Study Questions: Chapter 28 1.) Archaea and Bacteria are the oldest‚ structurally simplest and most abundant forms of life. 2.) Name and describe seven ways in which prokaryotes differ substantially from eukaryotes? Unicellularity- fundamentally single-celled Cell Size- can vary (large range changes with species) Nucleoid- lack a membrane-bound nucleus but rather a nucleoid region Cell Division/Genetic Recombination- binary fission (does not use spindle) and do not have a sexual cycle Internal

Bio 101- Introduction to Biological Sciences I. Brief History of Biology. List down the contribution(s) of the following philisophers/scientists to the science of Biology Pre-historic people: The earliest humans must have had and passed on knowledge about plants and animals to increase their chances of survival. This may have included knowledge of human and animal anatomy and aspects of animal behavior (such as migration patterns). However‚ the first major turning point in biological knowledge

germinating seeds and mealworms Bio Experiment : Comparing Rate of respiration in mealworms at different temperatures? Mealworms are cold-blooded animals and are unable to maintain a constant core temperature‚ hence respiration would therefore change with temperature. As glucose is oxidised‚ oxygen is used up and carbon dioxide and heat energy is produced. Increment in temperature / production of CO2 or O2 consumption would hence be good indicators for the experiment. 1) Hypothesis [What other

[pic] The Green Revolution The world’s worst recorded food disaster occurred in 1943 in British-ruled India. Known as the Bengal Famine‚ an estimated 4 million people died of hunger that year in eastern India (which included today’s Bangladesh). Initially‚ this catastrophe was attributed to an acute shortfall in food production in the area. However‚ Indian economist Amartya Sen (recipient of the Nobel Prize for Economics‚ 1998) has established that while food shortage was a contributor to the
