Answer:
Option E.
In order for oxygen in the inspired air to reach hemoglobin, it must diffuse across all of the following structures, except: one or two smooth muscle cells.
Explanation:
- In the process of oxygen reaching hemoglobin it gets diffused across layer of surfactant, an endothelial cell, type I pneumocyte, and the plasma membrane of the erythrocyte.
- The molecule that is responsible for the carrying of oxygen into the blood cells is protein hemoglobin.
- The normal adult human's blood is the mixture of six different species of hemoglobin molecules. These all molecules consist of same function as well as structure.
I would say all of the above
Is that an option?
35 parts per thousand
Sea water. Seawater is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.
The fetus can be screened for abnormalities using karyotyping and biochemical analysis using amniocentesis and chorionic villus sample.
<h3>What data can we glean from CVS and amniocentesis?</h3>
In at-risk fetuses, these tests can detect genetic illnesses such cystic fibrosis, Tay-Sachs disease, and sickle cell disease. The main benefit of CVS over amniocentesis is that it is done considerably earlier in pregnancy—at 10 to 13 weeks as opposed to 15 to 20 weeks—thus saving more time for the mother.
<h3>What can a couple learn about their growing fetus from amniocentesis and chorionic villus sampling?</h3>
Amniocentesis and chorionic villus sampling (CVS) are prenatal diagnostic techniques used to identify certain fetal genetic disorders. The likelihood of miscarriage rises with both procedures.
