Osmosis Look at the concentration of sugar molecules on either side of the selectively permeable membrane. Sugar molecules cannot pass through this membrane, but water can.

Draw lines on each side of the tube to predict the water level once equilibrium is reached.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).

my answer is the prothallium.brainliest
