Explain what would happen if animals lose body parts? All organisms have unlimited amount of time where they can regenerate new body parts.
All animals and plants go through mitosis to make any new needed body parts.

Certain organisms can reproduce new body parts such as starfish and amphibians, while other do not make new ones.

There are no species of plants and animals that can acquire new body parts once the original ones are lost.

You are studying several alleles of an e. coli helicase gene. one allele, called rsr, confers resistance to rs2014, an antibiotic that works by inhibiting helicase activity. bacteria with the rss allele are sensitive to rs2014. another allele, called ts-, produces a temperature sensitive mutation of the helicase. in bacteria with the ts- allele, helicase is inactivated at 42 °c but functions normally at 37 °c. helicase functions normally at both temperatures in bacteria with the ts allele. you obtain the following data while testing four strains of e. coli at different temperatures and doses of rs2014. each number represents the percentage of maximal dna synthesis. based on this data, assign the appropriate genotype to strains a–d in the spaces provided
