Hypothalamus
the cardioregulatory center is located in the medulla oblangata of the brain and can alter the heart rate by way of the autonomic nervous system.

Peripheral resistance is the force against blood flow. In most cases, an increase in peripheral resistance would be caused by an increase in vasoconstriction, which would decrease blood flow. Other factors can influence vasoconstriction, such as circulating angiotensin II levels, cortisol levels, drugs such as cocaine and other adrenergic agonists, blood volume, atherosclerosis, emboli, renal diseases and increased intra-cranial pressure. An increase in blood pressure will also be caused by vasoconstriction and the mentioned factors.

The resistance of the wire is directly proportional to the length and inversely proportional to the area of cross section. Also it depends on the material of the wire with which it is made. So three factors. Length, area of cross section, material.
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
You could increase the length of the wire or decrease its thickness to increase resistance in the electric circuit. Both of these changes will hinder the flow of electrons through the wire, resulting in higher resistance.
The resistance can be changed in following two ways: 1.By change the length of the wire. 2.By changing the area of cross section of the wire.
Yes, air resistance (also known as drag) does have an effect on a projectile's motion. It opposes the projectile's motion, slowing it down and causing it to lose kinetic energy. This can alter the trajectory and distance traveled by the projectile.
Yes, bending the wire can potentially affect its electrical resistance. The resistance of a wire is influenced by its dimensions, material, and temperature. Bending a wire can alter its cross-sectional area, length, or even cause deformations that impact the flow of electrons and increase resistance.
A thermister is a device that changes resistance depending on temperature. A photo resistor changes resistance based on light. Both of these could be used with an amplifying circuit to vary current flow.
Light does not directly affect a thermistor, as its resistance is primarily determined by temperature changes. However, if light generates heat that affects the temperature of the thermistor, then it can indirectly alter its resistance. In general, thermistors are designed to be affected by temperature changes, not light.
