Answer:
A. There are fossils of extinct ancestors of horseshoe crabs and the species is still alive today.
Explanation:
C and D have more to do with how it can be a fossil. It is a living fossil because its ancestors have been found in fossils, yet it continues to live today.
Explanation:
when dogs breed the mother and father each randomly contribute one allele from each locus giving each allele 50% chance of being passed down to the pups. one of the alleles at each locus is dominant and determines the traits like coat color
C. ATP (Adenosine Triphosphate) has three phosphate groups attached. Each one of the groups occupies an extremely high energy bond (free energy that can do work). In muscle contraction, that high-energy bond is broken and the energy is released for muscle contraction. So when the bond is broken, you end up with ADP (Adenosine Dipohosphate) - broken down.
Every one color match up to light of a certain wavelength produced by the atom when an electron marks a changeover among permissible orbitals. Each color signifies a jump of the electron with resultant emission of photons of certain energy conforming to the vertical colored stripes. The scientist can assess these energies by means of einstein equation for the energy of a photon which is E = h. v where v is the frequency of the emitted photon that can be assessed by means of the wavelength and h is a constant. Then it can recreate the jumps and accordingly figure out the orbitals and perhaps the map of the structure of the atom.
