Increase because kinetic energy is all about the speed of an object and the more speed the more kinetic energy.

Well first of all, you must realize that it depends on how the jumpers are distributed on the earth's surface. If,say, one billion of them are in the eastern hemisphere and the other billion are in the western one, then the sum of all of their momenta could easily be zero, and have no effect at all on the planet. I'm pretty sure what you must have in mind is to consider the Earth to be a block, with a flat upper surface, and all the people jump in the same direction.
average mass per person = 60 kg.
jump velocity = 7 m/s straight up and away from the block, all in the same direction
one person's worth of momentum = (m) (v) = 420 kg.m/s
sum of two billion of them = 8.4 x 10¹¹ kg-m/s all in the same direction
Earth's "recoil" momentum = 8.4 x 10¹¹ in the opposite direction = (m) (v)
Divide each side by 'm' : v = (momentum) / (mass) =
The Earth's "recoil" velocity is (8.4 x 10¹¹) / (5.98 x 10²⁴) =
1.405 x 10⁻¹³ m/s =
<em> 0.00000000014 millimeter per second
</em>I have no intuitive feeling for this kind of thing, so can't judge whether
the answer is reasonable. But my math and physics felt OK on the
way to the solution, so that's my answer and I'm sticking to it.
Answer: B) As something approaches an octopus, it shoots a cloud of ink.
A stimulus is something which brings physiological change in the internal or external environment of the organism. Sensitivity is the ability of an organism to respond to the external stimulus or stimuli. These changes are detected by the sensory receptors present in the different parts of the organism. A stimulus can be light, chemical, pressure, temperature and other living organism.
As something approaches an octopus, it shoots a cloud of ink is a physiological response of the octopus to an immediate threat. This immediate threat could be another marine predatory organism acting as a stimulus.
