume within a minute. Fresh treats can be offered to herbivores using a clip on the side of the tank to hold nori, lettuce, carrots, zucchini or sweet potato pieces.

How long does it take for muscles to atrophy?

Muscle atrophy comes in two forms: disuse and neurogenic muscle atrophy. Disuse atrophy is the result of a lack of physical exercise or activity. Muscles will appear thinner if they are not being used, explains The Free Resource. For example, astronauts experience muscle atrophy after a few days in zero gravity.\nNeurogenic atrophy, as defined by The Free Resource, is a more severe case of muscle wasting as the result of damage to the nerve or by disease. Neurogenic atrophy is associated with diseases such as Polio and Lou Gehrig's Disease. Once neurogenic atrophy takes hold, it is diffic..

What is the function of the left lung?

The lungs are respiratory organs that are found in the majority of air breathing animals. They are also found in a few species of fish and snails. Lungs are the principal way in which air breathing organisms transport oxygen from the atmosphere into their blood stream. Small cells known as alveoli comprise the right and left lung. These cells are the sites for gas exchange in the lungs and help the organism keep blood gas levels steady.

Why do leaves fall off trees?

During winter, less sunlight reaches the Earth, and the atmosphere becomes colder. As winter begins to approach, trees begin to prepare for the change. Tiny holes in leaves cause the tree to lose lots of water. During the winter, there is not enough water available to replace what the tree loses through the leaves. By sealing the holes where the leaves grow and shedding the leaves, the tree is able to use available water to survive the winter. If the leaves did not fall and the holes were not sealed during the winter, the tree would not be able to survive the winter season. By retaining water ..

What is manganese used for?

Mints use manganese to produce certain coins. According to Reference.com, the United States used the metal in nickels from 1942 to 1954 and began using it in one dollar coins in 2000. In Europe, both 1 and 2 Euro coins contain manganese.\nManganese(IV) oxide is the black material found in the original type of dry cell battery. In newer alkaline batteries, however, the electrolyte responsible for accepting electrons from the zinc is a different chemical.\nAccording to About.com, in the glass industry, manganese dioxide removes the green color caused by iron impurities in the silica. The metal a..

What is the measurement for sunshine?

Every time the Sun shines on the device, its rays leave a trace on the card in the form of a burn. By gauging the length of the burn, it’s possible to determine the amount of sunshine. When compared to the readings provided by modern electronic sensors, the burn marks on the cards can provide information regarding the solar radiation and cloud thickness in addition to the sunshine duration.

What are some common ionic compounds that are used in everyday life?

Another common ionic compound is paper. This compound is composed of nitrogen, carbon and oxygen. Water is also an ionic compound, as well as drinking water, which is expressed as nitrogen and oxygen. Plastic is another example of an ionic compound that is made up of carbon and nitrogen. Some other examples are wine, glass, fireworks and dairy. All of the above are considered to be polyatomic ions because they are composed of two or more covalently bonded atoms. The ion acts as though it were actually only a single atom.

Can an object be accelerating if its speed is zero?

Two examples of objects accelerating with zero speed are a ball thrown into the air at its highest point and a pendulum at its highest point. In the case of the ball, it is under constant negative acceleration due to the force of gravity. Its vertical motion initially travels upwards, slows down, stops for an instant, then starts falling back towards the Earth. At the point where it stops for an instant, it has zero speed and negative acceleration. Similarly, in the case of the pendulum, the constant force of gravity slows its upward momentum, makes it stop for an instant, then causes it to fa..

What are the harmful effect of fungi?

Fungi is the cause of mold in homes and buildings. Indoor mold typically develops in areas where water is present, and can cause serious damage to homes and buildings. Mold remediation is often time-consuming and costly, and may require significant repairs to structures, particularly after floods.\nExposure to indoor mold can cause illnesses that range from mild symptoms, such as irritation of the respiratory system, but other types of fungi can cause serious disease in humans and animals. For instance, those with compromised immune systems may develop a life-threatening illness after being ex..
