The next concept—scale, proportion, and quantity—concerns the sizes of things and the mathematical relationships among disparate elements. The next four concepts—systems and system models, energy and matter flows, structure and function, and stability and change—are interrelated in that the first is illuminated by the other three. Each concept also stands alone as one that occurs in virtually all areas of science and is an important consideration for engineered systems as well.
During this discussion students are introduced to: The following DNA worksheets are included with this video: Our Meiosis DVD begins by comparing asexual and sexual reproduction and describing chromosomes and homologous pairs. The difference between haploid and diploid cells and the three major eukaryotic life cycles are then described.
In the process students are introduced to phenomena such as crossing over and provided an explanation of how meiosis creates genetic variability in a species. The following meiosis worksheets are included with this video: Our Mitosis Video starts by introducing the cell cycle and briefly describing the process of binary fusion in prokaryotic cells before going on to a detailed look at the eukaryotic cell cycle from the G1, S and G2 phases of interphase through the prophase, metaphase, anaphase and telophase phases of mitosis.
The difference between cytokinesis in animal and plant cells is then illustrated.
The program concludes by explaining why an understanding of cellular division is critical to: The following mitosis worksheets are included with this video: Our Mendel DVD delves into the fundamental aspects of genetic inheritance and how Mendel discovered the principles that form the foundation of modern genetics.
The program first goes to Mendel's pea garden to investigate how Mendel came to propose the Laws of Dominance, Independent Assortment and Segregation and how those laws have been modified as a result of work done by those that followed Mendel. The program later explores sex-linked traits, the use of Punnet squares, incomplete dominance, codominance, and polygenic inheritance.
The following Mendel worksheets are included with this video: Our Human Genome DVD begins by looking at single gene genetic disorders including recessive disorders such as Tay-Sachs and sickle-cell anemia, dominant disorders such as Huntington's disease, and sex-linked disorders such as hemophilia and color blindness.
The program then looks at polygenic inheritance and environmental influences on the expression of genes. Chromosomal inheritance of disorders such as Down syndrome are then explored before looking at the ethical issues involved in genetic testing and the hope promised by the Human Genome Project.
The following human genome worksheets are included with this video: Our Biotechnology DVD first looks at major research areas in biotechnology such as the Human Genome Project and the various forms of recombinant DNA technology that produce transgenic plants and animals.
The program then goes on to look at the tools used by biotechnologists such as restriction enzymes, plasmids, vector and vector less insertion of genes into genomes, and the production of genes via polymerase chain reactions.
The program then concludes by looking at the future of biotechnology and some of the environmental, economic, and ethical issues raised by biotech.

Innovators of Shelterwrap Polystyrene Fanfold Insulation Underlayment. Whether you need some basic foam cutting of sheets and blocks or you need some more complex computer aided parts fabricated, Shelter Enterprises does it best.
The unit cell is defined as the smallest repeating unit having the full symmetry of the crystal structure. The geometry of the unit cell is defined as a parallelepiped, providing six lattice parameters taken as the lengths of the cell edges (a, b, c) and the angles between them (α.
Aquaporins are "the plumbing system for cells". Water moves through cells in an organized way, most rapidly in tissues that have aquaporin water channels. For many years, scientists assumed that water leaked through the cell membrane, and some water does.
