Yes! They get 50% of their genes from their mother & 50% from their father. However, if we’re talking about physical traits then no. Your mother MIGHT have more dominant genes whereas your father MIGHT have more recessive genes. Hope this helps!

In cells where telomerase is normally inactive, it can become active by accident and often, cancer will develop as a result. Can
vesna_86 [32]

Answer:

Cancer cells achieve proliferative immortality by activating or upregulating the normally silent human TERT gene (hTERT) that encodes telomerase, a protein with reverse transcriptase activity that complexes with other proteins and a functional RNA (encoded by hTR, also called hTERC) to make a ribonucleoprotein enzyme.

Explanation:

A rare cell that escapes crisis almost universally does so by reactivating telomerase and this cell can now become a cancer cell with limitless potential to divide. Almost all cancer cells have short telomeres and thus inhibitors of telomerase should drive such cancer cells into apoptotic cell death. Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell no longer can divide and becomes inactive or "senescent" or dies. This process is associated with aging, cancer, and a higher risk of death.

posledela

The geological process and interactions like earthquakes, volcanic eruption, cyclone etc, are responsible for the changes because these are very fast and sudden.

<u>Explanation: </u>

It is 4.5 billion years that <em>Earth has been formed and there have been changes since then</em>. Earthquakes, volcanic eruption, cyclone etc, are some of the geological process and interactions are the reasons for change in earth's surface. An earthquake usually split or divide the surface into many pieces in a very few seconds. While lava erupted from a volcano makes the land fertile by spreading around within minutes whereas a day of rainfall can lead to a flood in the neighborhoods and results in many losses.
