How do RBC survive without nucleus? The red blood cells without nuclei, called reticulocytes, subsequently lose all other cellular organelles such as their mitochondria, Golgi apparatus and endoplasmic reticulum. The spleen acts as a reservoir of red blood cells, but this effect is somewhat limited in humans. Is RBC a living cell? rbcs are living […]
How does my body know how do you carry out the essential functions of life?
How does my body know how do you carry out the essential functions of life? Systems of specialized cells within organisms help them perform the essential functions of life, which involve chemical reactions that take place between different types of molecules, such as water, proteins, carbohydrates, lipids, and nucleic acids. All cells contain genetic information […]

Which are examples of water absorbing energy?
Which are examples of water absorbing energy? When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation. Water vapor (steam) mixes with the air and seems to disappear. A simple example is water boiling in a teapot and escaping into the air. What happens when the kinetic energy of […]

How many electrons can cytochrome c accept?
How many electrons can cytochrome c accept? one electron What happens if cytochrome c is inhibited? Cyanide, azide, and carbon monoxide all bind to cytochrome c oxidase, inhibiting the protein from functioning and leading to the chemical asphyxiation of cells. NO and CN− will compete with oxygen to bind at the site, reducing the rate […]
Is a magnitude 10 earthquake possible?
Is a magnitude 10 earthquake possible? No, earthquakes of magnitude 10 or larger cannot happen. The magnitude of an earthquake is related to the length of the fault on which it occurs. The largest earthquake ever recorded was a magnitude 9.5 on May 22, 1960 in Chile on a fault that is almost 1,000 miles […]
How did Brahe actually die?
How did Brahe actually die? The famed 16th century Danish astronomer and mathematician Tycho Brahe was long assumed to have died from poisoning.

What frequency means?
What frequency means? Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz (Hz) which is equal to one event per second. What happens to pitch when frequency […]
