32.2.2 Segmentation allowed for redundant systems and improved locomotion Hox genes cause segmentation development 2 advantage of Hox genes Highly segmented animals‚ usually have nearly complete set of organs in theirs each segment of body. This result to less damage in their body‚ since other segment duplicate the damage segment functions Locomotion is more efficient‚ since partitions isolate the segment can contract and expand autonomously. 32.3.

Ethics notes Chapters 1 E& 2 Morality is over self intrest and even the law. It is an obligation to do or not do certain things. Philosophy- literally means love of wisdom. From the greek word philia meaning love or friendship and sophia means wisdom. Epistemology- the study of knowledge‚ metaphysics the study of nature of reality‚ and ethics the study of morality. Aesthetics- the study of values in art and beauty and logic the study of argument and the principles of correct reasoning. Ethics-

new symbol we introduce is that of the node‚ shown in Figure 4.1 below. It is simply a point where the current divides or joins. We are now ready to analyze circuits. To analyze a circuit we do two things: 1. find the current in each component‚ and 2. find the potential difference across each component. The rules of circuit analysis are called Kirchhoff’s rules. The Loop Rule This rule asserts that the net change in electric potential around any closed loop in a circuit is zero. This is a statement

occurs in the membranes of chloroplasts or thylakoid discs. Cellular respiration takes place in the membranes of mitochondria. In photosynthesis‚ water breaks down to supply 2 electrons and 2 Hydrogen ions and release ½ O at the beginning of the chain. In cellular respiration‚ 2 electrons at the end of the chain combine with 2 Hydrogen ions and ½ O to produce water. This is the complete opposite. NADPH + H is produced at the end of the chain in photosynthesis. In respiration‚ it is fed into the beginning
