At what age are people most physically active?
At what age are people most physically active? Age The age group 18 to 44 was the most likely to exercise. Of those individuals age 18 to 44, 59.7 percent reported exercising at least three times a week for half an hour or more. This compares with 53.5 percent and 46.7 percent, respectively, for the […]
What happens when entropy decreases?
What happens when entropy decreases? The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease. Entropy is very different from energy. Entropy is not conserved but increases in all real processes. What causes […]
Is the relationship between frequency and wavelength direct?
Is the relationship between frequency and wavelength direct? Wavelength (typically measured in nanometers) is the distance between two points in a wave. Frequency and wavelength have both direct and inverse relationships. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. Is frequency and energy directly […]
Is ATM a volume?
Which disease is the result of somatic mutation?
Which disease is the result of somatic mutation? Somatic mutations can give rise to cancer (9), as well as noncancerous diseases. Noncancerous somatic mutations that occur during development may affect cell proliferation, as would be the case in cancer, or they may simply alter cellular function without causing a proliferative effect. What causes somatic mutation? […]
Where are valence electrons located and why are they important?
Where are valence electrons located and why are they important? The electrons that occupy the outer most shell of an atom are called valence electrons. They are important because they determine how an atom will react. By writing an electron configuration, You’ll be able to see how many electrons occupy the highest energy level. Why […]
Is Lodestone a permanent magnet?
Is Lodestone a permanent magnet? The lodestone is an extremely rare form of the mineral magnetite (Fe3O4) that occurs naturally as a permanent magnet. What type of magnet is a fridge magnet? Refrigerator magnets are usually made from materials that are ferrimagnetic. Similarly, refrigerator magnets are made of a material that is permanently magnetized – […]
What do prokaryotes and eukaryotes have in common?
What do prokaryotes and eukaryotes have in common? Both prokaryotic and eukaryotic cells have structures in common. All cells have a plasma membrane, ribosomes, cytoplasm, and DNA. Ribosomes are the non-membrane bound organelles where proteins are made, a process called protein synthesis. Do prokaryotic and eukaryotic cells have Golgi bodies? Eukaryotic cells contain a membrane-bound […]
Are darkroom chemicals dangerous?
Are darkroom chemicals dangerous? The majority of chemicals used in the black and white darkroom are classified in the range of non-toxic to slightly toxic. However, black and white developers can be toxic, especially if when ingested or inhaled or when in contact with bare skin. Are the chemicals used to develop film Toxic? Most […]
