¿which of the following organisms would be considered as heterotrophs?

a. my cousin juan who is a vegetarian

b. a seaweed

c. a banana tree

d. a coriander plant

a) Your cousin Juan.

Explanation:

All others can generate food from energy from the sun. Your cousin, unfortunately, can not, which is the definition of a heterotroph.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.

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.
