according to the theory of plate tectonics, the continents are embedded in lithospheric plates. as these plates move, they carry the continents with them. the ocean basins are part of lithospheric plates as well. identify the weakness in weneger's continental drift hypothesis.
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).
Flocculation is the process by which certain chemicals in the soil stabilize large soil aggregates.
