The answer is A it occurs before DNA is copied.
The right answer are all the three of them (1, 2 and 3).
Let's compare between a normal cell culture and a cancer cell culture:
- Normal or defined cultures: the cells only multiply during a limited number of degenerations (30 to 50 subcultures) then die: their life and their death is programmed. We then observe a decrease in their rate of proliferation, phase of senescence.
- Continuous culture or transformed or immortal lineages. The multiplication speed does not decrease (reproduction without limits, non-stop), which allows an indefinite number of subculture. The cells constituting these cultures lose the contact inhibition and grow in clusters or multilayer (multiple layers).
People use plants as fuel for transportation and heat. ... Fossil fuels store carbon, just as living trees and plants do. When burned, they release carbon dioxide into the air. The large and growing amounts of carbon dioxide in our atmosphere cause Earth's climate to warm.

Whales are fully aquatic mammals, with specialized adaptations to thrive in their environment. These adaptations, like blubber, allow these mammals to maintain their body temperatures in cold environments. They are part of the order that includes their closest relatives as even-toed, hoofed land dwelling mammals called Cetartiodactyla, as a suborder, Cetaceans. Balaenoptera is a genus of whales with around eight distinct species, including the fin whale and minke whale.
