It's no coincidence that our bodies feel a little creakier as we age. The trillions of cells that make up our skeleton age too, and some change in ways that weaken the very structure of our bones.

To extend and apply their improved models challenge learners to create a totally new model to illustrate and communicate the dynamic nature and function of the cell as illustrated in the narrative.

The cell nucleus is the site of many important biological functions of the eukaryotic cell. These processes include transcription, replication, splicing and ribosome biogenesis.

Cell: Structure and Functions The cell is the structural and functional unit of living organisms. It was discovered by Robert Hooke in 1665. Cell in Latin means “little room”.

Includes laboratory. A study of the dynamic aspects of the structure, function and regulation of eukaryotic cells. The molecular nature of the gene and gene expression are examined. The intercellular ...

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025 ...

Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans. Their defining feature is the presence of membrane-bound organelles, ...

Within multicellular organisms, tissues are organized communities of cells that work together to carry out a specific function. The exact role of a tissue in an organism depends on what types of ...

Yale researchers and their colleagues in Hungary have discovered that cells in the hypothalamus — an area of the brain that controls functions like hunger and body temperature — play a major role in ...
