Answer:

Your heart rate will decrease.

Explanation:

By breathing in and holding your breath, you are further activating the PNS  (peripheral nervous system) causing a decreased heart rate which is also known as bradycardia. In addition, holding your breath will start to create a negative suction pressure in your thorax and will commence to inflate the organs.

→ Basically, your heart rate goes up more or your bodies processes are being used and when you exercise your muscles are being used -  this makes your heart rate go up. <em>However, when you hold your breath your heart rate steadily decreases because your lungs aren't be used and your body is trying to reserve the oxygen that you vitally need.</em>

I hope this is helpful!

denis-greek [22]

Answer:

Molecules  carrying amino acids are positioned in the  ribosome’s two docking sites.

Explanation:

A ribosome is a molecular machine that  coordinates protein assembly.

  • A ribosome brings together correctly the  mRNA, which needs to be translated, and  the tRNA, which assists in the translation process, to come together correctly.
  • During translation, tRNA molecules  carrying amino acids are positioned in the  ribosome’s two docking sites.
  • After the translation, the tRNA disassemble and is being reused many times.
