Mendel was the first person to succeed in predicting how traits are inherited from generation to generation.
When glucose is high, cAMP is low; CAP does not bind the lac operator, and RNA polymerase does not bind the lac promoter. CAP is only active when glucose levels are low, which means the cAMP levels are high, and therefore the lac operon can only be transcribed at high rate when glucose is absent. The importance of this is that the bacteria only turns on the lac operon and start using lactose only after they have used up all the preferred energy source which is glucose.
Genetic relationships, gene expression patterns, microRNAs, and active hormonal controls all contribute to the genetic foundation of leaf form. organelle 1 is large vacuole, 2nd organelle is mitochondria, organelle 3 is nucleus and organelle 4 is cell wall.
The size of the cell and the number of cells determine the size of the leaf. Plant hormones, growth-regulating factors (GRFs), TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP), WUSCHEL RELATED HOMEOBOX (WOX), and other regulatory factors control cell expansion and differentiation [3,4].
Rough E.R. makes and transports substances through the cell and Smooth E.R. does not have ribosomes; Ribosome make protein for the cell.

Answer is hypertonic.
The ability of an extracellular solution to make water move into or out of a cell by osmosis is known as its tonicity. Tonicity is concern for all living things, especially in in organisms lacking cell wall, <em>Paramecium</em> is one such protozoan. It has specialized structures called contractile vacuoles. A contractile vacuole collects excess water from the cell and release it out, keeping the cell from lysing as it takes on water from extracellular environment which hypotonic (a lower osmolarity than the cell’s cytoplasm) as compared to hypertonic environment inside <em>Paramecium</em>.
