Answer:
Persian-speaking scholars have been active in furthering knowledge in fields of science and technology, such as astronomy, chemistry, anatomy, biology, botany, cosmology, mathematics, engineering, and architecture. Ancient Sassanid Persia was home to some of the earliest universities and libraries of the ancient world.
Introduction :-)
The <em>amniotic fluid</em> is the protective liquid contained by the <em>amniotic sac</em> of a <em>gravid amniote</em>. This <em>fluid</em> serves as a cushion for the growing <em>fetus</em>, but also serves to facilitate the exchange of nutrients, water, and biochemical products between <em>mother</em> and <em>fetus</em>.
Importance :-)
- <em>It helps to protect the fetus from trauma to the maternal abdomen.</em>
- <em>It cushions the umbilical cord from compression between the fetus and uterus.</em>
- <em>It has antibacterial properties that provide some protection from infection.</em>
- <em>It serves as a reservoir of fluid and nutrients for the fetus.</em>

Formation :-)
<em>Amniotic fluid </em>is present from the formation of the <em>gestational sac.</em> <em>Amniotic fluid </em>is in the <em>amniotic sac.</em> It is generated from <em>maternal plasma</em>, and passes through the <em>fetal membranes</em> by <em>osmotic</em> and <em>hydrostatic forces</em>. When <em>fetal kidneys</em> begin to function around week 16, <em>fetal urine</em> also contributes to the <em>fluid.</em> In earlier times, it was believed that the <em>amniotic fluid</em> was composed entirely of <em>fetal urine</em>.
The <em>fluid</em> is absorbed through the <em>fetal tissue</em> and <em>skin</em>. After <em>22 to 25 week </em>of<em> pregnancy</em>, <em>fraternization</em> of an <em>embryo's skin</em> occurs. When this process completes around the <em>25th week</em>, the<em> fluid</em> is primarily absorbed by the <em>fetal gut</em> for the remainder of <em>gestation</em>.
<em>Contents :-)</em>
At first, <em>amniotic fluid</em> is mainly water with <em>electrolytes</em>, but by about the <em>12-14th week</em> the <em>liquid</em> also contains <em>proteins, carbohydrates, lipids and phospholipids, and urea</em>, all of which <em>aid</em> in the growth of the <em>fetus</em>.
Hope its helpful :-)

Answer: Lymph node
Explanation:
The lymphatic system of the body works by filtering the blood and remove the harmful pathogen that is present in it.
There are several organs in the lymphatic system that works together at different sites in the body and helps body prevent and cure from infection.
Lymph nodes function to remove pathogen and debris from lymph and it is also referred as filters of lymph. The macrophages and dentritic cells kill the harmful pathogen in the blood.
Hence, the correct answer is option A
