Observation of Digestive and Circulatory System Introduction/Background: This week’s lab is about digestion and the circulatory system. Students will be learning about the different types of digestion and circulatory systems for different types of animals. Students will learn not only about the mechanical and chemical components of digestion‚ but also the complete and incomplete digestions. The lab will also teach the open and closed‚ single and double‚ circulation patterns. Several different models

Introduction to sexual reproduction in humans Reproduction is the process by which humans gives rise to new individuals. Sexual reproduction is the process that involves the fusion of two gametes‚ sperm (male gamete) and egg (female gamete). In human these gametes are produced in different sexes‚ the male and female. Reproduction in humans is performed by reproductive systems‚ the male and female reproductive systems. The main organs of male reproductive system are testis and gonads and of female

Define population - Consists of all the individuals of a species that live in a specific geographical area and can interbreed. 2. Define natural selection. - The differential rate of reproduction. 3. Explain how gradualism and punctuated equilibrium relate to evolution. - Both involve the species evolving either over a long period of time or rapidly. 4. What does a paleontologist do? - Scientists

largest phylum in the animal kingdom‚ exceeding in number all the other Phyla combined. The characteristic tough exoskeleton and jointed limbs are superimposed in a segmental body plan that reflects the evolution of arthropods from ancestors of the annelid worm. Insects‚ arachnids‚ myriapods and crustaceans are the major groups in this phylum (Nichols). Insects are the largest of this phylum and make up the largest class of all organisms and are recognized by taxonomist to have nearly one million

These resources are looked at as infinite‚ although this is not actually the case. Each time one person does something to pollute or use these types of resources‚ it affects the whole of society. This is the

Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population
