slavikrds [6]

Answer:

social facilitation

Explanation:

The concept of social facilitation was first proposed by Norman Triplett. After observing a cycling event, in which he noticed that cyclist performed better when they have others around competing with them, rather than cycling alone just against time. This led him to duct an experiment where he gave some children strings to wound fishing reel. He observed that, children wound the fishing reel faster in the presence of other children performing similar task, when compared to when perform such task alone.

This concept discovered by Norman Triplett, best illustrates the concept of social facilitation, which posits that, individuals tend to perform better in the mere presence of others or when they perform a task with others, than when performing the task alone.

The targets for anti-fungal drugs are much more limited than antibiotics or anti-viral medications. Why?
Minchanka [31]

Answer:The reason for this is because fungi and their host are eukaryotic and in treatment of fungal infections drug used can also affect their host.

Explanation:

Antifungal drugs are drugs used in the treatment of fungal infections and so are antibiotics and antiviral drugs used to treat bacterial infections and viral infections respectively.

Fungi and their host are both eukaryotic and this make them closely related. They attack by colonizing and destroying the tissues of the animal host. When treating infections caused by fungi, the compounds used to kill fungi also harm the animal host because of the eukaryotic property they both possessed, this therefore set limitations to antifungal drugs. Unlike fungi, bacteria attack prokaryotic cell and also bacterial infections are systematic not superficial or topical like fungal infections.
