Excretory System Read Kraus pages 248 to 250. List the many different?functions of the skin: There are four different functions for the skin. The skin acts as a protective organ, meaning that the skin provides defense from mechanical injury and bacterial infections. How does the liver assist with excretion of nitrogenous?waste? The liver assists with the excretion of nitrogen waste. When humans eat food containing a surplus in protein, an excess of amino acid forms. Amino acid contains nitrogen. If the protein is not used to repair the body or help it grow, it is changed in the liver into nitrogenous waste and is secreted. This is why doctors warn about the excess consumption of foods like meat, fish, and eggs.

M2A1 Eric Mackey For this assignment, identify the biome in which you live. Using the readings for this module, the Argosy University online library resources, and the Internet, respond to the following: Explain how humans have impacted the biome in which you live. List the types of environmental damage that have been caused and the species that have been impacted. Describe the major pollution issues for your biome, and elaborate on the sources of this pollution. List any species that have become extinct in this biome. Support your statements with appropriate examples and scholarly references. Write your initial response in approximately 300?350 words. Apply APA standards to citation of sources.

19.1: Protists The World of Protists What is a Protist? Kingdom Protista contains the most diverse group of organisms of all kingdoms Most are unicellular (diatoms), but some are multicellular (giant kelp). Some are heterotrophs, some are autotrophs and others are both. The characteristic that all protists share is that they are eukaryotes Protists are divided into animal-like protists, funguslike protists and plantlike protists. Protozoa: animal-like protist, all are unicellular Algae: plant-like protists, do not have roots, stems and leaves Unicellular algae produce most of the world?s oxygen and are the basis for aquatic food chains Fungus-like protists are able to move at some point in their life and do not have chitin in their cell walls What is a protozoan?

Protist Notes Protists Protists belong to the Kingdom Protista, which includes mostly unicellular organisms that do not fit into the other kingdoms. Characteristics of Protists mostly unicellular, some are multicellular (algae) can be heterotrophic or autotrophic most live in water (though some live in moist soil or even the human body) ALL are eukaryotic (have a nucleus) A protist is any organism that is not a plant, animal or fungus Protista?= the very first Classification of Protists how they obtain nutrition how they move Animallike Protists - also called protozoa (means "first animal") - heterotrophs Plantlike Protists - also called algae - autotrophs Funguslike Protists - heterotrophs, decomposers, external digestion .Animallike Protists: Protozoans

Mendel's Genetics ? Hybridized domesticated horses For thousands of years farmers and herders have been selectively breeding their plants and animals to produce more useful?hybrids?. ? It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown.? Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. ? ? Gregor Mendel???? 1822-1884???
