Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus.
A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.
This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.
Hope this helps!
She picks up protein powder so she can make a protein shake-This represents ribosome, organelle specified for the biological protein synthesis (translation). In this case protein powder represents amino acids, structural units for the protein synthesis.
She eats part of it, and then stores the rest of it in a paper bag so she can eat it later. Paper bag in this case represents vacuole, organelle that contains molecules that have been engulfed.
Later in the day, she puts together several small packages of candies as gifts for her nieces and nephews. She labels each package and sends it through the mail
. This represents the function of the Golgi apparatus, the eukaryotic organelle that packages proteins into vesicles inside the cell before the vesicles are sent to their destination via certain patway.
When icebergs melt into the ocean it could be many variables, including warmer ocean temperatures, and warmer air temperatures. For icebergs to melt then the temperatures are getting warmer, thus concluding that the ocean water is getting warmer melting the iceberg. think of a glass of cold water with ice in it, over long periods of time the atmosphere temperature warms the water then slowly melting the ice in the glass. this is what's happening to icebergs in the ocean.
Answer:
Biotechnology is used to modify organisms, genetically, the effect of which is still not known. These genetically modified organisms, including bacteria, can escape in the wild and may disturb the balance of the ecosystem. This, as a result, may hurt biodiversity
