Answer:
The relationship between environment, variation and selection lay the foundation for natural selection and evolution.
Genetic variations are present among species due to number of reasons like recombination or crossing over during meiosis, mutations, random fertilization etc. These factors bring changes among the members of a species. Some of the species become better adapted to survive in a particular environment whereas some are not better adapted and become extinct over a period of time. The environment selects the organisms that are best adapted to survive and hence lead to variations.

Chromosomes are parts of a cell that carries genetic information inform of genes, they contain DNA molecules packaged around histone proteins. Diploid number of chromosomes means that a cell has both sets of homologous chromosomes while haploid is used to refer to a cell that has one set of chromosomes and therefore a single set of genes.Mitosis is a type of cell division that takes place in the somatic cells (body cells) resulting to two daughter cells with the same number of chromosomes as the parent cell (diploid). Therefore, in this case a somatic cell will have 48 chromosomes (diploid number 2n).
