Answer: A.) sensor
Explanation:
Homeostasis is the ability of the organism's inner body to regulate the internal environment in stable state with respect to the changes occurring in the external environment. It is usually done by the feedback controls.
The maintenance of homeostasis within the body is essential. The following are the factors which controls the homeostasis. These includes:
1. Stimulus: It generate a response. It is an external factor which brings change in the internal body of the organism.
2. Receptor/ sensor: It detects the external stimulus and responds to the change.
3. Control center: The information from the receptor travels along the afferent pathway towards the control center. The function of the control center is to determine the response and controls the action.
4. Effector: The information from the control center travels down the efferent pathway to the effector. The function of the effector is to balance the stimulus to regulate and maintain homeostasis.
Answer:
3. increases with an increase in temperature.
Explanation:
The air more water vapor at higher temperatures because at higher temperatures the air expands and the inter-molecular space increases so the room for water molecules increases.
Warm air keeps the water molecules warm and prevents them from condensing.
The air can hold the moisture only upto its saturation quantity after which the precipitation occurs in the form of rain, snow, hail, sleet etc.
Conductivity is required for the electric current to flow.
Answer:
Fa = -Ff provided that the angle between Fa and Ff is zero
Explanation:
Since the net force is zero, the sum of adding all external forces onto the cart must be zero.
Assuming there is no other forces acting on the cart and Fa acting in the same plane as Fc (i.e. zero angle between acting forces),
Fa + Ff = 0
Hence
Fa = -Ff
Answer:
The pair of terminals to produce an output voltage of 8V are K and M.
Explanation:
A transformer is an electronic device that can be used to increase or decrease an output voltage. It consists of secondary and primary coils, and operates on the principle of induction.
=
where: is the voltage in the secondary coil, is the voltage in the primary coil, is the number of turns in the secondary coil and is the number of turns in the primary coil.
In the question, let us combine the number of turns in the secondary coil. So that,
= 15 + 5 = 20
=
=
= 8
= 8V
For the output voltage to be equal to 8V, the pair of terminals required are K and M.
