100% (all living organisms of them have a rage of tolerance)
Answer:
after nutrients are absorbed during digestion,the excretory system removes faeces through the rectum. these work together to maintain oxygen homeostasis.
They were able to show how to produce the best plant with the right amount of light that the plant is exposed to.
They were also able to show how to draw blood plasma from the blood by studying its response to various stimuli.
Answer:
by phenotypically identifying plants unable (or with an altered ability) to synthesize auxins. This approach is called reverse genetics
Explanation:
Reverse genetics is a strategy widely used in molecular genetics aimed at analyzing the function of target genes by identifying defective phenotypes of one or more organisms following the disruption of the gene. In this case, a mutagenesis approach (i.e., irradiation with X-rays) was used to induce mutations in the gene/s involved in auxin production. Subsequently, the resulting mutant phenotypes, i.e., plants with an altered ability to synthesize auxin, can be used to reveal the biological function of individual (mutated) gene sequences.
