: Use the following words to fill in the blanks: transcription, dairy products, enzymes, proteins, repressor, rna polymerase, lactose intolerant, lactase, operator, ecoli, transcribe, bases, repressor, operator

An example of prokaryotic gene expression is the lac operon. When a person is 1), they do not produce the enzyme 2), which aids in the digestion of lactose, the sugar found in 3). If a person who is lactose intolerant eats or drinks a dairy product, lactose travels down the digestive tract into the large intestine, where the genes in the bacteria, 4) , are turned on to create the 5) / 6) needed to digest the lactose. In E. Coli, when lactose is present, it acts as an inducer and binds to the 7) protein, keeping it from attaching to the 8). 9) then is able to attach to and 10) the E. Coli gene by matching up the 11). When lactose is NOT present, the 12) protein binds to the 13 and transcription is blocked. This is an example of gene expression (production of proteins) being controlled at 14).

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
