Answer:
1 similarity between humans and bacteria, is that they both contain DNA.
Tumor cells are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells.
Operons are the functional units of transcription and genetic regulation. These are found in bacteria and their viruses where genes coding for functionally related proteins are grouped along the DNA.
The two types of operons are- inducible and repressible.
They regulate the genes as in negative inducible operons, a regulatory repressor protein is bound to the operator. It prevents the transcription of the genes on the operon. If positive inducer is present, it binds to the repressor and changes its conformation so it is unable to bind to the operator.
A unique feature of the nucleus is that it disassembles and re-forms each time mostcells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.

The correct answer for this question is (D) It can proceed in the dark.
Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a <u>light-independent reaction so also called as dark reaction.</u>
The Calvin cycle proceeds in three stages:
1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate
2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH
3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.
