TiliK225 [7]

Answer:

Scientists learn how climatic changes during the ice age affected life in this region by analyzing specimens found in these tar pits  

Explanation:

La Brea Tar Pits are a group of tar pits in Los Angeles. Many preserved remains of ancient organisms (i.e., fossils) were extracted from the tar, including, among others, Western horses, prehistoric camels, three-toed tapirs, rodent bones, insects, mollusks, wood, plants, etc. The oldest fossils have been dated to be approximately 38,000 years ago by radiometric techniques. Moreover, the Last Glacial Period was the most recent glacial period within the Quaternary glaciation, which encompassed the period between 115,000 to 10,000 years ago. This period (LGP) encompassed the Last Glacial Maximum (LGM), which occurred about 20,000 years ago. In consequence, many of the fossils found in La Brea Tar Pits evidence how the ice age affected life in this region. Moreover, many of the fossil species extracted from the tar are still present today, thereby indicating how these species adapted to fluctuating climatic conditions, whereas certain species couldn't adapt fast enough as the environment changed and therefore they went extinct.

If a plant were to absorb a substance that readily reacts with carbon dioxide in the stroma, the dark reactions would be most li
Assoli18 [71]
The right answer is the dark reaction would stop happening.
The Calvin cycle (or dark reactions, independent of the sunlight) makes it possible to manufacture glucose, an energy molecule, from carbon dioxide. This is called carbon fixation.There are three reactions of this cycle take place in the stroma of chloroplasts: the first of which is the fixation of carbon dioxide. which is a limiting step in this cycle.If a substance other than the components of the dark reactions absorbs and uses carbon dioxide, the carbon cycle will not be able to occur for lack of one of these ingredients which is the CO2.
