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.
Mechanical digestions is usually associated with the mouth. You mechanically chew the food and saliva breaks it down. Chemical digestion occurs in the stomach where stomach acid breaks it down.
Answer:
D
Explanation:
Your brain sends out the commands to the effectors in the body, but the sensors around the body send information to be processed in the brain about equilibrium.
