Answer: The environment.
Explanation: The environment consists of both the factors like biotic and abiotic factors. The interaction between these factors defines an environment.
The abiotic factors found in the environment consists of the soil, mountain, water, clouds and other non living parts. The biotic factors of the environment consists of the plants and animals.
Environment consists of both biotic and abiotic factors.
b. glycerol is made of fatty acids.
proteins are made of amino acids.
nucleotides are made of nucleic acids.
The correct statement about macromolecules is 'Proteins are made of amino acids'. It should be noted that in other options, the statements have a part reversed and therefore they are incorrect.
The correct statement about macromolecules is 'Proteins are made of amino acids'. Macromolecules are large, complex molecules that have a high molecular weight. They are mostly built from single subunits, or building blocks, called monomers. In this context, amino acids are the monomers that make up proteins which are a type of macromolecule.
To provide some clarity on the incorrect options: `Simple sugars are not made of polysaccharides` but the other way around. Polysaccharides are complex carbohydrates that are made up of simple sugar monomers. Similarly, `glycerol is not made of fatty acids`, rather, it combines with fatty acids to form lipids. Lastly, `nucleotides are not made of nucleic acids`, but nucleic acids are made of nucleotides. So, it's important to understand the relationships between these biochemistry terms to correctly understand the nature of macromolecules.

The design attribute of water that allows for many unusual life-supporting properties is its unique structure and properties, such as high specific heat capacity, the ability to form hydrogen bonds and high heat of vaporization.
One key property is water's high specific heat capacity, which means it can absorb and release large amounts of heat without much change in temperature. This property helps regulate temperature in living organisms and prevents drastic temperature fluctuations.
Another important property is water's ability to form hydrogen bonds. These bonds give water its cohesion and surface tension, allowing water to stick to itself and other substances. This property is essential for the transport of nutrients and waste in biological systems, as well as the movement of water in plants through capillary action.
Additionally, water's high heat of vaporization enables efficient cooling through evaporation. This cooling mechanism is crucial for maintaining body temperature in animals and preventing overheating.
