Bio 6 (Mon. Lab) 5/6/13 The Effects of Pepsin VS. Trypsin in The Digestion of Protein Introduction As food is mechanically and chemically digested through our oral cavity then passes through our pharynx and down our esophagus‚ our food then enters the stomach. The stomach‚ being the main organ for storage‚ also helps with breaking down our food‚ but in order to accomplish that our pancreas helps by excreting an inactive digestive enzyme called pepsinogen. Pepsinogen is the inactive form

and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a freshwater habitat. Each organism differs in taxonomic levels from Genus to Species. We knew that the Hydra reproduces with one of two methods: 1) by “budding” which is an asexual method of reproduction

1. Summarise the main development of a child from the age range 0-2 years‚ 3-5 years and 5-8 years. Development refers to the process of learning new skills and abilities‚ and acquiring emotional maturity. All development changes are the result of both genetic and environmental factors. Genetic factors and diet are in the main responsible for growth‚ whereas environmental factors such as quality of the diet and disease are responsible for the emotional growth. ‘Child development’ is the term

Bio Lab Report In part II of the Organic Compounds in Foods lab‚ we to examining whether or not the starch in the saltine cracker can chemically break down in sugar with the presence of salivary amylase‚ which is an enzyme found in your mouth which assists in digestion. My group and I were instructed to obtain a saltine cracker from our teacher and chew on it for approximately 2 minutes. After concluding the chewing‚ we then grabbed a beaker and spit our slimy and chewed cracker into it. Subsequently

If so‚ how? PCO2 level fluctuate from 19.7 to 40. 8. If you observed an acid/base imbalance during this run‚ how would you expect to renal system to compensate for this condition? The renal system will respond by excreting more HCO3- from the body in urine causing a decrease in plasma pH. 9. How did

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Competency Goal 8: Understanding and application of the principles of screening and assessment. I demonstrate competence in the understanding and application of the principles of screening and assessment because I utilize assessment instruments‚ systematic observations‚ developmental profiles‚ and input from other professionals (in the form of IEP/IFSP) and the child’s parents to individualize the curriculum and environment for each of the children in my care.

From the age of 0 to 3 Physical: A new born baby comes with some basic physical survival skills like sucking‚ grabbing and latching onto a breast. By the age of 1 they can roll‚ crawl and sit on their own accord. During the second year‚ most babies become toddlers and begin to take their first steps‚ their muscles have grown stronger now‚ as they progress through the 2nd year they will become more curious of the world around and want to touch and grab anything and everything they can see‚ they will
