Explanation:
The first diagram represents the electron configuration of a carbon dioxide molecule.
Carbon dioxide as gaseous covalent molecule made up of two oxygen atoms and one central carbon atom:
CO₂
Carbon dioxide has linear structure with a bond angle of 180°.
In carbon dioxide, the atoms are covalent bonded.
The central atom is carbon and it joins up with two oxygen atoms.
The carbon has 4 valence electrons that goes into bonding in pairs. The oxygen atom has 6 valence electrons.
In order to complete their octet, they share their outermost electrons in the manner shown in the first diagram.

The two types are, aerobic where the final electron acceptor of the Electron Transport Chain is oxygen, and anaerobic, where the final electron acceptor of the Electron Transport Chain is a molecule aside from oxygen.
Answer:
we can determine the velocity of a wave when given the frequency along with the wavelength.
Explanation:
velocity = frequency × its wavelength
<span>Vitamin B6 will be administered to prevent inh associated peripheral neuropathy. Vitamin B6 can help with peripheral nueropathy, since it can relieve the pain from nerve damage, but the nurse must be careful. Too much vitamin B6 can have the opposite effect and cause nerve damage or numbness.</span>

Explanation:
Like carbon, nitrogen has its own biogeochemical cycle, circulating through the atmosphere, lithosphere, and hydrosphere (Figure 5). ... In this symbiotic association, the bacteria become encased in nodules that grow on the roots of plants, through which nitrogen that has been fixed by the resident bacteria is obtained.
