Answer:
- The recoil force of a bazooka (reaction) + the accelerating force of a missile
- When walking, the foot pushes down and back (action) + the floor pushes up and forward
- When a rocket is taking off, the combustion of the fuels (an action) creates a direct and opposite reaction which is the thrust of the rocket upwards.
Explanation:
Newton's third law states that for every action (force) in nature there is an equal and opposite reaction. Simply put, forces act in approximately equal and opposite pairs (Action and Reaction).
This law is one of the reasons why the foundation of a building must be built in such as way that is exerting equal and opposite pressure against the building which it is carrying. When the forces are equal, the balance of forces are said to be in equilibrium.

The right answer is inversion.
Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.
In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).
We distinguish :
Paracentric inversions: The centromere in the chromosome is not included in the inversion.
Pericentric inversions: The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>

Explanation: because you can really tell. Correct
Answer:
spinal cord
Explanation:
Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.
Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.
Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.
Hence, the correct option is spinal cord.
