By definition, photosynthesis is a process by which photoautotrophs convert the energy derived from the Sun into usable chemical energy. Light, water, chlorophyll, and carbon dioxide are the basic requirements for this process.
Step 1
Carbon dioxide in the atmosphere enters the plant leaf through stomata, i.e., minute epidermal pores in the leaves and stem of plants which facilitate the transfer of various gases and water vapor.
Step 2
Water enters the leaves, primarily through the roots. These roots are especially designed to draw the ground water and transport it to the leaves through the stem.
Step 3
As sunlight falls on the leaf surface, the chlorophyll, i.e., the green pigment present in the plant leaf, traps the energy in it. Interestingly, the green color of the leaf is also attributed to presence of chlorophyll.
Step 4
Then hydrogen and oxygen are produced by converting water using the energy derived from the Sun. Hydrogen is combined with carbon dioxide in order to make food for the plant, while oxygen is released through the stomata. Similarly, even algae and bacteria use carbon dioxide and hydrogen to prepare food, while oxygen is let out as a waste product.
The answer to this is True. The government controls major aspects of economic production.
Given the above production possibility curve:
- Kate has an absolute advantage in neither goods
- Sarah has the absolute advantage in both goods.
<h3>What is absolute advantage?</h3>
This is the ability of one person or group to do a certain economic activity more effectively than another person or group.
<h3>How do we arrive at the above answer?</h3>
From the PPC curves of both manufacturers, the attached schedule of production which shows how they use 8 hours of labor indicates that:
Kate produces 4 loaves of bread or 8 pieces of cake; while
Sarah produces 12 loaves or 9 pieces of cake.
Given the definition of Absolute Advantage above, it is thus correct to state that:
- Kate has an absolute advantage in neither goods: while
- Sarah has the absolute advantage in both goods.

The repeating decimal 0.625625625 represented as a fraction in its simplest form is 1001001/1600000.
<h3>What is a fraction?</h3>
Fraction simply refers to number expressed as a quotient, in which a numerator is divided by a denominator.
For example, a/b
Given that;
- Decimal number = 0.625625625
- Number in fraction form = ?
First, we rewrite the decimal number as a fraction with 1 in the denominator.
0.625625625 = 0.625625625/1
Next, we multiply to remove 9 decimal places. ( multiply top and bottom numbers with 1000000000 )
0.625625625 = 0.625625625/1 × 1000000000/1000000000
0.625625625 = 625625625/1000000000
Next, we simply, 625 can go through the numerator and denominator.
0.625625625 = 625625625/1000000000 = 1001001/1600000
Therefore, the repeating decimal 0.625625625 represented as a fraction in its simplest form is 1001001/1600000.
