Answer:
They would react the same as with the vinegar and hydrogen peroxide at room temperature.
Explanation:
In this experiment catalase acts as the catalyzing enzyme which decomposes hydrogen peroxide. All living things (be it frozen liver or a potato) consists of catalase. Such enzymes decompose one substance into another. Catalase enzyme helps in breaking down hydrogen peroxide into water and oxygen and also speed up the process of decomposition by providing and maintaining favorable situation. Therefore, irrespective of whether this catalase is found in the frozen liver or potato, they would react in the similar manner.
Hence, option A is correct
Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.
Cyanobacteria is the answer
Answer:
the troposphere directs the light towards us.
