Rainforests February 18th‚ 2013 Mr. Zanardo AJ D’Orazio CGF 3M Grade 11 Rainforests are the oldest living ecosystems on earth. They only cover about 6% of the Earth surface but they contain more than half of the world’s animal and plant species. Rainforests are described as a tall but dense jungle. It is called a “rain” forest because of the high amount of rainfall it gets per year. There are two different types of rainforests Tropical and Temperate. A tropical rainforest is located

Overall‚ through this lab provided a vast amount of knowledge regarding processing techniques‚ and allowed understanding regarding the principles of preparation that preserves the color‚ texture‚ flavour and nutrient value of vegetables. Each station participated in a different method of cooking‚ and through observations it is easy to see the effect of pH on pigment and texture of various vegetables‚ the effect that cooking procedures has on various pigments

Plants’ root colonisation by AMF has been demonstrated by numerous authors‚ in particularly Glomus spp. including R. iregularris formerly G. intradices (Chen et al. 2007; Bidondo et al. 2011; Calvo-Polanco et al. 2014; Liu et al. 2015). In this study‚ root colonisation was observed for all the studied treatments except for the control. Colonisation was not expected for the control since the soil was sterilised and this was obtained as the result (Fig. 1 and 2). Based on the results‚ the frequency

the population size of many species (McGinley‚ 2008). Brassica rapa plants are model organisms to study because of their rapid-cycling‚ small genome sizes and short life cycles. Brassica rapa also known as “fast plants”‚ because they can grow into adults in the span of seven weeks‚ is an ideal species to study competition (Miller‚ 1995). These Brassica rapa plants will compete for space to grow‚ sunlight‚ water‚ and soil nutrients so that they can live. This experiment that we are doing is important

multiplication of such hybrids by maintaining their hybrid vigour. To reduce mortality and release the stress upon transplantation as well as to provide fast growth‚ establishment of ectomycorrhizae on micropropagated plantlets is suggested as these help in nutrients uptake and reduce environmental stresses. Therefore‚ the present work was undertaken with the objective of studying interaction of Laccaria laccata‚ an ectomycorrhizal fungus‚ with micropropagated plantlet of the hybrid under in-vitro conditions

growth for each colony. This could be the result of the mutual symbiotic relationship that bacteria share with hairy cap moss‚ a greater source of nutrients available for bacteria in hairy cap moss in soil than in lichen on bare rock‚ or due to the temperature differences between the two sites being sampled. Introduction Lichen‚ or Cladonia sp.‚ is a plant that is made up of algae‚ bacteria and fungi. Lichen is a composite symbiotic organism that thrives in regions that have extreme temperatures‚

Chapter 7: Living in the Environment: environmental factors and their influence Questions Introduction 1. Why is a Polar bear found living in a cold icy place and a fish found living in water‚ but not in other environments? Because it is their habitat in which they are adapted to. It has certain adaptations to allow it to survive in that environment and resources are available in the environment. 2. Give the definitions for the following words (the glossary at the back of the book may help

“The process in green plants and certain other organisms by which carbohydrates are synthesized from carbon dioxide and water using light as an energy source. Most forms of photosynthesis release oxygen as a byproduct” . The main job of photosynthesis is to convert CO2‚ H20‚ and light into sugar‚ or food‚ and oxygen. Now‚ to create these products‚ two processes have to occur: light reactions and the Calvin cycle. Light reactions occur in the thylakoid‚ C4 plants and C3 plants also exist. Methods

Aquaculture‚ also known as aqua farming‚ is the farming of aquatic organisms such as fish‚ crustaceans‚ mollusks and aquatic plants. Tilapia is one of the most important fish in aquaculture. Tilapias are also among the easiest and most profitable fish to farm. This is due to their diets and rapid growth. The University of the Virgin Islands focuses on cage culture of tilapia watershed ponds that had multiple uses for livestock watering and crop production. I went to the farm store and I saw three
