Jordan's grandmother uses the juice from squeezed lemons to remove stains from his shirt. He hypothesizes that the juice is the

only part of the lemon that is effective at removing the stains, because it’s an acid. Which two steps would help Jordan determine whether his hypothesis is scientifically supported?
He should test the acidity of different parts of the lemon, including the juice, pulp, and skin.
He should conduct an opinion poll of residents to see if they agree with his hypothesis.
He should make identical stains on T-shirts and see whether different parts of the lemon will remove the stain.
He should find literature on housekeeping websites that support the use of lemon juice at removing stains.
He should compare lemon juice with other acidic juices to see if they all remove stains.

The correct answers option A and option E

The hypothesis that the juice of the lemon is the only pat of lemon that is capable of removing stains from the t-shirt is because the lemon juice is acidic in nature.

To test the validity of this hypothesis he should test the acidity of different parts of the lemon including the juice, pulp and skin of lemon.

He should also compare the lemon juice with other juices to know weather other juices are also helpful in removing stains from the t-shirt.

kirill115 [55]

Answer:

(A) Bioaccumulation

Explanation:

When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.

Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.

As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.

As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.

The cell model below shows 2 solutions separated by a selectively permeable membrane indicated by the red dashed line.
e-lub [12.9K]

So naturally, Water loves to be with water. This is just a common knowledge of biology. The side with the least amount of water will recognize that the opposing side has more water. Water molecules in Side A will essentially try and cross the selectively permeable membrane and go onto the crowded side. This will make the Cell in A become lysed and it will shrink. Your answer will be:


C. The Water level will increase on side B and decrease on Side A until concentrations are equalized.
