Unit 2 Reflection

Image
This unit was about the essential knowledge in chemistry. From learning about atoms to enzymes, we have learned about their functions and structures. One of the main points we touched upon was the big four macromolecules: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates are saccharides, also commonly known as sugar, that are made of rings of carbon, hydrogen, and oxygen. It's used as energy storage for producers and a main source of energy for consumers. Lipids are molecules that have fat, phospholipids, oils, waves and cholesterol. They contain chains of fatty acids, carbon and hydrogen, and are nonpolar. It's also used as energy storage, but also makes up cell membranes and used to make hormones. Protein is large molecules made of amino acids chained together. This can support the body, speed up chemical reactions, help cells communicate, and let things through the cell membrane. One type of protein is enzymes. Enzymes are amino acids chained together, which ...

Poor Piggy: Pig Dissection Lab

Image
In replace of a video, I decided to write about it instead of show it. External Anatomy: Usually, the fetal pig is a light beige/ off pink color. To dissect it, you must tie down the wrists on the plate to have the ventral area exposed for dissection. The wrists of the pig is cut out of the diagram, but just like humans, it would be located near the ends of the arm. The shoulder is spread openly, which can be found after the elbow of the arm. Digits are essentially the fingers and toes of a pig. They are connected to the wrist, at the end of the arm. Those two structures allow the pig to move. The thoracic cavity is everything from the diaphragm and up. We'll talk about what goes into that portion of the pig later. The abdominal cavity should be everything below the thoracic cavity. To determine the sex, you look at the urogenital opening. On males, it should be located near the umbilical cord. For females, the opening is near the anus. Digestive System: In a digestive sys...
