1. The classification system developed by Linnaeus in the early 1700s divided living organisms into plant and animal kingdoms. Today‚ that has been expanded into five kingdoms. Which of the following inventions was most responsible for creating the need for the additional three kingdoms and why? (2 points) (0 pts) Fossil fuel-based transportation made it easier to explore and discover new species. (0 pts) Genetic engineering created new species which then needed new kingdoms. (2 pts) Microscopes

Learning about Cells. First thing I want to show you is two beautiful pictures of a Cell. Imagine all of this is in something so small we cannot see it with our naked eyes. About 10‚000 average-sized human cells can fit on the head of a pin. There are a few exceptions‚ but the average cell is very tiny. Here are a few beautiful examples of a cell structure to kind of give you an idea of its beauty‚ and how they fit together. Plasma Membrane (cell membrane) First we are going to learn about

time period of the cell cycle consists of the cell division stages. The other phases‚ known as G1‚ S and G2 take up the majority of the time. Cell division by mitosis is important during growth of eukaryotic organisms and is the way in which eukaryotes increase their cell numbers‚ either in a population of a single celled organism‚ such as Amoeba or yeast‚ or within the body of a multicellular organism. Growth may be allometric meaning that different parts of the organism grow at different

Themes in the Study of Life Campbell Biology 9th ed. Chapter 1 What is Biology? • Biology is the scientific study of life • Biologists ask questions such as – – – How do multicelled organisms develop? How does the human mind work? How do living things interact in communities? • Life defies a simple‚ one-sentence definition • Life is recognized by what living things do Some Properties of Life • Order • Evolutionary adaptation • Response to environment • Reproduction • Growth and development
