DIVISION RHODOPHYTA (RED ALGAE) RHODOPYTA (RED ALGAE) Red algae have been the 1st eukaryotes formed by endosymbiosis involving photosynthetic prokaryotes. Red algae are mostly multicellular It exhibit some of the most complex life cycles It posses cellulose walls‚ chlorophyll a‚ some posses chlorophyll d (chloroplast is present but lacks grana) Contains phycoerythrin‚ phycocyanin and allophycocyanin as accessory pigments. flagella is absent in red algae as well as centrioles 5‚000 species(approximate

testable question was “How does exercise affect your breathing and heart rate?” and my hypothesis was “If you exercise then your heart and breathing rates will go up because your body needs more oxygen to be circulated so that your body can keep up.”. My hypothesis was correct‚ as proven by my test. My partner‚ Brian’s heart rate when it was resting was 56 beats per second and his breathing rate was 40 beats per second. We made him do jumping jacks for ten seconds and his heart and breathing rates both

Abstract This investigation was undertaken in order to observe the effects of changing the temperature of the solution that a potato cube is placed in. The temperatures that were tested in this investigation were 0°C‚ 20°C (room temperature)‚ and 70°C. This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again

increased for processed products that keep more of their original characteristics. In industrial terms‚ this requires the development of operations that minimize the adverse effects of processing. The effect of food processing on finished product quality ultimately determines the usefulness and commercial viability of that unit process operation. In the particular case of food drying this indicates that loss of volatiles and flavours‚ changes in colour and texture‚ and a decrease in nutritional value

Cell Fusion Introduction: The fusion of cells is a fundamental biological event that is essential for a variety of developmental and homeostatic processes. The importance of cell-cell fusion during development and disease is displayed in a variety of biological processes including‚ but not limited to‚ fertilization‚ development of tissues‚ the immune response‚ and aspects of tissue regeneration due to stem cells (Chen and Olson‚ 2005). Fertilization‚ which is the fusion of sperm and egg‚

research in secondary sources‚ such as journals‚ magazines‚ or books. We can also use it as the focus of our writing project. In primary data collection‚ we collect the data ourselves by using methods such as interviews and questionnaires. The key point here is that the data we collect is unique to us and our research and‚ until we publish‚ no one else has access to it. There are many methods of collecting primary data and the main methods include: • QUESTIONNAIRES • INTERVIEWS • FOCUS GROUP
