“So for today we’re going to learn about the six different animal kingdoms.” Both of the cubs cock their heads at her in confusion. “Here, let me explain.” she says realizing their confusion. “There are six different kingdoms of beings, we only live in one of those kingdoms known as Animalia or the animal kingdom. The animal kingdom includes birds, mammals, reptiles you name it. The one thing well all share in common though is that we all eat, reproduce, and eventually pass away.” both of the…

Ever since the beginning of time, natural selection has shaped our world. Natural selection, (also known as evolution), is the process of living organisms adapting and changing to survive in their natural environment. Many of the species that we know today have been involved in the process of evolution. Species don’t evolve like a flip of a switch, but are constantly evolving over a long period of time. As Darwin states, “Evolution occurs every 5,000 years”. There are several types of evolution…

yellow crystalline solid with sweet and musty odor. It is soluble in organic and aqueous alkaline solutions and has the ability to sublime. It is biochemically active compound and act as ionophore by shuttling the proton across mitochiondria and chloroplast membrane to dissipate heat instead of producing ATP [ Mechanism of uncoupling in mitochondria: uncouplers as ionophores for cycling cations and protons, PNAS, R J Kessler]. It is used as antiseptic and pesticide and also used for the…

were slightly different, which contributed to different rates of photosynthesis. The experiment suggests that white light frequencies result in higher rates of photosynthesis than green light. This seems to fit with scientific knowledge, because chloroplast appear greens so therefore reflect some green light frequencies. However, the lab results are questionable because the highest rate of photosynthesis occurred under no light. But, light is the source of energy in photosynthesis. So the…

The reason leaves often change colors when the weather gets colder, before dropping off of trees is because leaves are colored by pigments. In autumn, when it starts to get cold, the leaves start to change their pigment making other colors. Heavy wind and rain can cause leaves to fall off of trees before they are already colored. The reason the fall solo is because the chlorophyll in the leaves break down and the green color in the leaves disappears do to the weather changing. Chlorophyll is…

The purpose of this EEI is to create and analyse an experiment that relates to and supports the theory of osmosis in biological cells. Cells are the biological building block for all life; all living organisms have cells also. Cells provide structure, absorb nutrients from food and convert those nutrients into energy so that the cell can carry out specialized functions. There are two main categories with most organisms and their cells; prokaryotes and eukaryotes. The distinctive difference…

Inside those cells are structures called chloroplast, which contains chlorophyll. Chlorophyll is what gives a plant its color. As I was telling you before, the chlorophyll absorbs the sun’s energy, which is used to split water molecules into hydrogen and oxygen. The oxygen is then released from the…

The Cell Membrane is one of the most important parts of the cell. If not for the cell membrane it would be extremely easy for things to invade the cell; this is because on of the cell membranes job is to control what come in and out of the cell (i.e. ions, viruses, etc). Also the cell membrane is what helps hold the cell and all of its organelles Endoplasmic Reticulum (AKA the ER), smooth and rough whats the difference? The smooth ER does not have any ribosomes while the rough ER is covered in…

The energy used to drive the chemical reactions within photosynthesis comes from the sunlight absorbed by the chlorophyll molecules (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). These chlorophyll molecules then transfer the light energy to chloroplasts and that light energy is converted into chemical energy (Merzlyak, Chivkunova, Zhigalova, & Naqvi 2009). The purpose of this experiment was to observe what the absorbance spectrum of Spinacia oleracea extract was and what the absorbance…

All cells are derived from pre-existing cells - through the process of meiosis and mitosis 4. In a multicellular organism, the activity of the entire organism depends on the total activity of its independent cells 3 Significance of technological advances to developments in the cell theory Assess the impact of technology including the development of the microscope on the development of the cell theory The development of cell theory has been heavily impacted by the improvement of technology. The…
