There are many factors that affect plant growth, including the salts and minerals in their water supply. A farmer wants to find the right concentration of mineral solution to use with his sunflower crop. He places five sunflowers in a beaker of 1 M mineral solution, five sunflowers in a beaker of 0.5 M mineral solution, and five sunflowers in a beaker of 0.2 M mineral solution. a) Calculate the solute potential of a 0.5 M mineral solution at room temperature (25⁰C). A sample sunflower has a solute potential of -28 bars within its cells. (Note: i =ionization constant = 1.0) Determine the direction water will flow between the sunflower and its environment.

b) Once equilibrium is reached between sunflower and the environment, calculate the turgor pressure inside the plant cell.

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.

wild parsnip is a perennial plant which reproduces rapidly in areas which have no sign of agricultural activity such roadside or at no tillage open areas. it's considered invasive because it can inhibit the growth of another plant  and its reproduction is fast. there are several harmful effects of this invasive plant although its taproot is edible since it is a member of the carrot family. wild parsnips can cause skin blistering when in contact because of the chemicals it contains, second it inhibits the growth of other plants, it will restrict the growth of animals when eaten and lastly, it drives away natural pollinators like bees.
