Answer:

1.  B. carbon dioxide taken in from the surrounding air

2. A. Root

Explanation:

Sugar beet plant carries out photosynthesis and stores the excess of the sucrose in its taproots. During the process of photosynthesis, the plant absorbs CO2 from the air, water from the soil and synthesizes organic sugars in the presence of sunlight.

Atmospheric CO2 contributes carbon and oxygen atoms to the formed sugars which in turn are stored in plant parts. Therefore, atmospheric CO2 makes most of the mass of the photosynthesizing plants such as sugar beets. The taproots of beet plants are modified into storage roots to store the excess of the organic sugars.

Write about how the group of rock layers in record a forme include tilting erosion and folding
neonofarm [45]

Answer:

Most sedimentary rocks are formed in level layers. Therefore, the occurrence of tilted rock layers is evidence of mountain building. ... Tilting can also result when rocks are pushed upward, or uplifted. In some areas of the world, rock layers are so severely tilted that they may be bottom side up. Layered rocks form when particles settle from water or air. Steno's Law of Original Horizontality states that most sediments, when originally formed, were laid down horizontally. ... Rock layers are also called strata (the plural form of the Latin word stratum), and stratigraphy is the science of strata.
