Phytoplankton
Phytoplankton are the main organisms responsible for oceanic photosynthesis. These one-celled plants obtain most of their carbon dioxide not from the air but from the depths of the ocean. Much of the oxygen they produce eventually makes its way into the atmosphere, however.
Answer:Adaptation in Darwins Finches. Beak depth, which is correlated with body size and the ability to crack larger seeds, varies according to drought conditions: plants produce fewer, harder seeds in dry years and more, softer seeds in wet years. Only larger birds with deeper depths survive in drought years.
Explanation:
Cellular respiration is the process of breaking down food such as glucose into carbon dioxide and oxygen. During the process, cellular respiration also releases energy in the form of ATP (adenosine triphosphate) for use by all energy consuming activities of the cell. It is found in the simultaneous process of Gycolysis and Kreb’s cycle. Glycolysis is the breakdown of glucose to two pyruvic acids. These two pyruvic acids will be used for the production of carbon dioxide and water in Kreb’s cycle.
Answer: C) gas; liquid
Explanation: There are three states of matter: solid, liquid and gas. Water can exist in these three states. Water is a liquid but when heat energy is applied to it, the temperature rises until it reaches its boiling point where it begins to boil and as water boils, it changes to gaseous state i.e., it turns to vapor. When heat is removed, the temperature decreases and the vapor condenses to liquid and if the heat removal continues, the temperature continues to drop until it reaches its freezing temperature (0°C) where it changes from the liquid to ice (the solid state).
