Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes an
d ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures? A. Water molecules are attracted to the surface that has a charge B.Water expands when it freezes, so solid water is less dense than liquid water C.It takes a large amount of energy to increase the temperature of the water D.The positive charges of water’s hydrogen atoms are attracted to the negative charge of its oxygen atoms
B. Water expands when it freezes, so solid water is less dense than liquid water
Explanation:
The molecules of water expands or increases in volume when it is freezed i.e. at a low temperature. This allows the solid state of water (ice) to be less dense than the liquid state (water). Hence, because ice is less dense than water, IT FLOATS. Therefore, in a water body whose temperature is low, the ice component floats on the surface, with liquid water beneath.
Due to this DENSITY property of ice (low) and water, aquatic organisms like fishes are able to survive and live just fine beneath a water body covered with ice. Note that, oxygen is trapped in the liquid portion of the water body underneath the ice covering.
The statement Bonds in the hydrogen peroxide are weakened in catalase's active site, allowing the chemical reaction to occur is the answer. Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water.
A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.
Patent ductus arteriosus occurs when the normal fetal circulation conduit between the pulmonary artery and the aorta fails to close and results in increased pulmonary blood flow. The clinical manifestations of patent ductus arteriosus include; Murmur; wide and bounding pulse pressure, Asymptomatic Heart failure.
