Answer: Pauses
A pause is an interval of silence that vary in length. It is
not a source of problem in terms of vocal delivery, instead it can enhance the
message delivery, emphasize the information coming next is important and to give your audience time to
process what you have just said.
Moreover, the components of vocal delivery includes rate of
speech, volume, pitch, articulation, pronunciation, and fluency. In delivering
a speech, our voice is vital for it will help us engage and interest the
audience. In addition, vocal delivery aids in ensuring that our ideas are
communicated clearly to the audience.

I don't understand the sentences part... DNA is made up of nucleic acids. Bases adenine, guanine, thymine, and cytosine are then added in. They make different combinations, or sequences. Maybe these are the sentences you're talking about?
1. change
The natural selection is a process that occurs as a direct consequence of the living conditions in the environment. When the environment starts to change though, the organisms that live in it face a big challenge. They either have to change, adapt to the new conditions, and thus survive, or if they are not able to do so, to die out. This is the biggest evolutionary pressure for the organisms, and while some come out as winners from it, many others die out .
2. variation
In order for the process of natural selection to occur, the population needs to have some genetic variation. The environment is the ultimate push factor, but if the population doesn't have genetic variation in it, than the species will die out. The genetic variation is very important as in that way the individuals choose who will they mate with, in accordance with their traits, so that only the advantageous traits can be passed on to the next generation, so that it can be more competitive in the environment.
3. traits
The natural selection is a very simple process. The individuals of a population, when choosing a mate, look for the individuals that exhibit traits that are advantageous for survival. Mating with individuals with traits that are advantageous guarantees that the offspring will inherit those traits, thus it will have higher chances to survive. The individuals that do not have advantageous traits though will be avoided as mating partners, and that would rapidly lead to their decline and elimination from the gene pool, as they will not have any offspring to continue their line.
