A benign tumour is generally not dangerous as they grow usually within a membrane in one space. They can however grow really big in a short space of time and can cause pressure on neighbouring blood vessels which can be dangerous.
Metastatic or malignant tumours are dangerous and cancerous. After they grow, some cells break off and travel in the bloodstream to a different area of the body (usually the main organs) and forms a secondary tumour there. This keeps happening until the cancer has spread to all of the body.

all membrane bound organelles are absent in prokaryotic cells. They only have a membrane, cytoplasm, DNA and ribosomes(and also some sort of a cytoskeleton that helps with division and cell shape)

Answer:
Both parents have the genes for yellow peas and green peas
Explanation:
If a plant has inherited one yellow peas gene and one green peas gene, the plant will produce yellow peas because (as you mentioned) yellow peas are dominant. that means the parents are heterozygous (Cc). If both parents have the gene versions Cc, then there is a 25% chance the offspring would get the gene version cc, coding for green peas.
Why do most cells in the human body divide infrequently? They have exited the cell cycle and entered G0. The free-energy change for the oxidation of glucose to CO2 and water is -686 kcal/mol, and the free-energy change for the reduction of NAD+ to NADH is +53 kcal/mol
