The average for male adults is about 60% and an female adult is around 50% depending on weight , age , and height
Answer:
Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.
Explanation:
Answer is: <span>5. one pair of electrons and two lone electrons.
Electron configuration for carbon: </span>₆C 1s² 2s² 2p².
Valence electrons are in 2s and 2p orbitals. There is one pair of electrons in 2s orbital and two lone electrons in 2p orbital with the same electron spin. Carbon is in group 14 of periodic table group.
Answer:
B. particles in an object move faster
Explanation:
At higher temperatures, particles in an object moves faster.
Temperature is the degree of hotness or coldness of a body.
- At higher temperature, the substance is very hot.
- Temperature is related to the heat energy content of a body
- As the temperature increases, the average kinetic energy of the particles of system increases more and more.
- This is in compliance with the kinetic molecular theory of matter.
- Therefore, at higher temperatures, particles in an object move faster.
Answer:
The answer is false, because in order to decompose organic matter, decomposers take CO2 from the environment and thus generate organic decomposition.
This sentence can be misinterpreted and be confused since the explanation explains the method of CO2 release from the decomposers, but in a non-polluting way.
Explanation:
Decomposing organisms are responsible for an increase in CO2 since they transform the complex molecules of organic matter into simple inorganic compounds such as carbon dioxide, water and mineral sales that return to the substrate to be used as nutrients by producers.
Although it is important to keep in mind that this is insignificant in comparison to human contamination since CO2 is mostly released to the earth and used as NATURAL FERTILIZER and very little to the air or the gaseous environment.
