Answer:
Amoebae use pseudopodia (meaning “false feet”) to move. In the case of an amoeba moving, it's cytoplasm flows forward to form a pseudopodium, then it evens back out. In order to eat, it will form two pseudopodia and wrap those around to meet each other, enclosing its food, then the cytoplasm evens out again.

Answer:
Work = 92,704.5 joules
Power= 154.5 watts
Explanation:
Given that:
Time= 10 minutes
treadmill grade = 15% = 0.15
horizontal speed = 90 meters/min
subjects weight = 70 kg
To calculate the total work, we have;
work = force × distance
force = mass × acceleration
= 70 × 9.81
= 686.7N
Also, distance = speed × time × fractional treadmill grade
∴ distance = 90 meters/min × 10 min × 0.15 (treadmill grade)
Total work can therefore be calculated as:
work = force × distance
work = 686.7N × (90 meters/min × 10 min × 0.15 (treadmill grade) )
Work = 92,704.5 N/m
Work = 92,704.5 joules
To calculate the power, we have;
Power = workdone/time
Power = 92,704.5 joules/600 seconds
Power = 154.5 joules/second
Power= 154.5 watts
