Answer:
D: a trait with a dominant and recessive allele!
d. The farther an electron is from the nucleus, the greater its energy.
Explanation:
The energy of an electron relates with the distance from the nucleus in that the farther an electron is from the nucleus, the greater its energy.
The nucleus of an atom is where the protons and neutrons are located.
Electrons orbits round the nucleus in certain permissible energy levels.
- According to quantum mechanics and the Bohr's model of the atom, the energy levels of orbital electron is quantized.
- The ground state is the state with the lowest energy and close to the nucleus.
- The outer most electrons are located in the highest energy levels
- Therefore, the farther an electrons is from the nucleus, the greater its energy

Answer:
C. Oxygen supply
Explanation:
Autotrophs make their own food with carbon dioxide and create oxygen as a byproduct. Heterotrophs need oxygen to create energy and create carbon dioxide as a byproduct. Therefore, if there are no autotrophs, the carbon dioxide in the air won’t be able to be used to turn to oxygen, which heterotrophs need. The heterotrophs will use up all of the oxygen in the air, leaving lots of carbon dioxide behind. This is why we need plants and trees! Thus, the answer is C.
