Answer:
As the gas spins faster, it heats up and becomes as a protostar. Eventually the temperature reaches 15,000,000 degrees and nuclear fusion occurs in the cloud's core. The cloud begins to glow brightly, contracts a little, and becomes stable.
Explanation:
please give me a heart
I'm pretty sure the answer is nonliving.
The energy from the sun is the most responsible for the water cycles. Think about it: Without the energy from the sun, water would not be able to evaporate (which is the first process in the water cycle), so it wouldn't be able to transition to the next process.
Operons are gene regulatory mechanisms that involve promoting and repressing genes that are involved in the metabolism of organic substances (i.e. sugars). Living organisms have the innate ability to metabolize glucose as the main source of energy. Although, in the absence of glucose, the organism must "learn" to use sugars other than glucose (such as lactose) in order to survive.
For instance, in the <em>lac </em>operon:
In the absence of glucose, various regulatory proteins promote the transcription of the gene related to the metabolism of lactose. This will ultimately lead to the production of the enzyme beta lactosidase which will enable the organism to use lactose as energy in the absence of glucose. This will therefore increase the chances of the organism for survival and will be naturally selected for evolution.
Answer:
A solution at pH 6 contains<u><em> 100 times more H+</em></u> than the same amount of solution at pH 8.
Explanation:
pH of a substance determines the hydrogen ion concentration of a solution. Acidic solution tend to have a higher concentration of H+ ions as compared to that of water. They have a concentration greater than 1 × 10^{-7} M. Basic solutions have lesser concentration of H+ ions as compared to that of water. They have a concentration lesser than 1 × 10^{-7} M. A solution from pH range 1 to 6 will be acidic. A solution from pH rage 8-10 will be basic.
