Sharkwater response

In the past I had watched something similar to the movie “sharkwater”, it is called “Gordon Ramsay: Shark Bait”.  Gordon Ramsay goes on a similar journey like Rob Stewart did to find out the secret behind the shark hunting industries. Both of these documentaries shocked me but considering human nature’s aptitude for destruction it did not surprise me. Frankly, I believe that this sort of fishing is disgusting and should be banned. I am one of those Chinese- Canadian that don’t feel shark fin soup is part of the culture. I have personally never had shark fin soup and I probably never will.

I can understand why there are complaints filed against the Toronto’s shark fin ban because it takes away a tradition. However, when the said tradition involves the merciless killing of an endangered animal and the destruction of an ecosystem I don’t think that’s acceptable anymore. Another reason why people might complain is because by banning shark fin, you’re removing a very large industry that produces a lot of profit. However I don’t think that’s a valid reason because the profit only benefits the people involved in the industry. Also, the shark fin industry is already delving into the illegal territory so it’s not bad to ban the shark fin soup.  

Cellular Respiration Activity – Clothespins and Muscle Fatigue

Purpose: to explore the relationship between cellular respiration and muscle fatigue

Material: clothespin, timer or clock

Procedure:

1.       Hold a clothespin in the thumb and index finger of you dominant hand.

2.       Count the number of times you can open and close the clothespin in a 20 second period while holding the other fingers of the hand straight out. Make sure to squeeze quickly and completely to get the max number of squeezes for each trial.

3.       Repeat this process for 6 more 20 second periods, recording the result for each trail in a suitable table. Try not to rest you fingers between the trials.

4.       Repeat this procedure for the non-dominant hand.

5.       Prepare a suitable graph.

Experiment:

Trials\hands	Right (dominant)	Left (non-dominant)
1	105	87
2	99	92
3	92	89
4	80	89
5	79	96
6	73	92
7	102	90

Analysis:

1.       What happened to your strength as you progressed through each trial?

My strength decreased as I progressed through each trial. However during the activity I allowed my hand to rest for a bit which allowed me to gain back some strength.

2.       Describe how your hand and finger felt during the need of your trials.

My hands felt stiff and tired.

3.       What factors might cause you to get more squeezes (to have less fatigue)?

Factors are focusing my mind on other things, consuming things that may give me energy and the amount of rest I had previously

4.       Were your results different for the dominant and the non –dominant hand? Explain why they would be different.

Yes, they are different. This is because we tend to use the dominant hand more than the non-dominant hand. As result, the dominant hand is more adjusted to performing labour.

5.       Your muscles would probably recover after 10 minutes of rest to operate at the original squeeze rate. Explain why.

The reason we feel the fatigue is due to the build-up of lactic acid. Thus is we rest 10minute. We allow to lactic acid to be removed.
