The carbon cycle is the biogeochemical cycle by which carbon is exchanged among five spheres of the Earth, carbon (C) sinks: the biosphere, pedosphere, lithosphere, hydrosphere, and atmosphere (These are not mutually exclusive, see Glossary).
The fact that the human brain is not completely developed at birth means that <u>environment</u> greatly influence(s) human brain development.
Human brain development is a complex procedure and unlike other organs, the human brain is not completely developed at the time of birth.
Apart from the development inside the mother, the environment also has a major influence on the development of the human brain.
This is the reason, the brain of each person is influenced by the exposure to the environment that he gets. The development of the cognitive brain is associated with various environmental aspects of society. Hence, not all of the brain of a person has been developed at the time of birth.

I believe the answer is -0.4
Answer:
chromosomes line up along the middle plate in double file
sister chromatids split
four haploid daughter cells are formed
Explanation:
Crossing over or recombination is the interchange of genetic material between non-sister chromatids. This process (crossing over) occurs during the prophase of meiosis I. Meiosis II is the second meiotic division that involves the separation of sister chromatids. In metaphase II, the centromeres of paired chromatids align on the equatorial plate of each daughter cell to be subsequently separated in anaphase II. At the end of meiosis II, four daughter cells are formed (i.e., four gametes), each with the same haploid number of chromosomes.
