Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.

Answer:
Active Transport
Explanation:
Active Transport is moving substances from lower concentration to a higher concentration.
It depends if it is a carrier or not, and if the trait is recessive or dominant trait
It is regulated by peristaltic movements. Then the pyloric sphincter will act as a valve at the junction between the stomach and duodenum, controlling the flow of chyme into the small intestine.
Answer: Incomplete Dominance
Explanation:
Incomplete Dominance occurs when an heterozygous phenotype, different from the two parents homozygous phenotypes is expressed in the OFFSPRING.
FOR EXAMPLE: A pure breeding Red flower (RR) plant crossed with a pure breeding White flower (rr) plant and PRODUCES offspring with PINK flowers (Rr). This is Incomplete Dominance.
