Unit 2. Chapters 9-16. Cell Processes 1. Cellular Respiration‚ Photosynthesis‚ Cell Cycle‚ Mitosis‚ Meiosis‚ & Genetics. Note A: All work must be hand-written‚ including charts & diagrams. Note B: each answer requires more than one sentence & use diagrams whenever possible; failure to use diagrams will result in less points. Chapter 9 Outline 1) Principles of Energy Conservation a) Cellular respiration and fermentation are catabolic(energy – yielding) pathways b) Cells must recycle the ATP

Gregor Mendel believed that genes followed “natural laws” and could be expressed in simple mathematical terms (Brooker 19). He was mostly intrigued by how genes varied as they pass from generation to generation (Brooker 18). Mendel decided to test his mathematical hypothesis using pea plants since they came “in several varieties‚ which varied in height and in the appearance of their flowers‚ seeds‚ and pods‚” (Brooker 19). He also decided to use self-fertilization and cross-fertilization to see which

during sexual reproduction is random fertilization. It is when any sperm and egg meet randomly during fertilization. Recombination also happens during sperm and egg production or meiois. Mutations also occur during meiosis. Meiosis is what makes the gametes or the sperm and egg.

Structures: the female reproductive system structure has the ovaries‚ fallopian tubes‚ and uterus. Also include the vagina‚ vulva‚ mammary glands and breasts. These organs produce sex hormones. They also are part of a production and transportation of gametes. Function Is that they produce female eggs cell as needed and they are called ova or oocytes. They system of it is that they transport the ova to where they get fertilization. When the egg is being fertilized is by sperm which is normally by the

The body systems The Musculoskeletal system consists of the bones‚ muscles‚ ligaments and tendons. It provides structural support for the entire body. The musculoskeletal system allows and controls movement. The Cardiovascular system is responsible for transporting and removing gaseous waste from the body. The cardiovascular system is made up of your heart‚ blood vessels (arteries‚ veins‚ capillaries) and blood. The four major functions of the cardiovascular system are: To transport nutrients‚

“Hitler Clone’s and playing G-d?” “Hitler Cloning” and “scientists playing God” are statements used to describe human cloning. When it comes down to the truth of the matter‚ human cloning is a scientific breakthrough that has a higher chance of helping society than hurting it. There are many people who are skeptical‚ believing that a world full of genetically reproduced miniature Hitler’s will be created through human cloning. They imagine a second Holocaust starting as the cloned Nazi

The respiratory system is composed of the nasal cavity‚ nostril‚ oral cavity‚ pharynx‚ larynx‚ trachea‚ carina of trachea‚ right main bronchus‚ right lung‚ left main bronchus‚ left lung‚ and diaphragm. These major organs collectively work together to give the body oxygen and eliminate carbon dioxide as we breathe. In order for the respiratory system to be fully capable of function‚ four procedures (pulmonary ventilation‚ external respiration‚ transport of respiratory gases‚ internal respiration)
