Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.

<h3><u>Answer;</u></h3>
<em>ATP and NADPH</em>
<h3><u>Explanation;</u></h3>
Three-carbon molecules of PGA are converted to G3P small sugar molecules by <em><u>ATP and NADPH</u></em>, which come from the light reaction.
- <em><u>Photosynthesis</u></em>, a process in which green plants use energy from the sun to make their own food, involves two types of reactions, light reactions in light stage and light independent reactions in dark stage.
- During <em><u>the light reactions ATP and NADH are generated from the electron transport chains</u></em>, which are then taken to the second stage (light independent stage) of photosynthesis. During the Light independent stage the energy stored in ATP and NADH is <em><u>used to convert 3-carbon PGA to G3P</u></em>.
Answer:
3 characteristic
Explanation:
1- it contains sulfur when bacteria found sulfur in the media then it produces H2S (hydrogen sulfate). It causes the blackening of the media which acts as an indicator that bacteria can produce H2S.
2- Indol is the second characteristic. If bacteria is indol positive than it changes color from yellow to pink when the reagent is added.
3- Motility: if bacteria are motile than it's motility is easily visible in the media.
