Archy [21]

Answer:

Directional Selection

Explanation:

The type of natural selection that favors one of the extreme phenotypes over the intermediate and another extreme phenotype is called directional selection. Here, the extreme phenotype exhibits better survival and reproductive fitness over the other phenotypic ranges.

In the given example, the frequency of the heat-tolerant allele in microbes is shown to increase under the conditions of higher temperatures of the water of the springs in which they live.

When the temperature of spring water is increased, the frequency of the heat-tolerant allele is reduced and is increased again upon an increase in water temperature.

Since the natural selection favors the extreme phenotype (microbes with heat tolerance) when the spring water exhibits higher temperatures, it is directional selection.

Identify the products of photosynthesis. carbon dioxide and glucose glucose and oxygen carbon dioxide and water light energy and

Eva8 [605]

Answer:

0.17 mole of glucose is formed.

Explanation:

Step 1:

The equation for the reaction. This is given below:

CO2 + H2O —> C6H12O6 + O2

Step 2:

Balancing the equation.

The equation can be balanced as follow:

CO2 + H2O —> C6H12O6 + O2

There are 6 atoms of C on the right side and 1 atom on the left side. It can be balance by putting 6 in front of CO2 as shown below:

6CO2 + H2O —> C6H12O6 + O2

Therefore are 12 atoms of H on the right side and 2 atoms on the left side. It can be balance by putting 6 in front of H2O as shown below:

6CO2 + 6H2O —> C6H12O6 + O2

There are a total of 8 atoms of O the right side and a total of 18 atoms on the left. It can be balance by putting 6 in front of O2 as shown below:

6CO2 + 6H2O —> C6H12O6 + 6O2

Now the equation is balanced.

Step 3:

Determination of the number of mole of glucose (C6H12O6) produced by 1 mole of water.

This is illustrated below:

6CO2 + 6H2O —> C6H12O6 + 6O2

From the balanced equation above,

6 moles of H2O produced 1 mole of C6H12O6.

Therefore, 1 mole of H2O will produce = 1/6 = 0.17 mole of C6H12O6.
