Embryonic Development

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

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

Meiotic cell division Meiosis

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.

Topic:The Biochemical Processes That Maintain Homeostssis

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”
