1. Sugar beets plants start from tiny seeds and grow to be large plants. Where does the bulk of their mass come from? A. nutrien
natka813 [3]

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.

Part A - The role of O2 in electron transport In mitochondrial electron transport, what is the direct role of O2?
Licemer1 [7]

Answer: (B) to function as the final electron acceptor in the electron transport chain.

Explanation:

Oxidative phosphorylation is a process that takes place in cellular respiration. It consists of two component pathways which includes the electron transport chain (etc) and chemiosmosis.

In etc the electrons are passed from one to another molecule, the energy is released by the electrochemical gradient.  

In chemiosmosis, the energy stored in the electrochemical gradient is used to produce energy molecules in the form of ATP (Adenosine triphosphate).  

The oxygen is present at the end of the etc. It's function is to accept the electrons also picks up the protons to form water. If oxygen is absent then no molecule will accept the electrons, the electron transport chain will stop. There will be no chemiosmosis as the ATP will not be produced in the absence of formation of a electron gradient.
