Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [32] It is a sub-discipline of both biology and chemistry, and from a reductionist point of view it is fundamental in biology. Biochemistry is closely related to molecular biology, cell biology, genetics, and physiology.
Human biology is an interdisciplinary area of academic study that examines humans through the influences and interplay of many diverse fields such as genetics, evolution, physiology, anatomy, epidemiology, anthropology, ecology, nutrition, population genetics, and sociocultural influences.
Vaginal intercourse between private individuals is part of their private sphere. Sexual intercourse between an adult and a young person is generally only permitted after the age of consent in the respective country has been reached, though some countries/jurisdictions have special exceptions to this rule. These exceptions may include when the ...
[2] The development of sexual differences begins with the XY sex-determination system that is present in humans, and complex mechanisms are responsible for the development of the phenotypic differences between male and female humans from an undifferentiated zygote . [ 3 ]
The human brain. Differences in male and female brain size are relative to body size. [83] Early research into the differences between male and female brains showed that male brains are, on average, larger than female brains. This research was frequently cited to support the assertion that women are less intelligent than men.
Biologists classify humans, along with only a few other species, as great apes (species in the family Hominidae).The living Hominidae include two distinct species of chimpanzee (the bonobo, Pan paniscus, and the chimpanzee, Pan troglodytes), two species of gorilla (the western gorilla, Gorilla gorilla, and the eastern gorilla, Gorilla graueri), and two species of orangutan (the Bornean ...
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
The equation transforms the proportion of nucleotide differences between taxa 1 and 2 (p 12 = 4/18; the four site patterns that differ between taxa 1 and 2 are indicated with asterisks) into an evolutionary distance (in this case d 12 =0.2635 substitutions per site).
