Answer:
OMG I READ THAT BOOK THAT'S SO FUNNY DDFHBJK
Explanation:
I definitely need to work on forgiving. Sometimes I lie to myself and convince myself I'm a forgiving person, but at night when I think about all the things people have done to me or even seek revenge, I realize I'm really not. I spend too much time thinking about other people and what they've done when I really should let it go. My new strategy is to think maybe they are going through something and therefore need attention or like something.
Answer:
You'll have to find that A- can only receive with A- and O-, O- can only receive with O-, B- can only receive with B- and O-, and then AB- can only receive from AB-, B-, A-, and O-.
Explanation:
I believe if you have every blood type sample individually under the microscope, you can take another sample of everyone's blood type and start with O- under the microscope and see how it reacts. If it breaks up and looks separated, it is not the correct receiving blood type, but if is flush and all the same dark red color that isn't broken up at all, then that blood type can be received by the person. The O- blood type can ONLY receive O-, so you will have your first match (two matches because each blood group is represented by two people). You will have to continue you this process and go through each blood sample to see if they match. You'll have to find that A- can only receive with A- and O-, O- can only receive with O-, B- can only receive with B- and O-, and then AB- can only receive from AB-, B-, A-, and O-.
Answer:
The umbilical vein is connected with the vena cava through ductus venosus (structure B).
The Pulmonary artery is connected with the aorta through the ductus arteriosus (structure D)
Explanation:
The diagram depicts the mother and fetal circulation. Oxygenated blood enters the fetus through the umbilical vein. While some of this flow is diverted towards the developing liver vessels, the majority flows directly into the inferior vena cava, bypassing the liver by means of a transient fetal vessel called the ductus venosus.
In the normal postnatal circulation all of the blood coming from the pulmonary artery flows towards the lungs. In the fetus, however, a significant fraction of this blood is shunted into the Aorta instead through another transient fetal vessel known as the ductus arteriosus.
