The article “Biology is Beauty” by Geoffrey Cowley touches on the aspects behind beauty. The article states that everyone shares a sense of what is attractive. Basically‚ Cowley is stating that people are attracted to what is on the outside‚ even if we do not know it. Even though points of attraction can vary over societies‚ beauty is an innate quality we all think of. The article touches on a few examples that the author feels explains. First‚ Cowley says that humans love symmetry; people prefer

The function of a capsid‚ in virus biology‚ is to serve as a protective outer layer that protects the genetic material of the virus from the host’s defensive cells. The capsid is made up of proteins. The nucleic acid is what is contained within the capsid‚ which is a group of long‚ linear macromolecules‚ consisting of either DNA or RNA. There are two different cycles in which the virus uses a host cell to replicate and reproduce itself. These two cycles are known as the lytic cycle‚ and the lysogenic

Before watching the film I did not think biology had anything to do with racism. I believe scientist tried to prove that race was biological in order to justify the actions against the non-white race. I had never really thought about where race had come from but was surprised‚ but not hard to believe‚ to hear in the film that race was created by humans to describe social and cultural differences. Knowing that race is not biological will not eliminate racisms today. Those that are racist today

In biology and ecology‚ extinction is the end of an organism or of a group of organisms (taxon)‚ normally a species. The moment of extinction is generally considered to be the death of the last individual of the species‚ although the capacity to breed and recover may have been lost before this point. Because a species’ potential range may be very large‚ determining this moment is difficult‚ and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa‚ where a species
