FILL IN THE BLANK (pls help) When a vibrating object is moving **(toward, away from, alongside)** an observer, the measured frequency of the vibrations will be lower than if the object and observer are both stationary. If the vibrating object is moving **(toward, away from, alongside)** an observer, the measured frequency of the vibrations will be higher than the actual rate of vibration of the object. When a star is moving towards an observer on Earth, the light spectrum of the star will appear **(redshifted, blueshifted, the same)** compared to the light spectrum of the sun, which is considered to be in Earth's frame of reference.

This is for physics

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
