Answer:
In p53 pathways, 3 proteins which are mutate and cause cancer that proteins are:
1.BRCA2
2. p53 in Rb genes binds with deoxyribonucleic acid that stimulates another gene to produce a protein known as p21 that interacts with cdk2. When p21 is combined with cdk2 cell will not pass through to the next stage of cell division. This is Li-Fraumeni syndrome (when p53 causes cancer from parents to offspring)
3.BRCA1
The parent that transmits mutation in one of these genes has a 50% chance of inheriting the mutation. The effects of mutations in BRCA2 and BRCA1 are seen when the person's second copy of the gene is normal.
Producers rely on light because that is what they use to "produce" food. Consumers, however, also rely on light, because first of all they need to see, and second of all, the light fuels growth of producers, which in turn, when consumers eat the producers, promote growth of other consumers.
Great question :)
The stronger survived and the weaker passed on... Those with a weaker immune system had trouble with sickness and usually ended up passing on but those with strong immune systems were stronger and healthier and lived.
