How does a newborn animal know exactly what to do the moment its born

Svetradugi [14.3K]

A baby animal knows what to do after birth just from natural instinct. Human babies do not get taught how to breath or cry, they know to do so because they would die otherwise.

How do neurons communicate? place in order the sequence of events that occurs when a neuron fires?

monitta

Answer;

-Dendrites receive chemical signals.

-When more excitatory than inhibitory signals are received, the cell depolarizes.

-An action potential is set off and travels through the cell and down the axon.

-The action potential excites the terminal buttons to release their chemicals into the synaptic cleft.

Explanation;

-The electrical signal that passes along the axon and subsequently causes the release of chemicals from the terminal buttons

. Chemical signals (excitatory and inhibitory signals.

-Positive sodium pours into the breach, Action potential propagates along the axon, after firing returns to its slightly negative resting state.

-An action potential can be generated if the amount of excitatory input can raise the membrane potential to -55 mV. This then floods the cell with sodium ions and raises the membrane potential. When it reaches a certain point (about +30 mV), the sodium ion channels close and the potassium ion channels open. This drops the membrane potential back down.

<h2>ANSWER:</h2>

$\huge\boxed{Negative Feedback}$

<h2>_____________________________________</h2><h2>TYPES OF MECHANISMS</h2>

There are two types of mechanisms

<h3>Negative Feedback Mechanism:</h3>

This mechanism opposes the change that occurs in the body resulting in the decrease of the CHANGE.

<h3>Positive Feedback Mechanism:</h3>

This mechanism enhances the change that occurs in the body resulting in the increase of the CHANGE.

<h2>_____________________________________</h2><h2>THERMOREGULATION</h2>

Thermoregulation is the control of body temperature

<h3>__________________________________________________</h3><h3>Decrease in temperature </h3>

This picture is the mechanism for the THERMOREGULATION (control of the body temperature). It is the negative feedback, as you can see if the temperature is decreased that means the change occurs, so the process of shivering starts which is the movement of muscles which generates the heat resulting in the increase in temperature.

CHANGE: Less Temperature i.e. body cold.

NEGATIVE FEEDBACK: Increases temperature and brings it back to normal.

<h3>__________________________________________________</h3><h3>Increase in temperature </h3>

When the Temperature of the body increases, that means when the change occurs, The Negative feedback mechanism is triggered resulting in the process of sweating which brings the body temperature down.

CHANGE: More Temperature i.e. Body hot

NEGATIVE FEEDBACK: Decreases the temperature by the process of sweating and brings it back to normal.
