A graph titled "Average plant height (cm) vs. Concentration of sodium phosphate (mg/L)" shows an upward-sloping line that reache
vovangra [49]

Answer:

A. Average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

Explanation:

The graph in the attachment section portrays the average height of plants (cm) on the y-axis plotted against the concentration of sodium phoshate (mg/L) on the x-axis. Based on the observation of the result in the graph, an increase in the concentration of phosphate caused an increase in the average plant height (as depicted by the upward-sloping line).

However, the plant's average height didn't go beyond 35cm despite an increase in concentration of phosphate. This is because the plants has reached a maximum possible height i.e. a height climax. Hence, they cannot grow taller than 35cm no matter the amount of external nutrients (sodium phosphate) supplied.

Therefore, the noticeable trend that can be used to make a conclusion is that average plant height increases with an increase in the concentration of sodium phosphate until the plants reach a maximum possible height.

AveGali [126]

Answer:

Substrate-level phosphorylation, which is a process of forming ATP by the physical addition of a phosphate group to ADP can take place in the cytoplasm during glycolysis or inside the mitochondrial matrix during the Krebs cycle.

Explanation:

Substrate-level phosphorylation is a metabolic reaction that results in the formation of ATP or GTP by the direct transfer of a phosphoryl (PO3) group to ADP or GDP from another phosphorylated compound.
