Jim Sciba 8/31/16 Origins of Ancient Civilization Essay #1 In the last 10‚000 years‚ the origins of domestication and the rise of cities and states are the hallmark for human progress leading up to the modern world. Despite the ethnocentric biases that entails‚ the development of densely populated cities and states has created many disadvantages and in comparison to small‚ family-based‚ egalitarian societies‚ it is more satisfying than living in cities and states. The development of densely populated

The evolution of plants has resulted in increasing levels of complexity‚ from the earliest algal mats‚ through bryophytes‚ lycopods‚ ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive‚ especially in the environments in which they evolved‚ each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1‚200 million years ago. In the Ordovician period

deforestation keeps on happening? I strongly believe that we need to stop deforestation before it is too late‚ or else we‚ humans‚ will suffer a lot from it. It has been told that forests are our world lungs. As many of us have known‚ every green plant can do photosynthesis‚ a process of producing oxygen from carbon dioxide. If deforestation keeps on happening‚ our oxygen supply will also deplete. That’s one thing I can guarantee. It means that we won’t have enough air to breathe with and it will

cats. They had many pests that the cats helped eliminate. Plus the cats were so important to the Egyptian people that they would be mummified with different materials. So basically the Ancient Egyptians domesticated and mummified cats. The Domestication of Cats The Egyptians were possibly the first to domesticate cats. But the question is how did they do it? According to J. Hill‚ “Egyptians learned that the wild cats preyed on scavengers and began to leave out food (such as fish heads) to

The uses of plants in developing and producing vaccines For thousands of years‚ society has been brought to the brink of disaster thanks to the spread of resilient diseases and the plague of hardy viruses. However‚ humans have been aware for just as long of medicinal defence mechanisms against these ailments. The ancient Egyptians and Romans‚ as well as the primitive islander and Aboriginal communities‚ knew that certain herbaceous matter could help heal the wounded and sick. In more recent times

TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season

Plant Cell Plant cells have many different parts that are need to work together and function as a whole. These parts are the cell membrane which can be compared to a "Condom" due to the fact that is a very thin protective layer that lets certain substances to pass through. Cell wall is a thicker rougher membrane‚ which gives the plant most of its structure and support‚ the cell wall also bond with other cell walls to form the structure of the plant. Centrosome may be also referred to as the

A world without plants Plants; probably the most ignored organism on this planet. People walk past plant and cut them down but nobody ever thinks about what they do for us‚ what the world would be if there was never any plants or photosynthetic organisms. If the world never had these organisms the world would be a desolate place. There would be no oxygen‚ atmosphere‚ or food. We inhale air unconsciously every day. By taking in air‚ we absorb oxygen and discharge carbon dioxide in the process of

Plants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have abtained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato‚ farmers will pick the potatoes and cut
