Answer:
through natural selection
Explanation:
Natural selection is the driving mechanism of the evolution of species. Organisms can survive more in an environment if they are capable to adapt the changing environmental conditions. After surviving they are also able to pass their modified trait into their future generations (evolution).
Helpful variations accumulate through natural selection, as the organisms that are better adapted to their environment reproduce offspring with the same variations.
Answer:
b
Explanation:
Atom is the smallest particle of an element
Answer:
A₅B₄
Explanation:
Since we have one atom of element A at the center of each face of the unit cell, since the unit cell is a cubic cell, we have 6 faces. Since the atom on the face of the unit cell is shared with another cell, we have half of it in the unit cell is shared So, the number of atoms per face is 1/2 atom/face × 6 faces = 4 atoms on the faces of the unit cell.
Also, we have 1 atom at each corner of the cubic unit cell. Since there are 8 corner in the cubic unit cell. Also, each atom at the corner is shared with 8 unit cells, so we have 1/8 atom per corner. So, the number of atoms per unit cell is 1/8 atom/corner × 8 corners = 1 atoms at the corners of the unit cell.
So, in total we have 4 + 1 = 5 atoms of element A in the unit cell.
Also, there are 4 atoms of element B in the unit cell.
So, the ratio of atoms of element A to element B is 5 : 4.
A:B = 5:4
So, the empirical formula of the compound containing elements A and B is A₅B₄
According to the image in this question, the type of reaction shown is that of fission because nuclei are being split into smaller and smaller places.
<h3>What is nuclear fission?</h3>
Nuclear fission in radioactivity is the process whereby the nuclei of atoms split into smaller particles.
In the above diagram, an atom of uranium is labeled and its nucleus is shown to split into smaller particles in succession.
Therefore, the reaction exemplifies a nuclear fission because nuclei are being split into smaller and smaller places.

Each mole of N₂ generates 2 moles of Li₃N. Thus,
0.08 moles of Li₃N will require:
0.08 / 2
= 0.04 moles of N₂
The second option is correct.
