At your lab station, you put 30 mL of hydrogen peroxide into three separate beakers and add 2 grams of ground up liver to each o

ne. You place one beaker in a warm water bath and one beaker in an ice water bath. One beaker is kept at room temperature. Large numbers of bubbles are observed forming in the beaker with the warm water, a moderate number in the room temperature beaker, but almost no bubbles are produced in the cold version of the experiment.Based on the investigation above, what inference can be made about the results?

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.

During dna replication two extra guanine bases are added to the dna. what type of mutation is this
Alex777 [14]
Based on the above information, the mutation type is frameshift mutation. 


It is a genetic mutation caused by indels of various nucleotides in a DNA succession that is not detachable by three. The additions and erasures cause an adjustment in the length of a quality, which causes a movement in the codon perusing outline. A frameshift mutation happens when a protein is radically modified as a result of an addition or an erasure. Tay-Sachs illness is a human issue caused by a frameshift change.

What is a radioactive isotope?
saul85 [17]

B. An atom whose nucleus is unstable and emits particles and and energy. This is a Radioactive isotope.

The atomic nuclei of constituent atoms of the same element include the same number of protons but different numbers of neutrons. Radio isotopes are an element's radioactive isotopes. They can alternatively be described as atoms with an excess of energy in their nucleus or atoms with an unstable ratio of neutrons to protons. A radioisotope's unstable nucleus can form either spontaneously or as a result of a deliberate alteration of the atom. Radioisotope production can occur using either a cyclotron or a nuclear reactor. Molybdenum-99, which has a high neutron content, can be produced most effectively in nuclear reactors, whereas fluorine-18, which has a high proton content, can be produced most effectively in cyclotrons. Uranium is the most well-known illustration of a radioisotope that is found naturally. Uranium-238 constitutes all naturally occurring uranium with the exception of 0.7%.
