were warm-blooded‚ 4 limbed primates that lived over 7 million years ago. However‚ what really established the basis of humans was the ability of bipedalism walking upright on 2 legs‚ having opposable thumbs to manipulate objects‚ and a voice box larynx that was much lower in the neck for communicating. Walking on two legs gave the perks of using less energy while being able to carry items typically food over large distances. Humans evolved from the groups of “homo” meaning the same.

There are several hundred PAHs‚ which usually occur as complex mixtures rather than as individual compounds. Benzo (a) pyrene is the most widely studied‚ being one of the most potent‚ hence most of the data in this document refers to B(a)P‚ although it seldom occurs in the environment on its own. For the general public‚ the main route of exposure to PAHs is from inhalation of ambient and indoor air or ingestion of food. Inhalation and skin absorption are the main routes of occupational exposure.

The effects of environmental temperature on respiration rates of mice were observed in this experiment. I hypothesized that when environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable

PRINCIPLES OF A REMOVABLE PARTIAL DENTURE A denture should be designed to obtain a balance between mechanical and biological factors. A. H. Schmidt in 1956 stated the following five principle to be considered during the fabrication of a removable partial denture. They are: . The dentist must have a thorough knowledge of both the mechanical and biologic factors involved in removable partial denture design. He must know about the various forces acting on the denture and soft tissues and their

Organization of the human body Human anatomy and physiology – study of the structure and function of the human body. Anatomy- the scientific discipline that investigates the structure of the human body. Physiology – The scientific discipline that investigates the process of functions of living things. 6 Structural levels 1. Chemical level – atoms combine to form molecules 2. Cell level – Molecule form organelles 3. Tissue level – similar and surrounding material make up tissues
