Temperature and Respiration in Crickets Planning
I am going to investigate respiration in crickets and how temperature
varies the rate of respiration. The calculation for aerobic
respiration is:
[IMAGE]Oxygen + Glucose Carbon dioxide + water + energy
[IMAGE]6O2 + C6H12O6 6CO2 +6H2O + (J)
I will do the experiment safely by making sure that the water will not
be too hot or too cold, this is a safety precaution for me as well as
the crickets. As we don't want to cause the crickets too much distress
or pain.
It will be a fair test and accurate because I will:
v Use the same crickets
v Same mass of crickets
v Let the crickets return to room temperature
v Reset the measuring device after each experiment
v Do each experiment 3 times to get an average
I predict that the lower the temperature the lower the rate of
respiration.
Equipment list:
v 2 beakers- a lager one that will hold the different temperatures of
water, a smaller one to hold the ink marker.
v Crickets- to test on
v Bung- containing delivery tube and waste (reset) tube
v Ink- to mark distance on the scale
v Delivery tube with scale on- to mark distance
v CO2 remover- to remove the CO2
v Excess tube for reset.
I will measure the amount of oxygen used by the crickets by measuring
how far the ink marker has traveled up the scale, the rate of

Animal metabolism consists of the utilization of nutrients absorbed from the digestive tract and their catabolism as fuel for energy or their conversion into substances of the body. Metabolism is a continuous process because the molecules and even most cells of the body have brief lifetimes and are constantly replaced, while tissue as a whole maintains its characteristic structure. This constant rebuilding process without a net change in the amount of a cell constituent is known as dynamic equilibrium (Grolier1996). In the combustion of food, oxygen is used and carbon dioxide is given off. The rate of oxygen consumption indicates the energy expenditure of an organism, or its metabolic rate (Grolier1996).
The Effect of Temperature on the Rate of Respiration in Yeast There are two types of respiration in yeast: Aerobic: [IMAGE] Anaerobic: Glucose [IMAGE] Carbon dioxide + ethanol + energy Respiration is controlled by enzymes, which are proteins which speed up one or more biological reactions. Within any cell many chemical reactions are going on at any one time. Yeast has many different types of enzymes that speed up respiration. Prediction I predict that as temperature increases, the rate will also increase, until a certain optimum temperature, after which, the rate will decrease until the rate is zero as respiration has stopped completely. Reason
Dab on a cotton ball and rub it. You may also put a cotton ball soaked as a compress for an immediate cooling effect. Do this two times a day in the evening and when in the morning.

water and the slower the reaction will be. If the pot is close to the
Margaret Atwood's “Bluebeard's Egg” is a story centred upon a woman called Sally, describing her relationship with her husband, Ed, and her best friend, Marylynn. The story is told in a third person perspective, a “God-like” figure that takes us through the whole narration, but only revealing the thoughts of one character, Sally. In the story “Bluebeard's Egg”, the main conflict is within the protagonist, Sally; that is, her external self versus her internal self. Sally's external self does not act according to her internal self. In other words, Sally does not express her emotions and thoughts due to the many concerns that she has, both psychological and environmental.

Introduction: Respiration, commonly known as the inhalation, exhaling or breathing, has a little known definition. This is the definition that involves the cellular level of eukaryotic cells. Cellular respiration may best be described by the following equation: C6h1206+602-6CO2+6H20+36ATP. ATP is the energy needed for a cell to function as part of cellular respiration. ATP is needed to power the cell processes.
be to increase the temperature by only 5 C each time instead of 15 C.
Geraldine Brooks the author of People of the Book conveys the story of Sarajevo Haggadah. In the chapter “An Insect’s Wings,” Lola, a young Jewish girl, experiences running away from Nazis and coming back to Sarajevo. In this chapter, it also shares some details of how the famed Sarajevo Haggadah was saved from WWII. This chapter shares the journey of Lola and all the unpleasant events she went through.
Global warming is one of the most serious problems that people all over the world are dealing with. In fact, however, many people may not realize that global warming also affects animals as badly as it does to human. All Americans should help protect animals from global warming because global warming changes animals’ habitats, decreases food supplies of animals, and even shortens animals’ lifespan.
Age is a factor that can influence the temperature as old people tend to have a lower body temperature due to being less active and due to the lack of the fat layer below the skin which makes it hard to indicate the presence of an infection ( Medline plus 2015 ). the body temperature is Also higher in the evening then in the morning (Marieb & Hoehn 2010, cited in Dougherty & Lister 2015). Another factor that can influence the body temperature is food consumption including coffee and alcohol or the amount of exercise done (Marieb & Hoehn 2010, cited in Dougherty & Lister 2015). The body surface that is exposed to the environment like cold or heat for example when having a shower or wearing inappropriate clothing ( Wilson's Temperature Syndrome 2016) .As a non-invasive method temperature measurement can be performed using different sites like oral, axillary and tympanic. The rectal has been demonstrated to be the more accurate one but due to his invasive nature and the fact that not only dignity but also privacy of the patients need to be considered , it is not always the first choice. Therefore, although the ear canal route does not provide the most accurate reading as the procedure might not be performed correctly , the tympanic thermometer tents to be preferred not only by the nurses but also by the patients as it is non-invasive, easy to use, safe (Haugan et al. 2013) and the disposable cover is used for prevention and control of infection( Dougherty & Lister
