Start off with 2,500 plants of which 50 % have medium - tip leaves , 25 % have wide - tip leaves , and 25 % have drip - tip leaves . Each circle in your simulation will represent 125 organisms . Calculate how many circles you need for each trait , and then create your simulation . Be sure to include a key that states the color coding for each trait

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.

all matter is made up of atoms

in any element all atoms are the same

elements in a compound are always in a constant ratio: apex

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.
