Answer:
The correct answer will be- the color change will be observed and the solution will turn purplish-black.
Explanation:
Iodine test is performed to test the presence of the carbohydrates mainly starch.
The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.
In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.
Is this like on a test or like homeowork?
Answer:
<u>C</u>
Explanation:
The reason why there are more hares than foxes in the ecosystem is because if only 10% of the energy gets passed on to the next trophic level, then you need to have more lower level animals available to supports the animals higher up the food chain. The fox must eat several hares to gain enough energy for growth and development.
Answer:
Swim bladder
Explanation:
Swim bladder is an organ in bony fishes such as catfish that controls their buoyancy. It is also known as air bladder. The swim bladder contains gas, mainly oxygen and functions as a hydrostatic organ.
As the fish moves in deeper water, the gas in the swim bladder is contracted which decreases the volume of swim bladder.
The answer is <span>Gap Junction
Gap junction is a small gap between the cells that used to transmit signall to the cells. This gap will allow the heart muscle to be activated in unison. Coordinated contractions are important for heart muscle because it creates the force that needed to pump the blood.</span>
