The sweet potato industry, although a high value industry, is becoming increasingly competitive. This underlines the importance of efficiency in minimising the loss of valuable soil. Large amounts of rainfall can result in the loss of soil on cultivated farmland. The loss of soil does not just affect the farmers it also affects the community The aim of the project was to increase awareness of soil health and to develop the best soil management practices for the Cudgen plateau. Figure [ 2 ] Water Way On the Cudgen Plateau, three adjoining landholders implemented soil conservation measures and strategies.
As the insects died on or around the plant, they enriched the soil with organic matter. Within a few years, the lupine patches became biological hotspots facilitating the growth of other plant species and attracting numerous insects, birds, and small mammals. The flourishing of life on the Pumice Plain of Mount St. Helens today may have begun with that lone lupine. Crisafulli said that it was the lupine wildflowers that taught him one of the key lessons of succession: the importance of
By using the genes from two bacteria producing organisms such as Alcaligenes Eutrophus, they could insert them into cress plants with the aim of these plants producing the PHB. This process worked and the plants and some of their offspring produced around 14% of the dry weight as PHB. Although this is not as high yielding as when it is produced in the petri dishes, it is a much more economically viable method of production and hence would give a much more substantial impact to society. Chemically PHB is from a group of biopolymers known as the polyhyroxyalkanoates. Figure 1 below shows other examples of biopolymers in
The shape of a cell is related to its function because of the adaptations made throughout time to make the cell as efficient as it can be. There are two types of cells, eukaryotic cells, which are generally plant and animal cells and prokaryotic cells which relate to bacteria and fungi, which undergo asexual production. Plants are anchored into the ground by roots. The function of roots is the transportation of water and mineral ions from the soil into the xylem to transport around the plant. The roots have an outer layer of cells called root hair cells that have a specific shape that makes the uptake of water and mineral ions more efficient.
The results showed that the increasing of the density leads to a decrease in the biomass of plants and that the experimental groups are not much different than the control groups. This shows that an environment can work to stabilize itself without human interruptions. Plants can ensure they don’t overpopulate an area by self-thinning and species can survive with predators using the environment they were given. Introduction Competition for resources is seen in all species and environments around the world. Since the Earth’s natural resources are limited, it necessary for species of all kingdoms to fight in order to gain enough nutrients in order to not only live but thrive and go on to produce future generations.
This hypothesis is supported by what is known about termite biology. The termite that will be used is Reticulitermes flavipes of the worker class. Worker termites are the most abundant in a termite colony and primarily responsible for the foraging and collection of wood for feeding the upper termite castes. These worker termites are blind and can only perceive changes in light intensity. It is therefore assumed that any color change in the wood will not affect worker termite foraging patterns.
3) What does the taproot system do? Often stores organic nutrients that the plant consumes during flowering and fruit production. 4) Why are root crops such as carrots, turnips, and sugar beets harvested before they flower? Because the taproot system stores organic nutrients in the root part. 5) What is the system where no roots stand out as the main one?
Disease Yersinia pestis The Plague Jesus Urquijo Biology 113 Lab March 18, 2013 Microbes are what make the world what it is today. They are found in nearly every environment on earth. Each species has its own way of getting nutrients and adapting to its environment, such as pH, aerobic and anaerobic conditions, and enzymes that are essential for optimum living. The majority of bacteria living on earth are harmless if not beneficial to the human race, but those few microbes that are harmful to humans are those that cause disease. They are referred to as pathogens and need to be observed so we can prevent the spreading of disease caused by those particular microbes.

Why Do Autumn Leaves Change Colors? Eliena Mahgerefteh Autumn, a time distinct for smells of home cooked food and parks filled with crunchy orange sugar maple and yellow black maples trees. How come this time of year is we see such beautiful changes in our scenery and wander why it is that leaves that are normally green in the spring and summer transform to colors of vibrant reds, oranges, and yellows? First off, it is important to note that leaves are important to the health of trees for they are nature’s food factories. Plants take in water through their roots and carbon dioxide from the air.
