Professional presentations is about making an impact on the audience. Your slides of the presentation should look perfect and should arrange in a sequence.
What makes a good professional presentation?
If we want to design our professional presentation in a beautiful manner then we have to write introduction first, then on the second number we should write body, and in last we should to write conclusion. Our introduction needs to briefly sum up that the audience don't get bored, we need to talk about only what is going on in presentation. Tell the audience about advantages, disadvantages as well as about the uses.
So we can conclude that: Professional presentations is about making an impact on the audience. Your slides of the presentation should look perfect and should arrange in a sequence.

It is true that telomerase activity declines with old age which explains why cells lose their ability to divide after many replications.
Telomeres are DNA–protein complexes found at the ends of each chromosome they contain repetitive sequences of DNA. Telomeres protect the genome from nucleic bases degradation, unnecessary recombination, repair, and prevent the fusion of chromosomes. Telomeres, therefore, play a vital role in preserving the information in our genome.
Telomeres shorten with every consecutive DNA replication cycle limiting the number of cell divisions a cell can undergo, Telomeres act as a tumor suppressor by halting the replication of cells which contains several mutations after many division cycles.

The geological history of Earth follows the major events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left over from the formation of the Sun, which also created the rest of the Solar System.
Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as a result of the impact of a planetoid with the Earth. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
As the surface continually reshaped itself over hundreds of millions of years, continents formed and broke apart. They migrated across the surface, occasionally combining to form a supercontinent. Roughly 750 million years ago, the earliest-known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia, 600 to 540 million years ago, then finally Pangaea, which broke apart 200 million years ago.
The present pattern of ice ages began about 40 million years ago, then intensified at the end of the Pliocene. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years. The last glacial period of the current ice age ended about 10,000 years ago
