Living things are based on a universal genetic code a) All organisms sore the complex information they need to live‚ grow and reproduce in a genetic code written in a molecule called DNA. b) That information is copied and passed from parent to offspring c) With a few minor variations‚ life’s genetic code is almost identical in every organism on Earth 2. Living things grow and develop a) Every organism has a particular pattern of growth and development b) During development‚

and nonliving organisms and consists of particular physical components that allow each to interact with one another. All these organisms are designed to accomplish the common purpose of processing nutrients‚ discarding wastes‚ responding to environmental stimuli‚ and reproducing within the particular environment. For example‚ organisms are inhabited in a community. The costal community is comprised of pelicans that eat the fish in the ocean. In addition‚ a diverse range of organisms survive together

part of my experiment‚ which involved the EMB and MSA plates. My lab partner and I were required to take a marker and on the back of our EMB and MSA plates section each plate into four quarters. We then labeled each quadrant of both plates with one organism that we were given at the beginning of the lab. Next we labeled our plates with our names and lab times. We were then prepared to inoculate our plates. Starting with the EMB plate‚ I first sterilized my inoculation loop and dipped it into the test-tube

5. 1. 1 Define species‚ habitat‚ population‚ community‚ ecosystem‚ and ecology. Species – A species is a group of organisms with similar characteristics‚ which can interbreed and produce viable‚ fertile offspring. Habitat – A habitat is the environment in which a species normally lives or the location of a living organism. Population – A population is a group of organisms of the same species‚ who live in the same area at the same time. Community – A community is a group of populations

species like dinosaurs as well. 3. Natural selection acts on genetic differences within a population to cause evolution. Individuals do not evolve. 4. Evolution occurs constantly‚ without end; there is no endpoint in evolution. Question 3 One organism gets larger as it passes through its life cycle. This is an example of __________. 1. reproduction 2. development 3. growth Question 4 Imagine you have a peanut butter sandwich in front of you. The sandwich is an example of _______. 1. energy

building up of molecules in order to make energy available for needed functions. Third is motility. Motility is the ability of an organism to self-move under its own power. Fourth is Responsiveness. Responsiveness is the organism’s ability to react to its environment and surroundings. Fifth is reproduction. Reproduction is an organisms ability to create a like organism.

Questions: Summarize your amino acid comparison in paragraph form. To guide your summary‚ reflect on the following questions. 1. What does it mean when scientists say that living organisms share a universal genetic code? When scientists say that living organisms share a universal genetic code it means the all living organisms have some traits in common but are not the exact same. 2. How does a universal genetic code relate to the hypotheses about the origin of life on Earth? The universal genetic code

unrelated species. Usually this is done in order to get one organism to produce proteins‚ which it would not naturally produce. The genes taken from one species‚ which code for a particular protein‚ are put into cells of another species‚ using a vector. This can result in the cells producing the desired protein. It is used for producing proteins which can be used by humans‚ such as insulin for diabetics and is also used to make organisms better at surviving‚ for example genetically modifying a plant

guessed‚ or already knew‚ and may not be all that interested to know‚ anyway). Microbiology is actually made up of several sub-disciplines. Microbiology‚ one of the fastest growing areas of science‚ is the study of organisms so small that they must be viewed with a microscope. These organisms are primarily bacteria‚ yeasts‚ molds‚ and viruses. Many of the most important scientific discoveries of recent years have been made by microbiologists: since 1910‚ one-third of the Nobel Prizes in medicine and
