B, ocean trenches are formed after a underwater volcano has erupted.<span />
Answer: Hydrogen-3 or tritium as it is commonly called, has a half life of 12.32 years. If you start with 20 grams of it, how much will remain after 25 years? Ending Amount = Beginning Amount / 2 (time / half-life) Ending Amount = 20 / 2 (25 / 12.32) Ending Amount = 20 / 2 (2.0292) Ending Amount = 20 / 4.0818. Ending Amount = 4.8997 grams
Explanation:
Lava flows are typically finer grained (i. e. the rock is made up of smaller mineral grains) than intrusive igneous rocks because the extrusive magma cools quickly so the mineral grains do not have time to grow.
When lava comes out of a volcano and solidifies into extrusive igneous rock, the rock cools very quickly. Crystals inside solid volcanic rocks are small because they do not have much time to form until the rock cools all the way, which stops the crystal growth. Magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere. Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture.

Answer:
Why would newborns be cashing in so many red blood cells?
The possibe sources for the hematocrit are influx of RBC from other sources to the Fetus. e.g., leakage of RBC from the twin child in case of twin pregnancy, possible overproduction of RBC in the fetus,Leakage of some RBC through the umbilical cord to the child close to delivery.
Why would noenates need so much antioxidants
The increased oxidative stress in neonates with Jaundice, leads to loss of antioxidants and ascorbic acids.The loses disrupted their metabolism and therefore the natural ability to fight the oxidative stress.
Consequently,increase in the oxidative stress couple with lack of antioxidant leads to neural cell death.
Therefore, antioxodant is needed to prevent neural cell death and to withstand oxidative stress.
