Answer:
Wetland reduction has caused a decrease in the absorption zones for excess water. If the excess water cannot be absorbed by the soil, it increases the incidence and magnitude of flooding.
Answer:
If a DNA molecule has 30% Adenine the percentage of the other bases is Thymine: 30% Cytosine: 20% Guanine: 20%.
Explanation:
When the percentage that a base has in a DNA molecule is given, the percentage of the other bases can be known using the Chargaff's base pair rule.
A DNA molecule has the information of the genome of a living being, according to a specific sequence of its nitrogenous bases adenine, guanine, cytosine and thymine.
Chargaff was able to establish that in a DNA molecule the ratio of purine : pyrimidine of 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, taking into account the complementarity of bases.
Taking into account the law of the base pair, if in a DNA chain there is 30% of Adenine, in the molecule there is:
- <em>Adenine 30%.
</em>
- <em>Thymine 30%.
</em>
- <em>Cytosine 20%.
</em>
- <em>Guanine 20%.
</em>
- <em>Total ..... 100%
</em>
In this case, the <u>Chargaff rule is useful to determine the percentage of nitrogenous bases that exist in a DNA molecule, knowing the percentage of a single base</u>.
The amount of oxygen produced can be quantified in order to determine the rate of photosynthesis. Elodea leaves are divided into little pieces, and the cut ends are put into the funnel's stem.
<h3>What did Elodea's bubbles in this experiment represent?</h3>
The bubbles that you observe rising from an elodea cutting's leaves are actually a result of the photosynthesis process. In some types of algae and in plants, photosynthesis takes place. In the process, light energy is changed into a sort of chemical energy that is then stored as sugar.
<h3>What substance did we use to examine whether photosynthesis existed in Elodea?</h3>
To test whether photosynthesis and/or other processes are occurring, you will conduct experiments using the dye Phenol Red in this exercise. In Elodea plants, cellular respiration is taking place. The experiments look into how light affects these processes.
