Explanation:
Parasitic
Competition
Mutualism
Answer: Comensulism
Commensalism is being displayed From the video Clownfish and Sea Anemone Partnership
Explanation:
From the video Clownfish and sea Anemone Partnership there is a significant relation that can be seen from the statement itself too and that is sign of symbolism.
The relation of symbol is used for the sea anemone. So, both Clown fish and Anemone are held to be very beneficial whenever these two fishes are kept together in presence of each other.
So, it can be said clown fish and sea anemone have a very deep relation between each other.
2) Tetany
3) relaxation
4) repolarization
Answer:
Tetany
Explanation
The refractory period in the heart refers to the shortest interval between consecutive contraction conducted impulses out of the cardiac muscle.
It is important because it allows adjustments to stimuli and limits amount of action potential sent per minute.
Without a plateau extending the refractory period in the cardiac muscles.
Sarcomeres might be stimulated to contract instead of relaxing leading to sustained contraction also called Tetany.
Tetany is an involuntary muscle cramp or contraction caused by overly stimulated nerves.
Answer:
Global climate models usually work by managing the planet as a set of connected boxes because this facilitates the management of the calculations applied in a climate system that is dynamic, variable and complex, which is due to the fact that there is not an equal pattern of climate in each area of the planet.
Explanation:
Climate models have been designed to show the dynamics of the planet's climate and what can be expected from the changes that occur in the future.
The scientific basis of a climate model is physical phenomena and chemical reactions to which a series of differential calculations are applied to determine the behaviour of:
Global climate models usually divide the planet into sections -such as boxes- making the calculations in each sector, as well as the interaction of each section with the adjacent sections, which greatly facilitates making the differential calculations, showing the climate at a given time and making predictions of future climate behavior.
It is important to mention that a climate model also explains the changes that occur in the climate due to human activity, which is different in each region of the world.

Answer:
Mitosis.
Explanation:
Mitosis is the process by which body cells divide. is the process by which body cells divide. The cells in multicellular organisms undergo mitosis repeatedly. The cells produced by mitosis are used for growth. They are also used to repair body tissues and replace worn-out cells. The image shows the input and output of mitosis. Notice that two cells are produced when one cell undergoes mitosis and cell division. Both cells produced are identical to the starting cell.
-Therefore, mitosis is the correct answer.
B) The enzymes of glycolysis are located in the cytosol of the cell.
C) Glycolysis can operate in the complete absence of O2.
D) The end products of glycolysis are CO2 and H20.
E) Glycolysis makes ATP exclusively through substrate-level phosphorylation.
Answer:
D
Explanation:
The end product of glycolysis is pyruvate. This process occurs in the cytosol of the cell in the absence of oxygen and has a net ATP production of 2 and 2 NADH. When there is no oxygen, the pyruvate is converted to lactic acid. When there is oxygen , the pyruvate is channeled to the Krebs cycle in the mitochondria where it is used to produce more ATP. The formation of ATP in glycolysis is powered by the energy in the bonds of the molecules (substrate-level phosphorylation). This is unlike in Krebs cycle where most of ATP are formed through oxidative phosphorylation. The end products of Krebs cycle is CO₂ and H₂O.
All of the following statements about glycolysis are true except the one that states- The end products of glycolysis are CO2 and H2O. So the correct option is option D.
The glycolysis process can take place when there is oxygen present (aerobic) or when there is no oxygen present (anaerobic). Pyruvate is transformed into lactic acid in anaerobic conditions. The fact that glycolysis occurs widely in other species suggests that it is an old metabolic pathway.
Glycolysis in most cells takes place in the cellular cytosol. The process of glycolysis can be divided into two stages: the investment stage, in which ATP is initially consumed, and the yield stage, in which more ATP is eventually produced.
