Terrestrial and aquatic mammals, although from different taxa and completely different environments, communicate over long distance in similar ways, but of course have differences since they evolved from different ancestors. Specific to this paper, elephants and whales are discussed; the way their ears, external or internal, are structures and how each section of their ears function to aid in the process of hearing frequencies from conspecifics. Elephants not only use their large ears to…

According to Lucretius in On The Nature Of Things, the power of nature and science relied on arbitrary mixtures and “indestructible particles” to create life and earthly systems in an limitless world. On the contrary, Darwin explores a variety of topics that portray life as being dependent on gradual changes, variations, competition, deity beliefs, morals, and natural selection. He asserts, “Natural selection, as we shall hereafter see, is a power incessantly ready for action” (Darwin page 108).…

An aquatic ecosystem is a community of organisms that live within a body of water such as freshwater system or a saltwater system. The application of understanding aquatic ecosystems is how species adapt and inhabit a specific body of water that they reside in and the role that different water systems play in the survival of these various species. It is also important to understand the biodiversity within aquatic ecosystems to recognize why and how a wide range of diverse species can maintain a…

auditory masking leading to cochlear damage, change in behavior, altered metabolisms and malfunctioning health and ecosystems. This noise pollution can increase the stress of animals and interfere with the sound-based orientation. Biotic and abiotic sounds are the two components of underwater environment produced by fish and mammals in order to communicate and orient. Acoustic masking is one of the main effects of noise pollutions on marine animals. The noise from boating and shipping has an…

the largest coral reef in the world. It is sometimes referred to as the largest structure built by living creatures. (2) Something that I would call the Burj Khalifa of the animals. Key Abiotic Components of the Great Barrier Reef: An abiotic factor is something non living that affects the biotic factors of an…

1. Describe two scientific theories relating to the evolution of the chemicals of life A scientific theory is an explanation based on observations, reasoning and experimentations, especially one that has been tested and confirmed as a general principle helping to understand, explain and predict natural phenomena. A scientific theory must be based on careful and rational examinations of the facts. There are 5 major theories that account to the evolution and origins of chemicals of life. However…

dehydrogenase activity of the soil and its activity is an indicator for microbial activity of the soil. Thus, soil fungi concentrate in the subsoil and play a major role in organic matter build up by decomposition and degradation of resistant organic component such as cellulose, lignin and chitin. They also participate in the stabilization of soil aggregates due to their filamentous nature and thus may prevent soil erosion (Banda et al.,…

i. Enzymes are macromolecules that increase chemical reactions without being consumed in the reaction. They do this by lowering the activation energy (the amount of energy that reactants need to absorb in order for a chemical reaction to take place). Every enzyme has a substrate with a unique shape and structure for it to bind to. Denaturation of proteins (when a protein unravels and becomes inactive), and change in the shape of the enzyme or substrate all influence the activity and…

Adverse effects have a significant impact on the patient’s recovery while being in hospital, especially hospital acquired infection. The aim of this essay is to critically evaluate adverse events within a hospital as well as examining nursing strategies to prevent hospital acquired infection. It will be discussed what an adverse event is, and the prevalence of hospital acquired infections within Australian hospitals. Identifying the effects on the patient, family members and the healthcare…

The importance of biodiversity Importance of biodiversity is a fairly new topic that has been gaining considerable attention as the awareness of the significance of natural ecosystems and environments increases. There is thus a new approach to conserve our environment as opposed to merely utilize and diminish it (Silvert 2006, de Vere 2008, Malhotra 2012). This was brought to attention in the 1900s by literature such as “Our Plundered Planet” by Fairfield Osborn. In the 1960s there were many…
