As global temperatures increase, certain organisms will br more affected than others. the changes associated with global warming may result in an increase in sea level. which organisms will be affected most as a result of the change in sea level

1) How is DNA compacted to form a chromosome?

2) How do cells undergo differentiation to form the numerous types of cells in the body?

3) What are some functions for non-coding DNA [e.g. Centromere, telomere, promoter, terminator, silencer, enhancer, introns (alternative splicing)]

Explanation:

1) Involves packing of DNA that involves DNA associating with H1, H2a, H2b, H3, H4 histone, scaffolding proteins, and link genes)

2) Since all somatic cells are genetically identical, differentiation involves silencing certain genes through different chemical signals that the stem cell's environment is in, resulting in certain genes related to its function being expressed while other genes are silenced.

3) Non-coding sequences although the bulk of DNA has numerous important roles. ( Centromere allow for association of kinetochore proteins to form kinetochore that acts as a site of attachment for microfibrils during mitosis or meiosis) (telomere acts as sacrificial DNA that prevents erosion of Coding DNA during every round of semi-conservative DNA replication)...
