What is the ultimate source of energy for all organisms on this planet? The ultimate source of energy is the sun. 2. List the biomes of the Earth. A biome is a large naturally occurring community of flora and fauna occupying a major habitat (a forest). The biomes of the Earth include the desert‚ the

that question‚ they have come up with two contradicting yet plausible theories‚ Creation and Evolution. The theory of Creation states that an intelligent being designed each organism. On the other hand‚ the theory of Evolution states that some form of stimuli sparked one of the earliest forms of life and that every single organism living today evolved from it. Starting with the evidence and the criticism for the theory of Evolution‚ this paper will provide the main arguments and criticism for both theories

tissue in living organisms is functionally organized‚ and because this organization is the product of evolution by natural selection‚ a major presumption of evolutionary psychology is that the brain‚ too‚ is functionally organized‚ and best understood in evolutionary perspective. It is clear that the body is composed of a very large number of parts‚ and that each part is highly specialized to perform a specific function in service of the survival and reproduction of the organism. Using the body as

While the definition of living organisms must be adapted‚ the majority of evidence leads to the classification of viruses as living organisms. Viruses are composed of a nucleic acid core‚ a protein capsid‚ and occasionally a membraneous envelope. The nucleic acid core is composed of either DNA or in the case of retroviruses‚ RNA

Out of the two organisms we looked at‚ my favorite is the Paramecium. Paramecium are grouped with protists because‚ like all protists‚ they’re single celled organisms. Paramecium fall under the Protozoa Phylum in the Protist Kingdom. If an organism is in the Protozoa Phylum category‚ that means it is a small microscopic organism‚ which Paramecium are as they can only be seen under a microscope‚ and it reproduces by binary fission (splitting in half‚ becoming two new organisms)‚ which Paramecium do

genotype and phenotype‚ and describe how they are related. Genotype is the genetic make-up‚ the inheritable information‚ which comprises an individual organism. It is the code that is copied in reproduction and is passed from 1 generation to the next. It serves as the main guide in the growth‚ development and maintenance of a living organism; it also controls the formation of certain proteins and regulation of metabolism and synthesis. Alleles are alternative forms of a gene and genotype refer

concerned with the study of organisms and their habitats. This includes the interdependence of various populations‚ their impact on each other and their surroundings‚ the effect of the surroundings on their behaviour‚ as well as the ways in which the organisms and the environment change in response to each other. A pond and its inhabitants provide a good example of these interrelationships. A pond contains: a. soil consisting of rock‚ minerals and dead remains of organisms b. water with minerals c.

is a field of applied biology that involves the use of living organisms and bioprocesses in engineering‚ technology‚ medicine and other fields requiring bioproducts. Biotechnology also utilizes these products for manufacturing purpose. Modern use of similar terms includes genetic engineering as well as cell and tissue culture technologies. The concept encompasses a wide range of procedures (and history) for modifying living organisms according to human purposes — going back to domestication of animals
