By performing photosynthesis, plants create everything they need to build all biomolecules. Is this true? Why or why not?

1 answer:

3 0

Photosynthesis is a series of metabolic reactions by which plants synthesize biomolecules by using sunlight. During this process, plants use simple molecules (H2O, CO2) to create oxygen and chemical energy.

During photosynthesis, chemical energy is stored in the chemical bonds of simple carbohydrates (e.g., glucose).

The statement above IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.

Carbohydrates are biomolecules consisting of Hydrogen, Carbon, and Oxygen.

Plants require Nitrogen, Phosphorous and Sulfur from the soil in order to to create different biomolecules such as proteins (whose building blocks are amino acids) and nucleic acids.

Answer:

the directionality problem

Explanation:

In directionality problems, there are two variables and when these two variables are co-related then it becomes impossible to decide which variable is the cause of the particular problem and which variable is the effect of the problem.

So here there are two variables depression and insomnia but scientists can not determine that out of insomnia and depression which is the cause of the problem and which is the effect of the problem so it is unclear that whether the depression causes insomnia or the lack of sleep causes depression. Therefore this is an example of directionality problem .

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway.

<h3>Further explanation </h3>

Examine the accompanying wind rose diagram. Based on the information shown, determine the correct answers to the following questions.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the color coding and think carefully about the best position for each label when multiple locations seem possible.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway. This relationship explains why planes circle above an airport so they can land in the correct orientation, and why they reorient themselves after taking off in a direction other than the direction they wish to fly. In our example, the longest spoke in the wind rose diagram indicates prevailing winds are coming from the NE and blowing toward the SW. Therefore, the correct orientation for the runway is along this path, with planes taking off in the SW to NE direction. This wind pattern can be found where NE trade winds are located.
