Arden is making a pros and cons list about genetic engineering for a debate at school. which part of her list is incorrect?
pros cons
pro 1: can be used to make medicine con 1: genetically modified organisms can affect the environment around them pro 2: can create organisms that survive in different environments con 2: the edited gene is more likely to mutate and cause disease
pro 1 pro 2 con 1 con 2

The rearrangement of particles in a physical change. hope this

I'd go for the one that says that knees are fulcrums, lower legs are levers and the ankles hold loads.hope it ,happy homework/ study/ exam!

I'm pretty sure the answer is c 

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
