A group of students performed an experiment to test terminal velocity, which is the greatest speed obtained by a falling object.
The students dropped different numbers of coffee filters and measured the resulting terminal velocity.
Which of the following conclusions is supported by the data in the following data table?

Terminal velocity is when the force of gravity is equal to air resistance.
Heavier objects take more time to reach terminal velocity.
Heavier objects fall faster than lighter objects.
The greater the number of filters, the smaller the terminal velocity.
The Correct Answer is C
The data in the table shows that as the number of filters (and therefore the mass) increases, the terminal velocity also increases.
This means that the heavier objects (with more filters) are falling faster than the lighter objects (with fewer filters).
Choice A is not supported by the data in the table.
Terminal velocity is indeed when the force of gravity is equal to air resistance, but this definition does not provide any information about the relationship between mass and terminal velocity.
Choice B is also not supported by the data in the table.
The data does not provide any information about the time it takes for an object to reach terminal velocity.
Choice D is not supported by the data in the table.
The data shows that as the number of filters increases, the terminal velocity also increases.
This means that the greater the number of filters, the greater (not smaller) the terminal velocity.

Correct Answer is D
Explanation
It can self-renew by dividing and develop into the three primary germ cell layers of the early embryo and into extra-embryonic tissues such as the placenta.
A fertilized egg is a totipotent stem cell and as such can develop into any specialized cell found in the organism.
Choice A is not correct because totipotent cells do not fight infectious diseases.
Choice B is not correct because totipotent cells do not aid in the maturation of sex cells.
Choice C is not correct because totipotent cells do not carry electrical impulses.
