ch Ce... 12. In cancerous tissue the % of cells dividing is MUCH higher than healthy tissue. One cause of this is an issue with the checkpoints in the cell cycle. Why would having a checkpoint in the cell cycle not working potentially lead to cancerous cells/tissue? ​

I would answer but it is to blurry can u take another pic

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.

It is used to during sexual reproduction between humans
