An image is formed due to reflection of light by a plane mirror. In a completely dark room there is no light so no image will be formed by the mirror placed in the room. Hence we will not be able to see our image in a mirror placed in a completely dark room.
Answer: Operant Conditioning
Some bears must have had undergone operant conditioning that is why they open their mouths for teeth cleaning and present their paws for nail clipping.
Operant conditioning is a form of learning in which a reward or punishment is given for some voluntary behavior.
Bears that have undergone operant conditioning are called food-conditioned bears. They are dangerous but learned to approach humans, or frequent human-occupied sites, in search of food (reward).
Biological classification is the process by which scientists group living organisms. Organisms are classified based on how similar they are. Historically, similarity was determined by examining the physical characteristics of an organism but modern classification uses a variety of techniques including genetic analysis.
Organisms are classified according to a system of seven ranks:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species
For example, the honey bee (Apis mellifera) would be classified in the following way:
1. Kingdom = Animalia
2. Phylum = Arthropoda
3. Class = Insecta
4. Order = Hymenoptera
5. Family = Apidae
6. Genus = Apis
7. Species = Apis mellifera
Species names are always written including the Genus in either full or abbreviated, for example, Apis mellifera or A. mellifera respectively.
