Answer:
The upward buoyancy force on an object acts through the overall center of buoyancy, being the centroid of the displaced volume of fluid. The weight force on the object acts through its center of gravity.
Still there ain’t no picture
The snake and rat both share the same ancestor population that had a quadrate bone, which was inherited from an ancestor population.
<h3>What is a homo-logous structure?</h3>
A homo-logous structure is a trait that may or not have the same function but has a common evolutionary origin.
A homo-logous structure can be used to trace the evolutionary relationships between species.
Conversely, an analogous structure has the same function but it does not reflect an evolutionary origin.

Nuclear Reactor is made to use the energy which is released due to nuclear fission reaction.
These chain reactions are very fast and they are used with some components which can control these reactions otherwise these reaction will start with high rate and could not be controlled after that.
In order to control these reactions we need to control the high energy particles which can stimulate these reactions
These are neutrons which act as catalyst of these nuclear reactions and these reactions can be control by controlling the numbers of neutrons
These neutrons can be absorbed by some mechanism and the rods which are used to absorb these high energy neutrons are known as control rods.
So correct answer must be control rods
Answer:0.8 meter
Explanation:
Frequency=426.7hz
Velocity=346m/s
Length =velocity ➗ frequency
Length=346 ➗ 426.7
Length =0.8
