What are some common Antarctic animals?

Antarctica boasts six species of penguins: adélies, emperors, gentoos, macaronis, rockhoppers and chinstraps. These penguins have dense, downy feathers coated with an oily substance that prevents water and cold from sinking down to the skin. A thick layer of fat protects them from the cold and keeps heat trapped close to the body. Emperor penguins, the largest of any species, grow up to 44 inches tall. The males take care of the eggs during the coldest weather, while the females feed. The small rockhopper penguins live on Antarctic islands.\nThe majority of seals live in Antarctica or on the ..

What is the function of the cerebrum?

The frontal lobe is located at the front of the brain, in the forehead area, and is responsible for movement, emotions, problem solving and judgment. The parietal lobe sits behind the frontal lobe on the back of the top portion of the brain. It deals with the senses of pressure, taste, temperature and pain. It is also responsible for movement in reaction to the different sensory stimuli. There are two temporal lobes located in the temple area on the sides of the brain. This lobe processes auditory stimuli and is responsible for language processes. The occipital lobe sits behind and below the p..

Is there a conversion chart of Celsius to Fahrenheit?

For a Celsius-to-Fahrenheit conversion chat which has more listed temperatures, one can refer to the AskNumbers.com Celsius-to-Fahrenheit conversion chart. This chart has the conversions listed from -24 degrees Celsius, up to 60 degrees Celsius, as well as some additional temperatures, such as 100 degrees Celsius, 200 degrees Celsius and 400 degrees Celsius.\nOne can use this formula to convert Celsius into Fahrenheit: °C x 9/5 + 32 = °F. To convert Fahrenheit into Celsius, the following formula is used: (°F - 32) x 5/9 = °C.

What causes rigor mortis in animals?

Over the next four to six hours, according to the Encyclopedia of Death and Dying, muscles continue to contract until endogenous and bacterial enzymes begin to break down the muscle fibers themselves. During the next six to 12 hours, the muscles continue to decompose, and the body grows cold and relaxes. Usually a decomposing body comes out of rigor mortis in 12 to 36 hours, depending on environmental conditions such as cold weather or extreme heat.\nAs the Encyclopedia of Death and Dying points out, many factors can affect the onset of rigor mortis, including species, age, gender and physical..

What is the formula to calculate force?

Contact forces exist when two objects physically touch one another; action-at-a-distance forces exist when two objects exert a push/pull on each other without touching. Gravitational force is an example of an action-at-a-distance force. Summing all force vectors an object experiences gives the direction it will move. The SI unit of force is the Newton (symbolized by N). One Newton is the force required to give one kilogram an acceleration of one meter per second per second.

What are the mRNA codons for phenylalanine?

According to notes on the SDSU website, most of the codons that code for the same amino acids (UUU and UUC for phenylalanine as an example) typically differ based on the third and last base. This is called the "wobble" site, because anticodons can also include the base "I" or inosine that matches with either A, U, or C in the mRNA codon.

What are the three muscles commonly used as sites for intramuscular injection?

Intramuscular injections are used in cases where other medicine delivery methods are either unsuitable or ineffective. These can include oral ingestion, intravenous injection (into the blood via a vein) and subcutaneous (where the medicine is injected into the epidermis of the patient just under the surface). Intramuscular is accepted as the fasted method of injection, states Healthline.

What is the texture of helium?

Elemental Matter describes helium as a "colorless, odorless, inert, gaseous element" with the atomic number two and the elemental symbol "He." Helium is used for many industrial purposes, including filling balloons, refrigeration, cryogenic research, deep sea diving and more. The element occurs naturally, both as a part of natural gases and in radioactive ores. It makes up approximately 23 percent of the universe's atmosphere.

What do cheetahs eat?

While best known for their world-record speed, cheetahs don't chase their prey down over long distances as they are not built for endurance. In the extreme heat of the savanna the cheetah can quickly overheat from exerting itself. Instead cheetahs slowly stalk animals within the cover of brush and then explode into a burst of speed. Generally they can overtake their prey quickly. Like other big cats, the fatal injury inflicted on their prey is a suffocating bite to the throat.\nBecause of their slight stature, the cheetah often has its kills taken by other predators like lions and hyenas...

What are some facts about the pituitary gland?

The pituitary gland, also known as the hypophysis cerebri, lies beneath the hypothalamus in the human brain, and is connected to the hypothalamus by a structure called the pituitary stalk. The pituitary gland was known even in the time of the ancient Greeks, although it was not until the 20th century that its many functions in the human body began to be understood.\nThese pituitary functions are possible due to the different types of cells that comprise it. In general, the pituitary gland secretes several types of hormones, each of which are responsible for different tasks within the body. Tro..
