34B Frog cardiovascular Physiology: computer simulation 1. What was the baseline heart rate for the frog? Ans: 59-63 bpm 2. Which wave is larger‚ the one for atrial constriction or the one for ventricular contraction? Why Ans: Ventricular. It shows the strength of the ventricle as it pumps blood‚ and it is a thicker muscle to pump stronger as it contracts 3. At what time during the contraction cycle was it possible to induce an extrasystole? Ans: The time during the relaxation part of

SIMILARITIES AND DISSIMILARITIES BETWEEN FROGS AND TOADS. Most people find it very difficult to differentiate between a frog and a toad. They often mix them up. Their physical features are very much alike. The physical distinctions‚ however‚ can easily get blurred because sometimes the features appear mixed or less obvious‚ and certain species even legitimately fall into both categories. Although frogs and toads seem similar in appearance‚ they are very different on the basis of origin

Lesson 36 Assignments Biology Muscles and the Skeleton Provide Action and Support Every movement you make or every step you take is controlled by the systems of muscles and skeleton that moves and supports the body. The human boy is a complex and elegant mechanism influenced my many factors. Both muscles and the skeleton are not only good for movement‚ they also influence crucial functions inside the body and the skeleton provides support in maintaining the body’s shape and it protects internal

The action of ANS-related drugs on smooth muscle Introduction In the following experiment‚ the key objective is to compare the mechanical changes in tonic force by longitudinal smooth muscle after the addition of different concentrations of the drugs noradrenaline and acetylcholine. Peristalsis is the wave of muscle contractions that allow circular muscles to constrict the gut and longitudinal muscles to shorten it in an attempt to move the food bolus towards the rectum. A series of dilutions

1.The atria does not perform any contractions since it is directly linked to the SA node. The SA node is being blocked was causes no signals to be sent to the atria muscle‚ resulting in no contraction of it. On the other hand‚ there will be contraction at 40 times per minute for the atrioventricular because this node has its own pacemaker which will allow it to spontaneously contract by depolarizing without any other signal or stimulus--thus‚ even though the SA node signals are blocked‚ the ventricles

In “The Notorious Jumping Frog of Calaveras County” and “How to tell a story” many different forms of humor are used in the stories. One example of humor is shown when the narrator overly exaggerates his description of Jim Smiley. He says that “ If he even see a straddle-bug start to go anywheres‚ he would bet you how long it would take him to get to‚ and if you took him up he would follow it all the way to Mexico.” The writer is using this to present a comedic tone to the audience to entertain them

Literary Analysis of “The Celebrated Jumping Frog of Calaveras County” Mark Twain‚ a folktale writer‚ presents a man by the name of Simon Wheeler‚ who tells a story about a friend of his and that friends name is Smiley. Smiley really loves to gamble‚ and will always place a bet on anything that has to do with competition. He finds a frog and trains him to jump really high so he can gamble with the frog and earn money‚ but the bet does not turn out that way. The author uses setting in a way that

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

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

It is apparent that Hop-Frog or The Eight Chained Ourang-Outangs is a text that exemplifies the goal of Southern Gothic Literature to create confusion between good and evil. Edgar Allan Poe’s short story depicts Hop-Frog’s intentions to exact revenge upon the king. Hop-Frog treatment at the hand of the king is anything but enjoyable. The king begins by forcibly carrying Hop-Frog and his friend Tripetta from their villages. Within the palace‚ they are both subject to constant abuse from the king and
