A marine biologist and her team capture 56 sea turtles and mark them before releasing them. The following year, they capture 45 sea turtles at the same location. Of the 45 sea turtles, only 20 have the mark from the prior year. What is the estimated population of sea turtles for that location? A.25 sea turtles
B.126 sea turtles
C.160 sea turtles
D.240 sea turtles

No it doesnt because it can be any number.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Change of odor change of color for example, silver to reddish-brown when iron rusts. change in temperature or energy, such as the production (exothermic) or loss (endothermic) of heat.hopefully this ! : )
