We Will follow the development of a fertilized egg from a zygote to a baby. It’s fascinating to see how a single cell develops and grows into a complete baby. check your vocabulary through these introductory questions and follow the power point presentation to check your understanding of the process of development Embryonic Development How Does A ZygoteContinue reading “Embryonic Development”
Sexual reproduction: Involves two parents. Results in offspring that are different from either parent. The genetic variation is due to recombination of chromosomes. This process involves the fusion of two gametes nuclei (egg& sperm). Fusion of the sex cell nuclei occurs during fertilization forming the zygote. Check the details
Facts about meiosis. Meiosis involves two cell division. It produces cells that are different from the parent cell. Each cell has .one-half the number of chromosomes as the parent cell. Meiosis takes place during sexual reproduction, producing sex cells ( eggs & sperms ). It takes place in the sex organs (ovaries & testes) LetContinue reading “Meiotic cell division Meiosis”
Enzymes reduce the activation energy needed for chemical reaction to occur. Enzymes are involved in all metabolic reaction that sustain life. Examples of these reaction are, digestion, synthesis, respiration,and photosynthesis. Review the power point presentation to see how enzymes work.
The processes that help all living things obtain the energy they need are photosynthesis and respiration. photosynthesis capture the sun light and use it to combine the inorganic raw materials (carbon dioxide and water) to form ( the organic compound) glucose and oxygen.the energy that is stored in the chemical bonds of glucose isContinue reading “Topic:The Biochemical Processes That Maintain Homeostssis”
HI ALL, WE ARE GOING TO STUDY TOGETHER THE FEEDBACK MECHANISM, THE PROCESS THAT ALL LIVING THINGS USE TO KEEP A STABLE INTERNAL STATE. WITHOUT THIS PROCESS WE MIGHT GET SICK OR EVEN DIE. YOU WILL BE ABLE TO EXPLORE THIS PROCESS BY FOLLOWING the POWER POINT. Topic: feedback mechanism (1)
Now take another look at homeostasis.Really have fun and enjoy dicussing it with the whole class.
The Immune System Do you know the connection between the immune system and the Coronavirus pandemic? Of course it’s the immune system. Help us fight this contagious viralinfection.You will be able to find out how the immune system protects you from getting sick. The immune system , consists of three lines of defense .
