Answer:
a = increased temperature increases the kinetic energy of the gas molecules.
b = higher temperatures will increase the energy and therefore the movement of the molecules, increasing the rate of diffusion.
Answer:
Exocytosis: It is defined as the process of membrane-bound vesicles fusing with the plasma membrane and later releasing their contents to the extracellular part of the cell.
Endocytosis: It is defined as the process of capturing a particle from outside the cell by the engulfing process with the cell membrane. It is basically two types:
1) Pinocytosis: Cellular drinking.
2) Phagocytosis: Cellular eating.
Answer:
Plus end and kinesin.
Explanation:
Three important cytoskeleton components are microtubules, microfilaments and intermediate filaments. Microtubules are the polymer of tubulin and plays an important role in the movement of cell organelles and its structure.
Microtubules shows the process of polymerization and depolymerization at different ends. The plus end shows the polymerization and minus end shows the depolymerization process. The kinesin protein is required for the process of polymerization.
Thus, the correct answer is option (D).
Answer:
Oxygen and pyruvate.
Explanation:
The krebs cycle is a stage of cellular respiration and occurs in aerobic organisms. In this case, we can say that the Krebs Cycle only occurs in the presence of oxygen, being essential for the completion of cell respiration.
The Krebs cycle only occurs after the completion of glycolysis, as it needs to be initiated by pyruvate, which is a molecule resulting from glycolysis. In this case, in addition to oxygen, the presence of pyruvate is essential for the krebs cycle to occur.
