Cual es el enlace covalente de H2 SE​
Veronika [31]
Su enlace es covalente apolar.
Explicación:
Ambas moléculas se unen para formar un compuesto estable, y alcanzar el "octeto".
El selenio tiene 6 electrones de valencia, y le faltaría dos electrones, para tener los 8 electrones, y así, cumplir su octeto, y volverse estable.
Por el contrario, el hidrógeno, se va a parecer al elemento noble más estable, el Helio (He), por lo cual, puede compartir sus electrones con el Selenio, así el Hidrógeno tendría 2 electrones, volviéndose estable, y el Selenio 8.
Sabiendo lo anterior, podemos calcular si es covalente polar o apolar, con una tabla de electronegatividad, que puedes encontrar en internet.
Restas el valor del Selenio al Hidrógeno, y el resultado que te de, lo comparas son los valores de referencia existentes, quedando como:
Se(2.6)-H(2.2)= 0.4
Covalente apolar: 0-0.4
Covalente polar: 0.5-1.6

What’s the average water content of an animal or plant cell?
slega [8]

it becomes how much of the plant is composed of non-cellular material, like wood. Trees are usually between 60 and 80% water, bushier, less woody plants and water plants can be up to 95% water. Finally, as pointed out, humans are animals, so go with the animal stats for humans. 68% water about average.

Which of the following best describes the main purpose of the combined processes of glycolysis and cellular respiration?1 breaki
max2010maxim [7]

Answer:

4. transforming the energy in glucose and related molecules in a chemical form that cells can use for work

Explanation:

Glycolysis breaks down glucose into two molecules of pyruvate which is transformed into acetyl CoA to enter the Kreb's cycle. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy stored in the glucose molecule is released during glycolysis and Kreb's cycle. The released energy is stored in the form of NADH and FADH2 as well as in few molecules of ATP.

The NADH and FADH2 enter the final step of cellular respiration, the oxidative phosphorylation. Here, NADH and FADH2 are oxidized with the help of electron transport chain (ETC). During the transfer of electrons through ETC, the proton motive force is generated which then helps in ATP synthesis.

Hence, the three steps of cellular respiration (glycolysis + Kreb's cycle + oxidative phosphorylation) retrieve the energy from nutrients such as glucose and store it in the form of ATP. ATP is used by cells as an energy source for various other functions.
