Answer:
D: They have restricted cell division.
Explanation:
Pre cancerous cells often act like cancer cells and will grow at abnormal rates but unlike cancer cells they are unable to invade other organs
Answer:
point mutation missense mutation silent mutation non sense mutation
Explanation:
point mutation it change one base of DNA in this case nucleotide substitution occur like sickle cell missense mutation in this case replacement of one nucleotide nonsense mutation cause the replacement of codon silent mutation does not change the sequence of protein because of new triplets codes for the same amino acid
Answer: FGF5 is produced in the outer root sheath of the hair follicle as well as perifollicular macrophages, with maximum expression occurring in the late anagen phase of the hair cycle. The receptor for FGF5, FGFR1, is largely expressed in the dermal papilla cells of the hair follicle.

Answer:
How do you work out energy transfer in a food chain?
Within the food chain energy can be passed and transferred from one organism to another. Whilst mammals get their energy sources from food – whether this be eating other animals or eating vegetation; plants get their energy from photosynthesis. Energy is passed between organisms through the food chain.
Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection.
