Answer:

H2 is Molecular hydrogen. It is a molecule of hydrogen that consists of two hydrogen atoms bonded together by one single bond (also known as a sigma bond). A subscript also denotes how many of a particular atom is in a molecule, thus H2 has two hydrogens. 2H, on the other hand, denotes two moles of elemental hydrogen.

The first one in the box is agree are disagree then tell me why you agree or disagree
Dimas [21]

Answer:

his study aimed to evaluate the possibility of cotton waste enrichment with glycine betaine (GB) for production of two strains (P9, P10) of king oyster (Pleurotus eryngii). Cotton waste was used as (100%) control (T0 = cotton waste) and augmented with various combinations of GB, (T1 = 2 mmol L−1, T2 = 4 mmol L−1, T3 = 6 mmol L−1, T4 = 8 mmol L−1 and T5 = 10 mmol L−1). The response of king oyster to GB was evaluated by earliness, yield, biological efficiency (BE), minerals (nitrogen, phosphorus, potassium, zinc (Zn), copper (Cu), magnesium (Mg), manganese (Mn), iron (Fe), sodium (Na), calcium (Ca)), total sugars, total soluble solids, reducing sugars, non‐reducing sugars, ascorbic acid, proximate (crude protein, carbohydrates, crude fibers, ash, fats) content of fruiting body and Fourier‐transform infrared (FTIR) spectroscopy analysis compared with the control substrate (cotton waste).

RESULTS

The earliness, yield, and BE were higher as compared to control substrate and increased with an augmentation in the concentration of GB within the cotton waste. Two strains showed (on dry weight basis) 33.9–54.9 mg g−1 nitrogen, 6.8–12.5 mg g−1 phosphorus, 16.9–25.1 mg g−1 potassium, 40.5–64.2 mg kg−1 Zn, 17.1–37.3 mg kg−1 Cu, 1174–1325 mg kg−1 Mg, 20.1–29.1 mg kg−1 Mn, 129–265 mg kg−1 Fe, 779–835 mg kg−1 Ca), 6.3%–11.3% total sugars, 7.3–14.9 °Brix total soluble solids, 2.1–7.3% reducing sugars, 10.4–18.1% crude protein, 3.6–4.4% crude fiber and 5.6–16.7 mg (100 g)‐1 on various concentration of GB enrich cotton waste. Cotton waste enriched with GB significantly affected nutritional profile of king oyster mushroom.

CONCLUSION

The results revealed that GB enriched cotton waste can be used as an innovative substrate to enhance the yield and quality of king oyster mushroom.

Read the following quote. What do you think it means? Do you agree or disagree with the speaker? We teach girls shame... We make
Westkost [7]

I think this quote is explaining how girls are taught from the beginning, shame. When girls turn into women, they believe they must be quiet, they must be happy, and they must be perfect. I disagree with this quote for this generation. I believe that we have broken through those previous barriers and are now teaching women strength, courageousness, and the power to be ourselves. I do agree with the line, "they grow up to be women who have turned pretense into an art form.". From my experience, I believe that women cannot have the same emotions as men, because it may come across different. A powerful woman is seen as snarky or rude, whereas a powerful man is admired.
