Question

• Long molecules of DNA can fit into the tiny nucleus because within each chromosome the DNA is packed into an elaborate, multilevel system of coiling and folding.
• Sexual reproduction may enhance fitness by producing offspring of varied genetic makeup, speeding adaptation to a changing environment.  
• Cancer cells do not respond normally to the specialized proteins that control the cell cycle; they divide excessively and may invade other tissues of the body.  
• During cell division, each daughter cell receives one identical set of chromosomes from the original parent cell.  

match the theme to each example

- information flow

- relationship of structure to function

- pathways that transform energy and matter

- interactions within biological system

- evolution

Answer 1

Long molecules of DNA can fit into the tiny nucleus because within each chromosome the DNA is packed into an elaborate, multilevel system of coiling and folding- relationship of strucutre to function

This is because due to the strucutre of Dna and how it is transformed from such a great length into minute comolex strucutre inside the nucleus also reflects how it performs all the function at the sub cellular level

Sexual reproduction may enhance fitness by producing offspring of varied genetic makeup, speeding adaptation to a changing environment.- Evolution

Any change or difference in the genetic makeup of body in time span of many years and adaptation for many environmental changes can be seen as evolution.

Cancer cells do not respond normally to the specialized proteins that control the cell cycle; they divide excessively and may invade other tissues of the body. - interactions within biological system.

Different cells reacting with each other and somehow changing the set pattern of behavior of cells.

During cell division, each daughter cell receives one identical set of chromosomes from the original parent cell. - information flow and pathways that transform energy and matter.

Cell division requires energy so it is process in which energy is being transformed and as the chromosomes are passed from one cell to another, information also flows between parent cells and offsprings
