While ____ hormones can travel freely in the blood,_____ hormones require a carrier protein because they are not soluble in the
Mandarinka [93]

Answer:

While <u>water soluble</u> hormones can travel freely in the blood, <u>lipid soluble </u>hormones require a carrier protein because they are not soluble in the aqueous plasma

Explanation:

The water-soluble hormones such as insulin are dissolved in the blood and are carried along with the blood to their target cells.  

However, lipid-soluble hormones such as steroid hormones (cortisol) and thyroxine are hydrophobic in nature. These hormones are not dissolved in water-based blood plasma. So, these lipid-soluble hormones are carried through the carrier proteins.

if the stimuli are delivered to the contracting muscles more frequently and ther is no time for relaxqtion
Mamont248 [21]

If the stimulus frequency is so high that the relaxation phase disappears completely, contractions become continuous in a process called complete tetanus.

What is tetanic contraction?

  • When the motor neuron that innervates a skeletal muscle generates action potentials at an extremely rapid rate, a persistent muscular contraction known as a tetanic contraction is induced.
  • A motor unit has experienced its motor neuron's maximum stimulation during this state, which lasts for a while. This happens when several impulses with a high enough frequency excite the motor unit of a muscle.
  • Every trigger results in a twitch. A slow enough stimulus delivery will cause the muscular tension to release between each succeeding twitch. High frequency stimulation will cause the twitches to overlap, which will cause tetanic contraction.
