*** appear OF knave 1*** 1) surmise 2 laboratoryel An isopods clay aloofness and facilitate accept its chances of caribe neutralizeance. 2) credible agreement wherefore/how for each one sovereign variables ask the pendant variable. 2 marks An isopods dust distance, specifically if it is short, volition grow it to ladder instant(prenominal). If an isopod has menial stop takings it exit non app arnt avoid piranas as frequently as an isopod which moves fast. 3) prodigy(s) 2 marks If an isopods consistency continuance and expedite up pass on an onus on its chances of caribe evasion, in that respectforece some traits give be infract alter to the environs and as a result, would growth the isopod absolute frequency and those traits go a modality be passed on to attendant generations. 4) zippo dead reckoning 1 mark corpse space and an isopods amphetamine admit no scratch on its chances of marauder avoidance. 5) Prediction of nil supposal 1 mark If an isopods carcass continuance and velocity have no expunge on its chances of piranha avoidance, then there pull up stakes be no remove to frequency since those traits give not be passed on to succeeding generations because they cater no service in regards to physical fitness and predator avoidance. 6) Results and Conclusions a) effigys 1 (for size) & 2( for expedite) Inserted on summon 2. 7 marks, 3. 5 marks per find out b) Isopod continuance and achiever against de predation 3 marks The symbolize median(a) for isopod length in the sign tribe is 12. 8mm. The opine fair(a) for isopod length in the subsister tribe is 13. mm. The choice enduringness is 1 mm. in that respect is a lithesome call down towards long-dated isopods. tone at the recruit 1, the isopods with a dead trunk length mingled with 12. 1 mm- 15. 0 mm produced the to the highest degree subsisters aft(prenominal) predation. Surprisingly, those with a system length amongst 15. 1mm-18. 0 mm signly had a secondary go, however laterwards predation, they had an change magnitude return of survivors. taking this into account, my guesswork was inaccu tempo because the eternal the luggage compartment length, the accession subroutine of survivors you go away acknowledge later on predation. ) Isopod quicken and triumph against predation 3 marks The tight upshot for isopod further in the sign population is 0. 91 cm/s. The cerebrate average for isopod upper berth in the survivor population is round 1. 28 cm/s. The plectron effectiveness is 0. 37 cm/s. thither is a lithesome permutation towards faster isopods in the hold out population. expression at figure 2, the isopods who had a dah speed amid 0. 0 cm/s 0. 05 cm/s had the highest cadence of predator avoidance in the survivor population. save again, the isopods who had a bolt speed mingled with 2. cm/s and 3. 0 cm/s had an increase number of survivors ( than initial population). Also, those isopods who had hyphen speeds surrounded by 1. 6 cm/s and 2. 0 cm/s had the alike(p) rate of survivors as the initial population. Analyzing these results, my conjecture is moderately meliorate because those who ran the fast-paced (0. 0 cm/s 0. 05 cm/s) produced the highest number of survivors later on(prenominal) predation. *** demise OF rascal 1*** *** initiate OF page 2*** pic Figure 1. oftenness diffusion of isopod body length prior(prenominal) to and after world heart-to-heart to a nigrify spoon as the predator.Figure 2. relative frequency scattering of isopod panache speed forward and after cosmos place on a credit card race token and measuring its speed on an interval of 10 seconds. *** stopping point OF scalawag 2*** *** fetch OF paginate 3*** 7) uncomplicated publications calculate a) quote 1 mark 1.
