Which of the following statements best describes the structure and function of a carbohydrate?

a. carbohydrates are made up of starchy monomers and are used for structure, protection, and reproduction.
b. carbohydrates are made up of sucrose molecules that are important for transportation and protein synthesis.
c. carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.
d. carbohydrates are long, winding molecules made up of amino acids and are important in the synthesis of fats and hormones.

The correct answer is C. Carbohydrates are large molecules made up of monosaccharides and are used by organisms for energy storage.

Carbohydrates are the large group of organic compounds, which are comprised of Carbon, hydrogen, and Oxygen. They mainly include simple sugar (like glucose, fructose) and starch ( present in food like potato, grains).

They are the most essential and readily available source of energy for all life forms.

Complex carbohydrates ( polysaccharides) like starch are made up of simple sugar called monosaccharide ( like glucose).

Thus, option C) is the right answer.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
