Answer:
Homolog genes with sequence identity often exhibit differences in length associated with size variations in the intronic sequences
Explanation:
In eukaryotic organisms, genes are composed by 1- coding sequences (i.e., exons) that are transcribed into precursor mRNAs, and 2-noncoding regions (or introns), which are not transcribed but contain sequences involved in the control of gene expression
The correct answer is As technological advancements are made, the cell theory may change.
The technological advancement can lead to new discoveries, which may or may not support the existing cell theory. There are many evidences present in the past, in which the technological advancement has proved the theory incorrect or needs to be modified. So, every theory can change over time due to the new discoveries and the researches.
Answer:Among the oldest methods of preservation are drying, refrigeration, and fermentation. Modern methods include canning, pasteurization, freezing, irradiation, and the addition of chemicals. Advances in packaging materials have played an important role in modern food preservation.
