I would say moving at a constant speed
Gravity causes the raindrop to accelerate to the ground at a rate of 10m/s². However, air friction acts against this gravitational acceleration by reducing the rate of acceleration of the raindrops. The higher the friction surface of the raindrops the lower the terminal velocity.
Genotype of the Q gene is homozygous dominant
<u>It is D. 3.5 billion years. </u>The "stromatolites" are the earliest fossils that have been found.
Gastric secretion begins during the cephalic stage and ends during the intestinal phase. The regulation of stomach secretion is divided into three phases which are cephalic, gastric and intestinal. The cephalic stage occurs when the food is been eaten. Gastric secretions are stimulated by three chemicals which are acetylcholine, histamine and gastrin. The gastric phase occurs in the stomach while the intestinal phase occurs in the small intestines.<span />
