The ability for cancer cells to divide
indefinitely is made possible because Cancer cells rebuild their telomeres
after every cell division.
At each end of the chromosome, there is a
region of repetitive nucleotide
sequences, this is called telomere and when a cell begins to become cancerous,
it divides more often. Telomeres are crucial for the survival of cancer
cells and they are
maintained by an enzyme called telomerase.

Answer:
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. ... The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
