Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
Based on the investigation, the inference that can be made about the result is that catalase activity increases with warm temperature.
The liver usually contains an enzyme known as catalase that is capable of breaking down hydrogen peroxide into water and oxygen gas. The bubbles observed in the beaker during the investigation represent the oxygen being evolved from the breakdown of the hydrogen peroxide by the catalase in the liver sample.
At room temperature, a moderate number of oxygen bubbles were observed. The number of bubbles increased with increased temperature as a result of placing the beaker in a warm water bath. At a lower temperature brought by placing the beaker in an ice water bath, no bubbles were observed.
Thus, we can effectively conclude that the activities of the catalase enzyme in the liver increased with a moderately increased temperature.

Answer:
B
Explanation:
You can't change your DNA as far as I know and if you inherit exact copies of DNA from your parents that means you're a clone which human clones don't exist. You inherit genes from both your mother and father i.e you have blue eyes like your dad and brown hair like your mom.
Answer:
What is the link between the light reactions and the Calvin cycle during photosynthesis?
Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH. The Calvin cycle, which takes place in the stroma, uses energy derived from these compounds to make GA3P from CO2
