Answer:
A
Explanation:
water molecules are combined to make food
Answer:
hydroelectric , hydrogen fuel cells , solar power , geothermal , wind power
Explanation:
all of these has little to no waste being produced and have little to no impact on the environment .
Answer:Non-covalent bonds
Explanation:
The Non-covalent bonds are bonds such as van der Waals forces of attraction, the Hydrogen bonds, hydrophobic bonds and so on. The Non-covalent bonds are very important types of bonding in large biological molecules.
Just like the question says, the Non-covalent bonds, ''makes it possible for a macromolecule to interact with great specificity with just one out of the many thousands of different molecules present inside a cell".
Ionic bonding is also a Non-covalent bonding. They(Non-covalent bonds) helps in the stability of large macromolecules.

1. The answer is option E, that is None of the above is correct.
As a polymer becomes more crystalline,
its melting point doesn't decreases, its density doesn't decreases, its stiffness doesn't decreases and its yield stress doesn't decreases.
2. The answer is option B, that is the molecules are arranged in sheets, with their long axes parallel and their ends aligned as well.
In the smectic A liquid-crystalline phase, molecules are arranged in sheets, with their long axes parallel and their ends aligned as well.
3. For a substitutional alloy to form, the two metals combined must have similar atomic radii and chemical bonding properties.
