The risk of schizophrenia among biological relatives is greatest for identical twins. This is a true statement.
<h3>What is schizophrenia?</h3>
Schizophrenia is a neurological disorder that causes an affected individual to lose touch of reality.
Schizophrenia can be caused by the following:
- Genetics: Gene defects caused by mutation such as deletions or duplications of genetic material increases risk of schizophrenia.
- Environment: Urbanicity, migration, cannabis, childhood traumas, infectious agents, obstetrical complications and psychosocial factors
- Brain chemistry and circuit
- Brain abnormalities: Impaired communication between brain regions leads to the associated symptoms and cognitive changes.
According to research, the risk of schizophrenia among biological relatives is greatest for identical twins because they are genetically identical.

An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
