Which statement best describes how reproduction leads to natural selection in a population?
organisms do not produce many offspring, so all of them can survive and pass on their traits.
organisms overproduce offspring; consequently, all of them are likely to survive and pass on traits.
organisms overproduce offspring, so only some survive and pass on their traits.
organisms do not overproduce offspring; therefore, those that are produced will develop the best traits.
the kinetic energy is 8100 j.
mass is 50.0kg and velocity is 18 m/s, the kinetic energy is:
as we know the formula of kinetic energy which is k.e = ½ ( mv ^ 2 ),
mass = m = 50.0kg
velocity = v = 18 m / s,
by putting values in the formula,
k.e = ½ ( mv ^ 2 ),
k.e = ½ ( 50kg ) . ( 18 m / s ) ^ 2
k.e = ½ ( 50kg ) . ( 324 ),
=> k.e = 1/2 ( 16200 ),
=> k.e = 16200 / 2,
=> k.e = 8100j.
hence, the kinetic energy ( k.e ) is 8100 joule ( j ).
answer: option (b) is the correct answer.
when model b shows three dimensional shape of the molecule then it becomes easier to visualize the exact shape or geometry of the molecule as we get to know how atoms are bonded together.
therefore, with the of this it would be easy to know the hybridization of molecule. basically, we will get to know the type of molecule represented by model b.
thus, we can conclude that the statement model b shows the three-dimensional shape of the molecule, but model a does not represents model b better than model a.
