Cells‚ Tissues and Organs of the Digestive System Living organisms all have various functioning systems within the body that enable life processes to be carried out. Each system uses different organs that coordinate with each other to carry out their functions‚ and these systems‚ organs and functions are shown below: Functioning System Related Organs Function Circulatory Heart‚ Arteries‚ Veins Transports blood through the body Digestive Mouth‚ Tongue‚ Pharynx‚ Esophagus‚ Liver‚ Stomach

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

BIOB11- Lecture 1 Part 1 First of all‚ just a quick review: there is quite a bit of difference between the prokaryotic and eukaryotic cells. They have different internal structures. Eukaryotic cells have internal membrane structures like nucleus‚ ER‚ Golgi; whereas they do not exist in the prokaryotic cells. When you look at the genetic material‚ DNA‚ you can see that it’s just present in the cytoplasm of the prokaryotic cell while in the eukaryotic cells it is present in the nucleus. An overview

An ecosystem is a biological environment consisting of all the organisms living in a particular area‚ as well as all the nonliving or abiotic‚ physical components of the environment with which the organisms interact‚ such as air‚ soil‚ water and sunlight. In a typical ecosystem‚ plants and other photosynthetic organisms are the producers that provide the food. (Leibold) Ecosystems can be permanent or temporary and they usually form a number of food webs. Examples of ecosystem include: Marine Ecosystems:

Bio Practical Study Notes Some good questions to ask: | | first-hand information and data | secondary information and data | reliability | Have I tested with repetition? | How consistent is the information with information from other reputable sources? | validity | Does my procedure experiment actually test the hypothesis that I want it to? What variables have I identified and controlled? | How was the information gathered? Do the findings relate to the hypothesis or problem? | Control:
