Answer:
A.
Explanation:
The arctic soil is so cold that the ground beneath the tundra surface remains frozen all year. This permanently frozen ground is called permafrost. Each summer, when the sun warms the tundra surface, the top few inches of soil thaw. This melted part is called the active layer.
Because the Epiglottis covers the Larynx
It should be 32 ATPs, since the electron transport chain produces 34(38) ATPs, and the citric acid cycle produces only 2 ATPs. 34-2=32
Answer:
The temperature below the clouds does not affect the temperature of the precipitation falling. The sleet would change state to liquid water and would fall as rain drops from the sky. ... If the colder air were replaced with warm air, the sleet pellets would change to snowflakes in a solid state.
Answer:
The complete breakdown of glucose in the presence of oxygen occurs in two stages: glycolysis and citric acid cycle. The first of these stages occur in the cytoplasm of the cell, and the second stage occurs in organelles called Mitochondria.
Explanation:
The breakdown of glucose occurs in two stages. The first stage occurs inside the cytoplasm, it is called glycolysis. when a molecule of glucose undergoes glycolysis, the following are produced:
2 ATP (Adenosine triphosphate) molecules;
2 water molecules;
2 pyruvate molecules and;
2 NADH (Nicotinamide Adenine dinucleotide) molecules
The second stage occurs in an organelle called Mitochondria, it is called citric acid cycle or tricarboxylic acid or Kreb's cycle. In this stage, the two pyruvate molecules from the glycolytic cycle are reduced to carbon(iv)oxide. The following are produced:
2 ATP molecules;
6 NADH molecules;
2 FADH2 (flavine adenine dinucleotide) and;
4 molecules of carbon(iv) oxide.
The NADH and FADH2 molecules are used in the electron transport chain generates as much as 28 ATP molecules.
