The oldest fossils present at the bottom of rock layer whereas the youngest fossils are present in the top layer.
<h2>Rock layers from oldest to youngest</h2>
The rock layers that is located farthest from the ground surface are considered as the oldest rock layers and rock layers that are closest to the ground surface are considered as the youngest. A fossil is the remains or traces of plants and animals that lived long ago.
<h3>Presence of fossil</h3>
Those fossils which are present at the bottom of the rock layers are considered as the oldest fossil followed by the upper layer's fossil and so on. The fossils present at the top layer are the youngest fossils so we can conclude that oldest fossils present at the bottom of rock layer whereas the youngest fossils are present in the top layer.

PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.
The smallest component that makes up a chemical element is an atom. Atoms that are neutral or ionized are the building blocks of all solids, liquids, gases, and plasma. A normal atom is 100 picometers across, which is incredibly small.
Protons, which have a positive charge, make up the majority of it, while neutrons, which have no charge, form the remainder. All regular, naturally occurring atoms have protons, neutrons, and electrons that orbit them because they are heavy particles.
A sample's mass in grams should be divided by the periodic table's amu atomic mass, and the result should be multiplied by 6.02 x 1023, or Avogadro's number, to determine how many atoms are there. So, PbSO4 has 1 atom of Pb, 1 atom of S, and 4 atoms of O. So, in total it has 6 atoms.

Answer:
Selective breeding.
Explanation:
Both are fairly long processes, however, the measurement for this is not just the duration to obtain the target, but also the exact target obtained. In natural selection, the duration may be faster than selective breeding in obtaining a change, but the determined change may not be the one that is sought out for. It may have a small chance, but it is not guaranteed. In selective breeding, on the other hand, the destination is determined, and all steps work towards the objective. So in a sense, selective breeding has the greater percentage chance of being the shorter process.

Hey!
First, we must know the definition of a "qualitative observation." The definition of a qualitative observation is something that can be observed with our senses. Such senses include touch, taste, sight, smell, and hearing. It wouldn't directly involve measurements, weight, and exact sizes since we cannot know this from our senses alone.
Now, we can solve this problem with the process of elimination to find which option is the best fit for the definition.
We'll start with option one.
<em>Option One :</em>
<span>An observation in which the length, volume, or weight of something is measured.
</span>According to the definition, this statement cannot be the answer because it states it needs the length, volume, or weight of something is measured. A qua<span>litative observation does not need these things.
<em>This option is INCORRECT.</em>
Let's look at option two.
<em>Option Two :</em>
</span><span>An observation that depends on an objective measurement rather than a subjective assessment.
Again, this statement says that it depends on an objective measurement, which is something a qua</span><span>litative observation do not need.
<em>This option is INCORRECT.</em>
Moving on to option three.
<em>Option Three :</em>
</span><span>An observation in which something is counted.
According to the definition of a </span>qualitative observation, a <span>qualitative observation is going to require more than just counting an object. So, this cannot be the correct answer.
<em>This option is INCORRECT.</em>
With all of the options gone, this must mean that the last answer is the correct answer. But just to be 110% sure we'll take a look at the option.
<em>Option Four :</em>
</span><span>An observation in which the appearance of something is described using descriptive language.
According to the definition, this option is the correct option. It provides a close enough definition that matches a </span><span>qualitative observation. It states the checking the appearance of something in descriptive language.
<em>This is CORRECT.</em>
So,the answer to this question is...
<em>The option that provides a good definition for a </em></span><span><em>qualitative observation is</em> option D.
Hope this helps!
