What happens to the force of gravity between two masses if they are moved farther apart?
denis23 [38]

Answer:It decreases.

Explanation:Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases. Hope it helps! ^w^

what loop prepares the body for change. This is in contrast to a feedback loop that a. brings a parameter back into the set rang
11Alexandr11 [23.1K]

Answer:

The correct answer is - negative feedback loop.

Explanation:

A negative feedback loop takes place in the biology when the end product of a particular reaction leads to decrease in the reaction. A negative feedback loop makes system to bring the homeostasis.

Negative feedback loops takes place inside the body of an individual to decrease the function of a particular reaction, it prepared the body for the change that occur in the atmosphere such as pH, temperature and other.

Thus, the correct answer is - negative feedback loop.

How does nerve impulses travel from one neuron to another?
olga2289 [7]

Answer:

(d) Electrical-->Chemical-->Electrical

Explanation:

A nerve impulse is the transmission of an electrical change along the neuron's membrane from the point at which it is stimulated (synapse). The normal direction of impulse in the body is from the cell body to the axon. This nerve impulse, or action potential, is a sudden and rapid change in the transmembrane potential difference.

Normally, the membrane of the neuron is polarized at rest, which means that the ionic constitution of the medium internal to the membrane is different from the external medium, which generates different electrical charges in one medium and the other, so this difference, ie , the potential during rest is negative (-70 mV). The action potential thus consists of a rapid reduction of membrane negativity to 0mV and inversion of this potential to about + 30mV, followed by a rapid return to values slightly more negative than the resting potential of -70mV.

Nervous impulse or action potential, therefore, is a phenomenon of an electrochemical nature and occurs due to changes in the permeability of the neuron membrane. These permeability modifications allow ions to pass across the membrane. Since ions are electrically charged particles, changes also occur in the electric field generated by these charges.

Thus, we can say that the correct answer to this question is: Electrical -> Chemistry -> Electrical
