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.
Answer:
In other words, science is one of the most important channels of knowledge. It has a specific role, as well as a variety of functions for the benefit of our society: creating new knowledge, improving education, and increasing the quality of our lives. Science must respond to societal needs and global challenges.

Answer:
First filial generation.
Explanation:
Mendel is known as the father of genetics. He formulated the law of segregation and law of independent assortment by working on the pea plant.
The Mendel first crossed the pure breed line parents and obtained the first filial generation. The F1 generation is obtained by the cross breeding of the parental generation.
Thus, the correct answer is option (D).
Answer:
Waxes does't contain fatty acids,glycerol and a phosphate group.
Explanation:
Car wax and bee wax contain ester bonds, fatty acids and long chain hydrocarbons but they don't possess fatty acid, glycerol,and a phosphate group.
