Which human body systems are involved in thermoregulation
ValentinkaMS [17]

Answer: The nervous system of human body is responsible for thermoregulation.

Explanation:

Thermoregulation is the process whereby an organism maintain its internal temperature despite changes in External temperature. The nervous system of human body is responsible for thermo regulation. The nervous system consist of nerves cells and fibres which send nerves impulses to the body parts. It comprises of central nervous system and peripheral nervous system. The centsl nervous system consist of brain and spinal cord while the peripheral nervous system consist of nerves. A part of the brain (central nervous system)called hypothalamus controls thermo regulation. When it senses a change in internal temperature of the body, its send signals to the organs, muscles, glands and nervous system , they respond differently so as to restore the body temperature to its normal one.

An examiner who discovers unequal movement or uneven gluteal skinfolds during the Ortolani maneuver does what?
expeople1 [14]

Answer:

B. alerts the physician that the infant has a dislocated hip.

Explanation:

An examiner who discovers unequal movement or uneven gluteal skinfolds during the Ortolani maneuver would alert the physician that the infant has a dislocated hip. This can be said because the Ortolani maneuver is a technique that is used in order to check hip integrity, and if unequal movement is detected during this technique it suggests that the hip is dislocated.

What charge does the oxygen atom have in a molecule of water
Afina-wow [57]
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

1. List and explain the difference between the minimum voltage and maximum voltage achieve in a nerve impulse
algol [13]
The normal membrane potential inside the axon of nerve cells is –70mV, and since this potential can change in nerve cells it is called the resting potential. When a stimulus is applied a brief reversal of the membrane potential, lasting about a millisecond, occurs. This brief reversal is called the action potential 
<span>A stimulus can cause the membrane potential to change a little. The voltage-gated ion channels can detect this change, and when the potential reaches –30mV the sodium channels open for 0.5ms. The causes sodium ions to rush in, making the inside of the cell more positive. This phase is referred to as a depolarisation since the normal voltage polarity (negative inside) is reversed (becomes positive inside). </span>

<span>Repolarisation. At a certain point, the depolarisation of the membrane causes the sodium channels to close. As a result the potassium channels open for 0.5ms, causing potassium ions to rush out, making the inside more negative again. Since this restores the original polarity, it is called repolarisation. As the polarity becomes restored, there is a slight ‘overshoot’ in the movement of potassium ions (called hyperpolarisation). The resting membrane potential is restored by the Na+K+ATPase pump.</span>
