Biology Excursion Question Using data collected on field trip and two named animals, explain the relationship between the distribution and abundance of these two organisms and the abiotic features of the rock platform. There is a close relationship between the abundance and the distribution of organisms living amongst the long reef platform. Abiotic features such as temperature range, salinity, Ph. levels, turbidity, water availability effect the distribution and abundance of aquatic sea creatures living in the area. Some of the organisms such as Tesseropora Roseas (Barnacles) and Knobbly Winks have different adaptations, which allow them to survive in these harsh conditions.
The Importance of Shapes Fitting Together in Cells and Organisms Lots of molecules in cells and organisms fit together with other molecules that have complimentary shapes in order to work and serve their purpose. An example of a type of molecule that does this is enzymes. Enzymes are proteins that speed up metabolic reactions, from the digestion of food to the synthesis of DNA, and so are very important. One of two models that demonstrate how enzymes work is the ‘lock and key’ model, in which the active site of an enzyme has a complimentary shape to a specific substrate and they fit together perfectly (like a key in a lock, hence the name) to form an enzyme-substrate complex. The other model is the ‘induced fit’ model, which describes the formation of an enzyme-substrate complex as a result of the enzyme’s active site adapting its shape to fit with the substrate (almost like a glove) to allow for
Properties of Water Property | Importance | Examples | Solvent | Metabolic processes in all organisms rely on chemicals being able to react together in solution. | 70-95% of cytoplasm is water. Dissolved chemicals take part in processes such as respiration and photosynthesis in living organisms. | Liquid | The movement of material around organisms both in cells and on a large scale in multicellular organisms requires a liquid transport medium. | Blood in animals and the vascular tissues in plants use water as a liquid transport medium.
The Effects of Temperature on the Swimming Behavior of Daphnia Introduction: Plankton play a large role in the ecosystem. Plankton are aquatic organisms that exist in innumerable different regions of aquatic environments. They can be utilized as a food source for other planktons, large aquatic animals, and other animals. Since they are at the pedestal of the food chain, they are important since they fill the base of the ecosystems they exist in. Many zooplanktons are also ectothermic which means temperature can highly affect metabolism and growth (Jalal et al., 2013).
Biodiversity, known as the variety of all life forms on Earth, from the tiniest bugs living in the soil, to the birds in your garden, the plants they feed from, and the biggest sharks in the sea, are indeed the basis of our human existence and our life support system. The ecosystem depends on biodiversity to do a wide variety of processes that are fundamental to humans and life in general, such as regulating climatic processes, breaking down wastes and recycling nutrients, filtering and purifying water, buffering against flooding, maintaining soil fertility, purifying air, and providing natural resources such as wood, textiles, and of course food. The biological diversity we enjoy today is the product of millions of years of evolution, and
Health and social Unit 4: Development through life stages Growth Growth is a process everything goes through, from animals to vegetables to the human body. Throughout different life stages the human body grows physically over the years. Growth starts from being a baby to a child to adolescence through to adulthood; the body goes through all sorts of different body sizes and changes in appearances. A person’s growth depends on the environment they live in and genetics can also determine the pace of growth. Diet and nutrition are important factors the body requires to grow.
Nature has selected advantageous variations from the mutations and new gene combo's produced at each human understanding. The genes selected during our ancestors history provide strong capacity to learn and adapt to life in varied environments. 2. Identify several methods used to study the brain and give a significant finding
Evolution forces adaptations to changes in environmental conditions in a population. The diversity of life on earth reflects the wide variety of adaptations necessary and suggests that environmental conditions have varied widely over the life of the earth. 3. An ecological niche is a species’ way of life or its functional role in a community. Everything that affects its survival and reproduction (temperature tolerance, water needs, space needs, interactions with other organisms, etc.)
Chad Walker 1/25/12 Bio 151 MW 4:00-5:15 Biological Adaptation Assignment Biological adaptation is necessary for a species to increase their fitness in an environment. As organisms face different environmental challenges they must be able to develop different phenotypic traits over time to respond to the conditions. One example of an organism that can adapt to different extreme environments would be the bull shark. Bull sharks may seem like a typical shark because they are most often seen in marine habitats, but they can survive elsewhere. What I find peculiar about the bull shark is its ability to live in both marine habitats and freshwater habitats.
The following topics are addressed: evolution, sound production, sound reception, feeding, locomotion, buoyancy control, thermoregulation, cognition, and behavior. A variety of approaches and techniques are used to examine and characterize these adaptations, ranging from dissection, to histology, to electron microscopy, to two-dimensional (2D) and 3D computerized tomography, to experimental field tests of function. The articles in this issue are a blend of literature review and new, hypothesis-driven anatomical research, which highlight the special nature of anatomical form and function in aquatic mammals that enables their exquisite adaptation for life in such a challenging environment.
