Scientific Method - Mealworms Abstract The experiment is designed to determine which substrate‚ A (oat bran) or B (peat moss) will be better nourishment for a mealworm after exposed for 7 days. A total of 30 mealworms were placed in the substrates for a period of 7 days; 15 in substrate A and 15 in substrate B. The data was compiled and analyzed on day 7 to determine the change of mass in each of the mealworms. The experiment proved my hypothesis to be correct; the mealworms would not thrive

with exercise‚ could be accomplished by increasing the volume of each breath‚ the tidal volume‚ increasing the respiratory rate or by some combination of the two. In the subject’s case it was a combination of the two. Tidal volume is more effective at increasing minute ventilation than respiratory rate‚ however‚ if a subject is unfit they will be required to increase their respiratory rate as they cannot breath as deeply as someone with trained lungs.

Introduction The purpose of this experiment was to study the effects of ethanol on the cellular respiration of mealworms. Cellular respiration is the process by which cells harvest the energy stored in food. It is the intake of oxygen and energy in the form of glucose‚ and the cells ability to break it down into carbon dioxide‚ water‚ and energy required for the body to function. More scientifically‚ it is a three-step pathway that produces ATP (adenosine triphosphate.) The three stages of cellular

Results: The mealworms that were in the room temperature water have a higher cellular respiration rate than the mealworms in the cold water. This is because while they are in the cold water‚ the mealworm’s body slows down which decreases the amount of CO2 that is being produced. Unlike the mealworms in room temperature water‚ their cellular respiration was higher because their body temperature remained the same creating CO2 at a faster rate. Since there were two different controlled groups‚ there

Abstract In this experiment‚ the preferences of mealworms towards lighted and dark environments were tested. The main question posed was whether the behavior of the mealworms would be affected by the variable of light‚ and whether they would move towards or away from the light source (taxis). We placed ten mealworms into two adjoining containers and tried to simulate the effects of above ground and underground by exposing the mealworms to minimal amounts of light in one of the containers (underground)

Analysis Growth of Mealworms Abstract The experiment is designed to show which substrate A or B will better nourishment for a mealworm. A mealworm was placed in each substrate for a period of seven days and the change in mass from Day 1 to Day 7 was compared. The data was compiled and statistically analyzed. The experiment failed to reject the null hypotheses that there would be no difference in the two substrates regarding meal worm growth. The conclusion that there was a difference

The respiratory system of birds differs significantly from that found in mammals‚ containing unique anatomical features such as air sacs. The lungs of birds also do not have the capacity to inflate as birds lack a diaphragm and a pleural cavity. Gas

According to the data‚ the population size obtained for Group RG/CL is an outlier in respect to other groups’ population sizes. After two weeks of sampling and counting the population of mealworms‚ a population of 506 mealworms was calculated. A very broad confidence interval was also calculated‚ ranging from 143.58 to 868.42 (Table 1). Although other groups seem to have large confidence intervals‚ they are within a 200-300 limit. The confidence interval calculated for Group RG/CL has about a 700

Mealworms and Caffeine Caffeine is the most commonly used stimulant in the United States. In North America‚ sixty to seventy five percent of caffeine consumption comes from coffee and fifteen percent to thirty percent comes from tea. It can be found in a variety of forms including: coffee‚ tea‚ chocolate‚ soft drinks. Caffeine is a part of a family of drugs known as methylxanthines.To work‚ caffeine disrupts the neurotransmitter adenosine. Caffeine is known to cause physical dependence in humans

Respiratory Disorders Management and Care Our respiratory system is like a battery in our car‚ without it we will not be able to generate the heart and the rest of our body. There is an old proverb that states‚ "Life is in the breath. He who half breathes half lives." If you have allergies‚ asthma‚ or other breathing problems‚ this proverb may sound very familiar. But a greater understanding of your breathing problems‚ along with an accurate medical diagnosis and effective treatment‚ can help
