The scientist should do the following to make sure that their scientific investigation is replicable is by having to have their studies, researches and experiments to be written down as this will serve as a basis and a way of having to have a solid proof of having the investigation or experiment to be conducted again or to be replicable.
Answer:
Explanation:
Bone, or osseous tissue, is a connective tissue that constitutes the endoskeleton. It contains specialized cells and a matrix of mineral salts and collagen fibers.
The mineral salts primarily include hydroxyapatite, a mineral formed from calcium phosphate. Calcification is the process of deposition of mineral salts on the collagen fiber matrix that crystallizes and hardens the tissue. The process of calcification only occurs in the presence of collagen fibers.
The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 19.16).
Wavelength have an indirect relationship with frequency. Since gamma rays have the shortest wavelength, then they have the highest frequency. As the wavelength shortens, the frequency heightens.
Radio waves for example, have the longest wavelength, so it is expected that they have lowest frequencies.
Answer: Mercury-194 is an unstable isotope and hence is radioactive.
Explanation: Mercury-194 is an isotope of mercury, having formula
Number of protons in this isotope = 80
Number of neutrons in this isotope = 114
This isotope is radioactive in nature and under decay process by Electron Capture.
Electron capture reactions are the reactions in which a proton in a nucleus absorbs an electron and convert it into neutron. The resulting nucleus will have a decreased atomic number and same atomic mass.
Reaction for electron capture of mercury-194 follows:
