Lab 4: Endocrine System Physiology | 1. | | Refer to Activity 1: Determining Baseline Metabolic Rates. How did the baseline metabolic rates of the three rats differ? Answer: | The metabolic rates for the thyroidectomized and hypophysectomized rats were lower than that of the normal rat. | | | 2. | | Why did the metabolic rates differ? Check all that apply: Answers: | The hypophysectomized rat lacked thyroid-stimulating hormone. The thyroidectomized rat lacked thyroxine hormone.

To perform the experiment‚ first the calorimeter was filled with 100 mL of water using a graduated cylinder‚ and the temperature of the water was found and recorded. Next‚ the beaker was filled 3/4 full with water and placed on the stand of the ringstand above a gently burning flame from the Bunsen Burner. Then‚ the mass of the test tube and wax was found and recorded‚ and the tube was placed in the beaker. After the wax in the tube melted‚ the

Biology laboratory work: Osmosis observation Measuring the dependence of net mass gain in potato pieces on concentration of sugar solution By Jonas Kulikauskas Siauliai Didzdvaris Gymnasium Hypothesis: The more sugar in solution‚ the more potato mass will decrease. Aim: To see how potato mass will change at different concentration solution. Research question: How the mass of potato will change at different concentration solutions? Variables: Dependent: solution concentration. Independent:

Abstract: Osmosis is the transport of water across a selectively permeable membrane from a region of a higher water chemical potential to a region of lower water chemical potential. (Tzahi 2006) To demonstrate osmosis lab‚ artificial cells were made with various sucrose concentrations and were placed into beakers of different sucrose solutions. Overall the results showed that the higher percentage of concentration gradient of sucrose‚ the more the artificial cells absorbed. Introduction: The

The changes in the diffusion of Buddhism and Hinduism through 600 CE greatly impacted these religions such as the popularity of the religions in India and where the religions was being diffused; however‚ a few continuities existed such as they both originated in India. Since Hinduism reinforces the caste system and Buddhism believe in equal treatment of all people which opposes the caste system‚ Buddhism started to spread into other areas other than India to offer an alternative to Hinduism for
