The macronucleus is the larger elipse-shaped nucleus and takes care of
functions like respiration and digestion. In contrast to this, the
smaller micronucleus is only involved in cell division or reproduction.
C. decomposer
C. from other organisms
Answer:
To transfer the encoded information in DNA to the ribosomes in the cytoplasm.
Chlorofluorocarbons
(CFCs) chemicals contain carbon, chlorine and fluorine and is t so expensive at
the same time it’s not flammable, the reason why it is mainly used in business
such as refrigerators and plastics. However, these chemicals destroys our
stratosphere, the second layer of the Earth’s atmosphere and protects us by
blocking the ultraviolet radiation (UV Light). This type of radiation can seep
through organisms skins and can leave destructive effects on DNA molecules
which will also cause skin cancer.

Answer:
All of the choices are correct.
Explanation:
- When a substance emits light which is not a result of heat, then such a spontaneous emission fo light is known as luminescence.
- Several chemical reactions or electrical energy can lead to the production of luminescence by organisms.
- The enzyme that is responsible for the production of bioluminescence by the organism is luciferase and it is capable of producing luminescence by catalyzing oxido-reductive processes.
- Luminescence is also produced in bacteria, and it is often controlled by the process of quorum sensing.
