The correct answer is "catalase in human tissues neutralizes it".
Hydrogen peroxide works to kill bacteria by forming free radicals which exerts oxidative stress in the bacterial cell leading mostly to cell membrane damage and lysis of the bacterial cells. In the environment of human tissues wherein there is catalase, hydrogen peroxide is converted to water and oxygen which has no antiseptic effect.
TTTT is the correct answer
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
Answer: A) C)
Explanation:
Sedimentary rocks are formed and made in one situation when sediment is deposited out of ice, wind, gravity, air, and water.
That sediment is formed when it comes to erosion and weathering. It is happening with breakdown of rock into some loose material and that is why correct answers are erosion and weathering.
Answer: A
Why? It doesn’t kill all living animals(might kill some). No acid rain, and may cause extinction of plants but not most plants. So it has to be A
