era, about 10.000 years ago, nomadic groups were know scavenge, hunt, fish, and gather plants in an neverending search for food. It all ended when they learned how to plant native grasses (grains) and developed agriculture. The latter requires a commitment to land and definitely grants a steady food supply, enabling people to form permanent settlements, which was a first at that point in time. The Cannabis plant often came in contact with Neolithic bands, as it invaded the fertile clearings (such

ife began on earth about 3.5 to 4 billion years ago, since then it has evolved and flourished. Within the kingdom Animalia, it alone consists of 35 phyla. Two of which are Onychophora and Annelida. Onychophora are believed to be a possible link between two phylums of Annelids and Arthropods as it carries characteristics of both groups. This essay seeks to compare and contrast between the earthworms from phylum Annelida and the velvet worms from phylum Onychophora. Internal Velvet worms and earthworms

can add character to our living space. While this works in most cases but majority of times, the place only needs a burst of fresh color. This can easily be handled by painting the place, adding a few character pieces and a pot of a bright flowering plant. Hence you can save hundreds of dollars by putting in just a little effort. Container gardening is not simply limited to indoor decorative purposes. In addition, it can be quite practical as well. We often find, elderly people complaining about the

Jimi Underwood 10.24.2014 PLNT 5412 Proposal for Blue Grama Breeding Program Introduction Recently, there has been a growing interest in the use of North American native grasses for the use as a turfgrass and as ornamental grass. Multiple reasons exist for this interest; among them are the perceived lack of invasiveness (as compared to other introduced species), their existing adaptation to the climatic conditions of specific locations, and even the maintenance and storage of the germplasm (Watkins

Two million years ago, there were three killer on the top of the food chain, they were Titan birds, saber-toothed tigers and wolves. The titan birds and saber-toothed tigers are much bigger and stronger than wolves, but they disappeared in this world. They don’t have social, they live alone. They can’t protect their children when they hunt, and they don’t know how to save food. Wolves always fight as a team. Their million years experience tells them 5-10 wolves is the best number in a team. They

“Mystery Compound Found to Kill Coho Salmon”, an article by Christopher Dunagan, emphasizes the negative impact of stormwater runoff on different types of fish in the river, specifically coho salmon. It’s proven by scientists that polluted stormwater runoff contains pollutants that kill coho salmon. Pre-spawn mortality in female coho salmon was noticed in rivers when high numbers died before giving birth, especially during times right after a rush of fresh stormwater. Scientists concluded that toxic

TITLE - How does plant growth get affected when it’s provided a different type of water? Independent Variable - Weeks Dependent Variable - Plant’s growth in Meters PURPOSE - The purpose of the lab was to test plant’s growth level when it was given different sources of water for 3 weeks. BACKGROUND INFORMATION - Water is affecting our nature, humans, all living organisms because water can sometimes be toxic to anyone and mostly to plants. Plants need sufficient water that is good quality and

was to invade the non-native plants on the sidewalk. One of the stewards started showing me what kinds of plants we are invade and teach me how to invade them. There were two main types of non-native plants in our working area, which were ivy and blackberry. Those little individuals grow fast, widely and have really bad affects to the native plants and even the environment system of the area. So it is better to remove them with their roots in order to keep the plants in balance in this area.

According to our results, there was no significant difference in the height and growth of Wisconsin Fast Plants (Brassica rapa) housed in different soil types. This finding contradicted our expectations since soil is one of the main variables in growth of a plant organism. And we measured the height and growth because impacts on plant growth is a widely used indicator of resistance or sensitivity to the plants environment (Black, 2007). In our planning, we expected that the regular potting soil would result

Many extinct species—from the passenger pigeon to the woolly mammoth—might now be reclassified as "bodily, but not genetically, extinct." They're dead, but their DNA is recoverable from museum specimens and fossils, even those up to 200,000 years old. Thanks to new developments in genetic technology, that DNA may eventually bring the animals back to life. Only species whose DNA is too old to be recovered, such as dinosaurs, are the ones to consider totally extinct, bodily and genetically. Useful
