B is the answer. I repeat B is the answer.
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.
They all keep the plant alive and healthy! rawr XD
Hello! Allow me to help!
Your question: Can the atmosphere change in its composition?
My answer: Our atmosphere is made up of many different gases. The most common gases are nitrogen, oxygen and argon. But, the exact amount of each gas is always changing.
Why is my answer correct? Good question! Allow me to explain: Tropical deforestation not only has a large impact on the carbon cycle and climate, but also affects the chemistry of the atmosphere. Together with the carbon cycle and weather patterns land use can affect the concentrations of greenhouse gases like methane and ozone.
Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds. From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.
Changes in atmospheric composition and the rest of the climate system would include temperature, rainfall, and humidity, which would affect the economic importance, geographical distribution, and management of diseases effecting crop production.
Hope this helps! UwU
