The answer is D
Because it is kinda basic
Wind produces the energy, initial motion and direction of the surface current of the ocean.A<span>n </span>ocean current<span> is a seasonal directed movement of seawater.
</span>Surface ocean<span> currents are primarily </span>affected<span> by </span>wind. The Gulf Stream is example of it. <span>Trade </span>winds<span> push </span>water<span> along the top of the </span>ocean<span> and this results in formation of surface currents.</span>
In fetal circulation, the ductus venosus bypasses the liver and the ductus arteriousus bypasses the lungs. Ductus arteriosus also called ductus botalli is a blood vessel connecting the main pulmonary artery to the proximal ascending aorta. It does allow most of the blood from right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Ductus venosus on the hand allows oxygenated blood from the placenta to bypass the liver.
You can use dimensional analysis to figure this out.
× 
= 3 grams
If done correctly, ml and ml will cancel out, leaving you with grams.
If you don't know dimensional analysis, simply multiply <em>3 ml</em> by <em>1 grams </em>and that should still get you 3 grams.
B . , because I remember this
