A homogeneous mixture<span> has the same uniform appearance and composition throughout. Many homogeneous </span>mixtures<span> are commonly referred to as </span>solutions<span>. A </span>heterogeneous mixture <span>consists of visibly </span>different<span> substances or phases. The three phases or states of matter are gas, liquid, and solid.

The<span> pros of using GMO are that
they result in higher yields than natural food crops hence able to feed a growing
human population on earth. They are also able to withstand crop diseases and
pests hence improved yields. </span>
The cons of transgenic
plants contribute to antibiotic resistance especially due to the use of antibiotic
resistance genes in recombination genes. Another is the environmental impact.
GMO may result in uncontrolled gene transfer to natural crops in the environment
hence created challenges such as super-weeds.

d) Ne
Explanation:
This electron configuration for the atom in its excited state violates the Aufbau principle or rule like we have above.
Aufbau principle states "that in the ground state of an atom or ion, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels."
We however can know and identify which element is in the excited state by knowing the sum of the electron that spread across the orbital and matching it up with the atomic number of the element in the periodic table.
It's genre. Look for something either on a final or starting page near the cover, and check to look if it's non fiction, or anything else that could prove it as reliable.
