TP5 1. Diagram above shows a whale stranded on the beach.
Based on your knowledge about the support system of whates can the whale return to the sea
on its own? Justify your answer. (5 marks)

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

the animal that would be cutest if scaled down to the size of a cat? elephant

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.

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
