Explain why even though we might call the exercise a “push-up”, skeletal muscle are still pulling? In your answer, be sure to me
Anarel [89]

Answer:

Agonist muscles and antagonist muscles refer to muscles that cause or inhibit a movement.

Explanation:

Agonist muscles cause a movement to occur through their own activation.[4] For example, the triceps brachii contracts, producing a shortening contraction, during the up phase of a push-up (elbow extension). During the down phase of a push-up, the same triceps brachii actively controls elbow flexion while producing a lengthening contraction. It is still the agonist, because while resisting gravity during relaxing, the triceps brachii continues to be the prime mover, or controller, of the joint action. Agonists are also interchangeably referred to as "prime movers," since they are the muscles considered primarily responsible for generating or controlling a specific movement.

rosijanka [135]
Normally, when we watch or hear any public announcements related to someone, or someone else's loved one's death, we feel saddened about it. In Laura's case as she watched an announcement about the death of a young boy's mom due to cancer, her unconditioned response would be to feel sadness regarding the death of the mother.

Errors for the setup of ammonia gas​
givi [52]

The Errors for the setup or preparation of ammonia gas includes:

  • inadequate temperature use
  • absence of a catalyst
  • inadequate pressure during preparation of the ammonia gas.

Ammonia gas is the hydride of nitrogen. In nature, this gas is produced when nitrogenous matter decays in the absence of air.

In the industrial preparation of ammonia gas, it is manufactured from nitrogen and hydrogen by the Haber process.

Since the direct combination between nitrogen and hydrogen is reversible, special conditions of reaction are necessary for the optimum yield of ammonia. These include:

  • Catalyst: The presence of finely divided iron as a catalyst is necessary for the optimum yield of ammonia gas.
  • Temperature:  the Haber process requires the temperature of about 450°C for the optimum yield of ammonia gas
  • Pressure: A pressure of about 200 atmospheres is required.
