which the child is involved in. The third system of Bronfenbrenner ’s theory on child development is the exosystem‚ which includes other places or people that indirectly influences a child ’s development. One of the most common examples of an exoskeleton is the workplace of the child ’s parents. Although the child will most likely not interact within the parent ’s workplace‚ there are many factors that can affect child

The kermes dye was considered to be native to the old world‚ “Used by the Aztecs for dyeing and painting” (Douma‚ 2008)‚ and the Incas‚ who loved their reds. Throughout this time‚ various native american groups throughout Mesoamerica and South America used as dyestuff. It wasn’t until the 16th Century‚ that the Spanish conquest pushed the kermes dye into the hands of the Europeans. In fact‚ “When Spanish explorers discovered [the dye] and Conquistadors invaded Central and South America in the late

Animal Kingdom The animal kingdom is a taxonomic kingdom composed of multicellular‚ eukaryotic organisms. Mostly‚ their body structures become fixed as they develop‚ yet still some organisms in this kingdom have the ability to undergo metamorphosis. The majority of these organisms are motile‚ which means they can move on their own and with spontaneity. All animals are heterotrophic‚ which implies that they depend on other organisms for food. Animals live in places that provide their necessities

Succession‚ the process of a community changing over time‚ can be broken down into sub groups such as ecological‚ primary‚ pond‚ and secondary. Ecological succession being the most basic. In the Succession Lab‚ we observed a community in a ecosystem. As we recorded the data each class‚ we observed that succession takes place with rapid speed for in each observation‚ a new specimen is identified. A niche is how the organisms live‚ what their role in the community is. For example‚ an ecological

The aim of this investigation was to determine which component wavelength of light functioned best in a brine shrimp’s phototaxic and photokinetic responses. It was hypothesised that the brine shrimp would display a heightened positive phototaxic response‚ and that a more pronounced photokinetic response (increased velocity) would be observed when the samples were exposed to green light. Artemia salina (common name: Brine Shrimp)‚ are from the order Anostraca of the class Crustacea. Adult brine

ROBOTIC’s The dictionary meaning of robot is a mechanical man or a more than humanly efficient automation. It is an automatic apparatus or device that performs functions ascribed to human beings or operates with what appears to be almost human intelligence. But this defamation does not give a human shape to the robot. The robot does the work of a human being. The Robot Institute of America has given a very interesting definition on an Industrial robot. Industrial robots are usually used at industries

How are organisms adapted for efficient gas exchange? [25 marks] Many organisms have different features which enable them to survive and carry out gas exchange effectively. Single-celled organisms‚ such as bacteria and protozoa‚ are in constant contact with their external environment. For them‚ gas exchange occurs by diffusion across their membranes. Even in simple multicellular organisms‚ such as green algae‚ their cells may be close to the environment‚ and gas exchange can occur easily. In

is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil‚ under rocks‚ and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows it sheds its old exoskeleton 4 to 5 times. A pillbug consists of three basic body parts‚ the head‚ thorax‚ and the abdomen. Pillbugs eat decaying plants and animals as well as some living plants. The purpose of this experiment was to learn how to demonstrate the scientific
