The amniotic fluid helps keep the temperature of the prenatal world constant.
Amniotic fluid surrounds the developing fetus inside the womb and protects the fetus from injury and temperature changes. It additionally lets in for freedom of fetal movement and permits musculoskeletal improvement.
Amniotic fluid is chargeable for: defending the fetus: The fluid cushions the infant from outdoor pressures, acting as a shock absorber. Temperature manipulation: The fluid insulates the child, maintaining it warm and preserving a normal temperature. contamination control: The amniotic fluid carries antibodies.
In the beginning, amniotic fluid is especially water with electrolytes, however, using approximately the 12-14th week the liquid also incorporates proteins, carbohydrates, lipids and phospholipids, and urea, all of which aid in the growth of the fetus.

Answer:
The correct answer would be "Myosin heads attach to sites on actin filaments".
The muscle cell or myofibril consists of two types of protein filaments namely; actin (thin filament) and myosin (thick filament).
The myosin heads attach to the binding sites on the actin filaments and pull it towards the M-line in order to produce contraction.
The hydrolysis of ATP provides energy for this contraction cycle.
The correct answer is option (D) A sandwich is digested and converted to carbon dioxide and water.
Digestion is a catabolic process of breakdown of complex food substances into simpler nutrients releasing energy. In the process of digestion of a sandwich, the carbohydrates are broken down into simpler sugars in presence of enzymes releasing water, carbon dioxide and energy in the form of adenosine triphosphate (ATP). This ATP is the reserved energy currency and also used for the growth, repair and replacement of cells.

<h3><u>Answer;</u></h3>
b). Activation of an upstream guanine nucleotide exchange factor
<h3><u>Explanation</u>;</h3>
- <em><u>When a ligand activates the G protein-coupled receptor, it induces a conformational change in the receptor that allows the receptor to function as a guanine nucleotide exchange factor (GEF) that exchanges GDP for GTPthus turning the G protein-coupled receptor on.</u></em>
- The activated G-protein then dissociates into an alpha (G-alpha) and a beta-gamma complex.
