Answer:

The vessels draining Myocardium of the heart join to form <u>Coronary Sinus </u> that ultimately opens into <u><em>THE RIGHT ATRIUM.</em></u>

Explanation:

<u><em>CORONARY CIRCULATION:</em></u>

The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.

<u>Coronary Arteries</u> supply oxygen rich blood to the myocardium and <u>Coronary Veins</u> remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.

A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozy
Fantom [35]

Answer:

Explanation:

A woman with type A blood (whose father was type O) meaning her genotype is AO mates with

Man that has type O blood (OO genotype)

Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.

Cross

A O M N H h

O AO OO M MM MN H HH Hh

O AO OO N MN NN h Hh hh

Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4

Type A with M antigen:

1/2*1/4*3/4 = 3/32

Type A with M and N antigens:

1/2*1/2*3/4 = 3/16

Type A with N antigen:

1/2*1/4*3/4 = 3/32

Type O with M antigen:

1/2*1/4*3/4= 3/32

Type O with M and N antigens:

1/2*1/2*3/4 = 3/16

Type O with N antigen:

1/2*1/4*3/4 = 3/32.

The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).
