Answer:
The economic principle that helps ensure that scarce resources are allocated efficiently is "the profit motive."
Explanation:
In economics, the profit motive is the inspiration of organizations that function so as to exploit their profits. Conventional micro-economic concept suggests that the eventual goal of a commercial is to make money. Specified differently, the aim for a business's presence is to chance a profit. The profit motive is the craving to make money. In a free market (where people willingly swap money, goods and services, the profit motive agrees who grows what. In theory, the profit motive dispenses resources efficiently, but in practice there are some problems.
Answer:
The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.
Explanation:
Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.
The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.
The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.
The other options are not correct, because
- <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
- <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
- <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>
Answer: A!
Explanation: All biological organisms play a part in the earth's ecosystem, but consumers get energy from eating other organisms and producers make energy on their own. Grass is a producer, a self-sustaining organism that obtains its energy from the sun. In the process, it introduces new organic substances into the food chain and plays a key role for consumers. Grass forms the basis of the food chain because of this ability.
