Biology synoptic essay
A synoptic essay in biology is a paper that discusses the broad themes and connections between biological concepts. It requires the integration of ideas from multiple sources, such as lectures, readings, and lab experiences, and the ability to apply these ideas to new situations or problems.
One of the central themes in biology is the concept of evolution. Evolution refers to the process by which populations of organisms change over time in response to selective pressures in their environment. This process is driven by the mechanisms of natural selection and genetic variation, which result in the survival and reproduction of certain individuals and the extinction of others. Evolution is a fundamental principle that underlies the diversity of life on Earth and the adaptation of species to their environment.
Another important theme in biology is the concept of homeostasis, which refers to the ability of an organism to maintain a stable internal environment in the face of changing external conditions. Homeostasis is achieved through the operation of various physiological systems, such as the circulatory, respiratory, and nervous systems, which work together to maintain a balanced state within the organism. Disruptions to homeostasis can result in illness or death, highlighting the importance of maintaining a healthy internal environment.
Another key theme in biology is the concept of energy flow. All living organisms require a constant input of energy in order to survive and reproduce. This energy is obtained through the process of metabolism, which involves the conversion of chemical energy stored in organic molecules into forms that can be used by cells. The flow of energy through an ecosystem is driven by the transfer of energy from one trophic level to another, with primary producers at the base of the food chain capturing energy from the sun or inorganic sources, and consumers higher up the chain obtaining energy by consuming these producers or other consumers.
A final theme in biology is the concept of ecosystems and the interactions between living and nonliving components. An ecosystem is a community of living and nonliving things that interact with one another and with the environment. These interactions can be complex and involve the transfer of energy, matter, and information between different components of the ecosystem. The health and stability of an ecosystem depends on the balance of these interactions, and disruptions to this balance can have significant impacts on the ecosystem and the organisms that depend on it.
In conclusion, a synoptic essay in biology requires a broad understanding of the themes and connections that underpin the study of life. These themes include evolution, homeostasis, energy flow, and ecosystems, and they provide a framework for understanding the diverse and complex processes that occur in the natural world.

The essay can be really boring when it does not engage the readers in the argument. Seasonal changes will render conclusions drawn in winter for example, less reliable in summer when other organisms proliferate and the Copyright © Dr Robert Mitchell 2010 Essay 19: Perform a critical analysis of the methods used to collect biological data competitions and interactions between the plants and animals are completely different. The dense number of carbon to carbon and carbon to hydrogen bonds in lipids makes these molecules energy rich and so they can act as useful fuels. The information can them be processed by the brain. The more the points and the wider the topic the more pages the article will have and so will be the number of the paragraphs. Another type of lipid is a phospholipid.

While farming and deforestation reduces diversity, allowing areas to recover and a natural succession to take place will enhance it. Even identical twins with the same genotype, can vary due to subtle differences in environmental factors that influence them in different ways. The way in which we live our lives can have a profound effect on the physiological processes which take place in our bodies. One key factor in plants for example is the availability of key nutrients or energy. The bases are arranged in triplets, each triplet codon coding for a specific amino acid in a polypeptide chain. In leaves, photosynthesis involves the photolysis of water, a process that involves the attachment of two electrons to a magnesium ion in chlorophyll and the production of hydrogen ions from the breakdown of water.

The tissue is composed of cells containing actin and myosin filaments which move relative to each other to contract a sarcomere. Since all living organisms respire, the carbon dioxide removed by plants for photosynthesis is constantly replaced. However, a good way to appreciate how to write a good essay in biology is to follow the structure as outlined below. The antigenic variability that results from the changes in the gene sequence will allow some of these forms to evade the host immune systems of the animals they infect, increasing the incidence of disease. Quantifying habitats and ecological systems pose unique difficulties. This alters the control and regulation of the cells.

They are also a rich source of unsaturated fats which act as the energy source for the germinating seed. The T-helper cell had released cytokines which bound to specific receptors of the cell surface membrane of the B cell. Enzymes are globular proteins which have a specific tertiary structure that has a complementary shape to that of a specific substrate molecule. This is one way scientists are able to classify the relationships between species in order to calculate species diversity index within an environment to facilitate studies of the interactions between organisms, for example during succession. However the pace of environmental change is faster than many species can adapt and so, on balance, the diversity index of environments will likely fall.

In the coronary artery these can lead to a reduced blood supply to the heart resulting in the death of muscle cells through lack of oxygen, resulting in myocardial infarction. The process of mitosis separates the two copies of each chromosome. The glucose or starch can be used as an energy source directly by the plants, or indirectly by animals which consume, digest, absorb and assimilate the sugars. A fuel is any substance that releases energy in a useful form when reacted with oxygen. The biological importance of water. Hydrophilic channel proteins are embedded in the bilayer which provides a route by which polar substances can enter, either down a concentration gradient by facilitated diffusion or against a concentration gradient by active transport.
Water is also pulled up by the cohesion-tension mechanism. Copyright © Dr Robert Mitchell 2010 Essay 13: Genes and diversity Through this process of natural selection, the genes and their alleles are helping the populations to adapt to their environment, a process that can reduce diversity in the gene pool as those less adapted members die out. In animals, the receptor surface is the retina of the eye which comprises the receptor cells, rods and cones. In the bilayer, the hydrophobic tails can align producing a structure with hydrophilic properties on either side which can interact with the aqueous environment inside and outside the cell. This is an important process as it not only introduces genetic variations into a population, but also allows the restoration of the diploid number of chromosomes on fertilisation. There are many cycles in biology including cycles that occur inside organisms such as the cardiac cycle, calvin cycle and the krebs cycle.
How the digestive system to mammals is suited tort digestion and absorption. Glucose is a hydrophilic monosaccharide and cannot therefore diffuse directly through the hydrophobic membrane. The process of protein synthesis, or translation can now begin. For example, the bacteria Vibrium cholerae releases a protein toxin that opens chloride ion channels in the large intestine causing loss of chloride from epithelial cells, and loss of large volumes of water as diarrhoea and chronic dehydration. For example it may happen by chance that five students chosen are taller than the average and so a comparison to a small group of other students may prove invalid. The products have a different shape and can no longer remain bound. The properties and importance of enzymes in plants and animals.
. They should be regarded as a bare minimum and consequently should be supplemented by class notes and independent notes following your own extensive background reading! Firstly to transport dissolved oxygen, hormones, nutrients, salts, enzymes and urea to cells located around various places within the body, whilst at the same time eliminating any waste products such as carbon dioxide and water. Human activities such as deforestation and the burning of fossil fuels to provide energy have resulted in an increase in atmospheric carbon dioxide concentrations. Some of Copyright © Dr Robert Mitchell 2010 Essay 15: The impact of human activities on the diversity of plants and animals these individuals may have alleles that make them smaller and darker than others which may now be a benefit. Less and less energy is available to the next trophic level as more and more is lost through movement, heat and excretion. The B cells are another class of lymphocyte involved in humoral immunity. Phagocytosis of pathogens eventually leads to activation of B-cells which divide by mitosis forming clones that differentiate to form plasma cells.
