CHAPTER 4 Objectives: 1. Define consciousness.--------- 2. Appreciate the role of the circadian rhythm. 3. Describe the stages (5) of sleep including the sequence of the stages. The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves

CHAPTER I: INTRODUCTION There are many dangerous chemical in our surroundings; most o them can be located inside our own homes‚ almost every household would contain cleaning liquids like liquid detergent‚ mildew removers‚ insecticides and many other harmful chemicals; that is the reason why we decided to focus this investigatory project on creating an eco- friendly cleaning solution. The problem of the modern world is that we have created far too much hazardous chemical since it does the daily

EXERCISE 5 PHYTOGRAPHY: THE FRUIT Name: JOHN REY CORPUZ Score: Date:APRIL 2‚ 2013 Section: I. INTRODUCTION The fruit is a matured ovary containing one or more seeds. It is composed of the exocarp‚ mesocarp and the endocarp. Many floral parts aside from the ovary are persistent and therefore could still be seen in mature fruits. Some examples are the receptacles (apple‚ sepals (eggplant)‚ style (corn) and many more. There are several variations of the

percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the air. At the same time‚ the soil provides water
