Answer: DNA growth does not occur
Explanation:
Here, the cell has grown, the DNA has been replicated (this takes place in the S phase of interphase) and its almost time for the cell to divide. Basically, what occurs during the G2 phase (Gap 2 phase of interphase) includes duplication of all proteins and organelles needed later during the process of cell division. Some of these includes assembly of microtubles will later for the spindle structure that that helps in the separation of chromosomes during the M phase but these are produced during the G2 phase.
The cells also continue to increase/grow in size and the volume of the cytoplasm also increase in this phase. There is also a checking where the cell needs to check for the structures and components and to also ensure that they are all present
Answer: B. under use; it is a scarce resource.
Explanation:
Early settlers in the town of Dry Gulch drilled wells to pump as much water as they wanted from the single aquifer beneath the town. (An aquifer is an underground body of water.) As more people settled in Dry Gulch, the aquifer level fell and new wells had to be drilled deeper at higher cost.Residents of Dry Gulch have a private incentive to under use water because it is a scarce resource.
Answer:
In explanation.
Explanation:
Relationship between photosynthesis and cellular respiration.
-Both involve in the production of energy
-Both involve the exchange of gases
-Both the process takes place in cell organelle which was considered as endosymbiotic organism. They are chloroplast and Mitochondria, Photosynthesis takes place in the Chloroplast whereas respiration takes place in mitochondria.
-At critical condition both have an alternate pathway.
Extra: differences between photosynthesis and cellular respiration.
-Photosynthesis takes place in the chloroplast, whereas respiration takes place in mitochondria.
-Photosynthesis involves the production of carbohydrate and respiration involve breaking of carbohydrate.
-Photosynthesis occurs only during the presence of sunlight whereas respiration occurs all the time.
-In the photosynthesis process Oxygen is released whereas in respiration Oxygen is utilized.
The two cells of the similar shape, and size have different levels of the ongoing metabolic activity. On one hand, the cell a is metabolically quiet, which means that no energy consuming chemical reactions are taking place in this cell. On the other hand, the cell b is actively consuming the surrounding oxygen. In this scenario, the oxygen will more quickly diffuse into the cell b because the diffusion gradient for oxygen in this cell is steeper than in the cell a.
Hence, the blanks can be filled with 'b and the diffusion gradient is steeper' respectively.
