I think its either, the suns not out, or the temperature decreases
Answer/Explanation:
When cell absorbs light energy it begins <em>photosynthesis </em>(process by which sunlight is transformed into food for the plant). The light energy is absorbed by the <em>chloroplast. </em>Photosynthesis happens and oxygen, water, and glucose are produced. These are transported to the mitochondria where <em>ATP</em> (chemical energy) is released. All that is left is Carbon dioxide and water which are moved back to the chloroplast. This process between the mitochondrion and the chloroplast is cellular respiration.
<h3><u>Answer and explanation;</u></h3>
- This can be done by<u> DNA sequencing which is the process of determining the accurate order of nucleotides within a DNA molecule</u>.
- By doing a DNA sequencing for the two sequences of DNA from the two species it will help compare the number of random mutations which have occurred in a molecular clock in the two species - that is, seeing how different the sequences are.
- This will make it possible to infer how long ago the species diverged.
Species A: GTTGAGCTAGTATGGACC
Species B: GATAAGCTAGTAAGGTCA
These species differ in 5 nucleotides.
This number should be multiplied by the rate of mutations; that is;
5 × 15 million years =75 million years.
