Answer: Exhaled air containing Carbon dioxide bubbles react with water to form carbonic acid . The solution turn acidic and turn from green to yellow.
Explanation:
Exhaled carbondioxide bubbles reacts with water to form carbonic acid, the solution will turn acidic. Carbonic acid is a weak acid that decrease pH. An indicator of it shows that the solution turns from green to yellow.
Co2+ H2O= H2Co3.
The solution then dissociate to give H ion and hydrogen carbonates ion.
Answer:
7) a. Absorbed: black surfaces absorb light, like in a playground.
b. Transmitted: when light falls on transparent objects, it is transmitted, goes straight through the object, like the clear glass of a window
c. Reflected: when light falls on a smooth, shiny object, it bounces off in one particular direction, like looking at the smooth surface of a lake
Well, first off we would have more unlimited power supply and we would be able to get it easier because, the sun can produce harmful RB rays, all we would need to do is process it through a machine that can make it into a nuclear radiation rod that could be put into every electrical thing on this planet. We can also kill every one with the fire of a missile, and we could wipe the electrical currents of a nation out in one go.

D. Mitosis involves the splitting of a cell and its content. According to the State University of New York, mitosis has five phases: interphase, prophase, metaphase, anaphase and telophase. During interphase, the cell prepares for mitosis, and chromosomes are usually not visible. In prophase, the chromosomes start to coil, the nuclear membrane wanes and a spindle-like formation appears. In metaphase, the chromosomes align for replication. In anaphase, the chromatid separates, doubling the number of chromosomes to 92. In telophase, the chromosomes uncoil, the nuclear membrane reappears and the cell splits into two daughter cells, each having 46 chromosomes..
