Answer:

the sample contains starch and starch is stored in ground tissue.

Explanation:

It should be understood that Iodine solution is used to test leaves for the presence of starch. This will show a blue-black color, which means the presence of starch.

This process can simply be demonstrated by simply following these steps.

* Take two potted plants of the same kind.

* Keep one in the dark (or in a black box) for 72 hours and the other in the sunlight.

* Take one leaf from each of the plants.

* Put few drops of iodine solution on each of the leaves.

* The leaf kept in the sunlight will turn blue-black due to presence of starch.

* The leaf kept in the dark will not turn blue-black because of absence of starch.

In conclusion, the iodine is used to test for starch.

Select all of the following statements that represent examples of predation. Check All That Apply Deer eat the leaves of a tree.
Fantom [35]

Answer:

A snail eats a clam.

Explanation:

Interactions always occur between organisms in an ecosystem. An interaction between two organisms is called SYMBIOSIS. Symbiosis consists other types which includes PREDATION. Predation is a kind of symbiotic relationship between two organisms in which one kills and feeds on the other in order to obtain energy. The organism that kills is called the PREDATOR while the organism that is killed is called PREY.

In this example, a snail feeding on a clam best represents the example because the snail (PREDATOR) is obtaining energy by killing the clam (PREY). In other options, no organism is killed.

What happens when a hypothesis is not supported
Temka [501]
<span> For a start, when you have a question that needs answering in science, you formulate a null hypothesis. That is a negative statement which you then set out to prove or disprove. This is just a convention. So if your initial question is for example, "Does sugar dissolve in water?"

Your null hypothesis will be "Sugar does not dissolve in water."
You then set up your experiment and get some data.

Now if your data doesn't support your null hypothesis then you reject it and make the statement ,"Sugar does dissolve in water." As you can see from this simple example, a non-result is still a result so the idea of formulating new tests as mentioned by another answerer isn't necessary and in some ways is the incorrect thing to do. In science, hypotheses are often not supported by data and i would argue that this is the case a lot of the time. A non-result is still a result and you will have plenty to write about whichever way it goes. </span>
