Biology: Cells, Energy, and Human Body Systems
I. Science Skills
9 Process Skills: Observing – using senses (see, hear, taste, smell, touch) Communicating – give or receive information Measuring – compare something to standard or non-standard units Classifying – use observations to group objects or events according to similarities and differences Interring – using past experiences to draw conclusions and make explanations about events not directly observed Defining Operationally – using past experiences to draw conclusions and make explanations

Understanding Mitosis, Meiosis, and Genetic Variation
Main Stages of Mitosis
Prophase: cell structures break down and chromosomes divide
Metaphase: chromosomes line up at the middle of the cell
Anaphase: sister chromatids separate and move to opposite ends
Telophase: cell division nears completion and normal structures are re-established
Mitosis vs. Meiosis I
Meiosis has two rounds of genetic separation and cellular division, leading to non-identical daughter cells, unlike mitosis.
Meiosis and Genetic Variation
Prophase I allows for genetic diversity through

Nutrition: an exchange of substances
In order to carry out the nutrition function, living organisms need an exchange of substances to take place between their surrounding environment and their cells. This exchange occurs in different ways according to whether the organism is unicellular or multicellular.
1.1. How substances are exchanged
The nutrition function is performed through the joint action of different systems. The systems involved in human nutrition are:
1. The digestive system: This system
