Explanation:
El flujo sanguíneo en el lecho capilar es el 5% del gasto cardíaco y depende estrechamente del resto de los vasos que integran la microcirculación. La estructura de los capilares varía de órgano a órgano, pero típicamente están formados por una capa única de células endoteliales apoyadas sobre una membrana basal.
Answer:
The Oxygen (O2) from Hemoglobin A from the bloodstream is transferred to Hemoglobin F in the placenta due to its higher affinity for Oxygen (O2).
Explanation:
Hemoglobin is a metalloprotein that binds to Oxygen (O2) using its central Iron (Fe) atom which is bound to the heme group.
Hemoglobin A is glycated hemoglobin found in the bloodstream. It functions primarily in the Oxygenated red blood cells. There it carries Oxygen to the various tissues. Due to the coupled monosaccharide (usually glucose), it has less affinity for oxygen and would easily release its bound oxygen to a molecule with higher affinity.
Hemoglobin F found in the placenta is the Hemoglobin found in the placenta during pregnancy and for a few weeks after birth. It has a higher affinity for Oxygen and would readily attract Oxygen from Hemoglobin A due to its lack of bonding with any sugar particularly 2,3-bisphosphoglycerate (2,3-BPG or 2,3-DPG).
This difference allows the fetus to access oxygen optimally from the mother's oxygenated hemoglobin.
Hence the statement is best comleted as such "This difference in affinity for Oxygen (O2) allows Oxygen (O2) from the hemoglobin A in the bloodstream to transfer to the hemoglobin F in the placenta".
Answer:
Central Nervous System
Spinal Cord
Peripheral Nervous System
Explanation:
The Nervous System has two MAIN parts. The Central Nervous System is made up of the brain and spinal cord.
The Peripheral Nervous System is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Hopefully, this answers's your question.
DNA is made of deoxyribose, phosphate, sugar and nitrogen bases so the answer is ribose that is not part of a molecule of DNA :)))
I hope this is helpful
have a nice day
Tree transpiration is the process by which moisture (water) is carried through the tree from the roots to small pores on the underside of leaves.
