c) electron diffraction
Diffraction is the phenomenon of bending of wave around the corners of obstacles. It is only shown by waves. In electron diffraction, a beam of electrons get diffracted when it strike matter. Hence, it shows electron has wavelike properties.
d) A phenomenon that demonstrates that electron has wavelike properties is: a) the black body spectrum,...

B embryonic period of development. C ninth month of pregnancy. D None of the above.
33.6 A muon is a elementary particle whose properties are similar to those of an electron (a negative charge and a spin of 1/2) with to the exception of its mass. Because of this it is possible to replace a one or more electrons in an atom with muons. A muon is 207 times 5more massive than an electron (and so has mass 1.88 x 102 kg). If the electron in a hydrogen atom was replaced with a muon then...

2. The allele b gives Drosophila flies a black body, and bt gives brown, the wild-type phenotype. The allele wx of a separate gene gives waxy wings, and wx+ gives nonwaxy, the wild-type phenotype. The allele cn of a third gene gives cinnabar eyes, and cn* gives red, the wild-type phenotype. A female heterozygous for these three genes is testcrossed, and 1000 progeny are classified as follows: 5 wild type, 6 black waxy cinnabar, 69 waxy cinnabar, 67 black, 382...
