Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Answer:
Active transport of calcium into the sarcoplasmic reticulum.
Explanation:
- The sarcoplasmic reticulum (SR) is a membrane-bound structure found within muscle cells that is similar to the endoplasmic reticulum in other cells. The main function of the SR is to store calcium ions (Ca2+)
- In response to an action potential traveling along the t tubule, voltage-sensitive proteins change shape, opening calcium channels in the adjacent terminal cisterns of the sarcoplasmic reticulum.
Answer:
1. Opposable thumbs are one of the characteristics of the primates that enhances their fitness. The thickest digit found in the hand is the thumbs that possess the tendency to rotate and move in distinct orientations in comparison to other digits. This makes the primates possess the tendency to hold the objects with the help of their hands in comparison to other animals that can only hold objects like food with the help of their mouth.
2. In case, if a primate infant fails to possess opposable thumbs, then it would become much tougher for him or her to pick the objects. With practice and time, the individuals would develop the habit of holding things with the help of other digits of the hand, however, the grasping power will not be that much or it can be said that such individuals would fail to exhibit strong grasping power.
