They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose.
Answer:
Time in hours
Explanation:
Given
Decimal reduction time for endospores of Bacillus cereus in milk minutes
Temperature at which bacillus endospores are reduced °C
Population of endospores to be reduced
Targeted population of endospores
So the total time taken to reduce population of 1015 endospores to 1 endospore is equal to
minutes
Time in hours
Answer:
Both follow duplication of chromosomes. Both include breakdown of the nuclear membrane. Both require spindle fibers to move chromosomes around.
Explanation:
Answer:
The correct answer is C. epigenetics
Explanation:
Epigenetics is the study of change in the phenotype that occurs not due to change in the DNA sequence but because of gene expression modification. So here we study the changes that occurred in phenotype, not in genotype.
DNA methylation, histone modification, etc can be responsible for the epigenetic changes in an organism. In DNA methylation, a methyl group or methyl cap is added to the DNA segment which prevents the expression of some genes.
The skin cell, brain cell, and muscle cells have the same DNA but due to epigenetic change(change in expression), they look different. So the correct answer is C. epigenetics.
