B. A form of energy coupling refers to using the release of energy from exergonic hydrolysis of ATP to initiate other endergonic reactions for cellular metabolism.
The connective tissue layer surrounding bone is called the periosteum. It has an outer fibrous layer and an inner osteogenesic layer.
Ooh this will be good
So blood let’s say starts in the left atrium where it goes down through the mitral valve into the left ventricle. From the left ventricle of the blood is pushed through the aorta and from there through the various branches of the body eventually allowing oxygen rich blood to flow all across the body. Once this blood is picked up by veins as deoxygenated blood it goes back to the heart through the inferior and superior vena cava. From there the deoxygenated blood is sent into the right atrium, through the tricuspid vale into the right ventricle, through the pulmonic valve into the pulmonary artery and into the lungs for re-oxygenation. The re-oxygenated blood (oxygen rich blood) now goes through the pulmonary veins into the left atrium and the cycle beings again.
Remember this, Left side of heart is for oxygenated blood, Right side of heart is for deoxygenated blood.
Artery takes oxygen rich blood away from heart itself
Vein takes oxygen poor blood back into the heart
Exceptions, Pulmonary Artery takes oxygen poor blood away from heart and into lungs
Pulmonary vein takes oxygen rich blood into the left atrium to be pushed to the rest of e body.
The statement that best describes he purpose of examining mammary secretions in mares before parturition is testing for elevated levels of calcium.
<h3>What is the processes of parturition in mares?</h3>
In parturition, a fetus is fully developed, a process called Ferguson reflex occurs to stimulate contractions. The canal is lubricated by a fluid called allanotic fluid and facilitates the discharge of the amnion and the fetus. A virginal distension releases oxytocin and more contractions.
For a mare to be ready for parturition, elevated levels of calcium is tested from the mammary gland to confirm that the mare is healthy and ready for parturition.
