<span>The person who has a small intestine that has fewer villi than normal would most likely be u</span>nderweight. The villi of the small intestines are the small structures that do the absorbing of the nutrients. Having less of these structures, less nutrients are absorbed and the person is more likely to be malnourished.
The correct answer is proteins.
Proteins have four structures; (1) primary, (2) secondary, (3) tertiary, and (4) quaternary. Primary structures of proteins are formation of peptides and the peptide bonds between amino acids. Secondary structures of proteins involves the amino acid composition leading to hydrophobic interactions forming either alpha helices or beta sheets. Interactions between secondary structures of proteins will make the tertiary structure which is either soluble (globular) or insoluble (fibrous) proteins. Quaternary structures are the combination of two or more tertiary structures and these are called subunits.
The ant and aphids have mutualism type of relationship because they both profit from one another. The aphids are protected while the ant is fed.
<h3>What is Mutualism?</h3>
- Mutualism is a partnership in which both species participate and gain from it.
- In this instance, ants profit because they eat the waste products left behind by aphids, while aphids profit because ants guard them.
- An illustration of a mutualistic relationship is the one between an animal called an oxpecker and a rhinoceros or zebra.
- The spider crab continues to be hidden from predators.
- Bees with flowers - Another mutualistic link exists between bees and flowers.
- Bees move between flowers to collect the nectar they require to produce honey.
- Pollination occurs when the bee transfers pollen from one plant to another.
