DNA is the biomolecule that provides the information for that organism. Which of the following statements about DNA is CORRECT? ……….. All cells in an organism have the same DNA‚ but differently expressed‚ providing specific cellular functions. Which of the following molecules is not found in RNA? ………… Thymine. Which of the following types of molecule would be most abundant in a typical animal cell? ‚‚……… Water. While studying the biochemistry of a species of plant found in alpine bogs‚ a biologist

things or organisms provide each other with substances necessary for life‚ and a proper balance between plants and animals is needed to maintain life (1‚ p.246d). AEcology is the study of interrelationships of organisms to one another and to the environment@ (2‚ p.121). AThe word AEcology@ comes from the Greek words Oikos - house‚ and Logos - the way a subject is spoken about or treated. Ecology is a subject that tells about the Ahouses@ of living things‚ in other words the study of how organisms interact

• PHOTOSYNTHESIS: • Is a process used by plants and other organisms to use light energy usually the sun ‚ to make sugar molecules. • The result of photosynthesis is sugar which is called CARBOHYDRATES PRODUCERS‚ CONSUMERS‚ DECOMPOSERS • Producers: is an organism that makes its own food. • Consumers: is organisms that get their energy by eating other organisms. • Decomposers: there organisms that get there food by breaking down organisms. • Cellular Respiration: The process of breaking down food

Abstract: : The purpose of studying the biological organisms in the Mpenjati estuary-beach system is to distinguish between organisms and estimate diversity within the estuary found at different locations along the estuary-beach profile in accordance with factors affecting the daily routines of these marine life and other aspects in which these organisms concur with. The organisms found in these waters play an important role in the ecosystems they function in therefore it is imperative to seek a

chemical processes occur in various living organisms. In biology you learn about living organisms and their composition. Organisms are alive because of chemistry. Chemistry is the one science in which all the other sciences are based. No matter what you are studying in biology‚ be it plants‚ animals‚ microbiology‚ etc.‚ in order to fully understand it‚ you need to be able to understand the chemical reactions that need to take place in order for whatever organism you are studying to have life.

The regulation of internal environment by animals: homoeostasis All living organisms have ideal environmental conditions for survival and reproduction. Animals have an internal environment as well as the external environment they are living in. If their internal environment deviates too much from the ideal they may experience reduced function or even die. Homoeostasis is the adapted ability of an organism to regulate its internal environment to deal with changes in the external environment. (Raven

which comprise the vast majority of any organism’s gene repertoire‚ are common between Archaea and Bacteria. In terms of their cell structures‚ Archaea are indistinguishable from Gram-positive bacteria. Within prokaryotes‚ only these two groups of organisms are bounded by a single unit lipid membrane‚ and they generally contain a thick sacculus of varying chemical composition. Some Archaea also show positive Gram staining and a few of them‚ similar to certain Gram-positive bacteria‚ do not contain any
