It doesnt show anything but the question??
Answer:
Tommie Lee Andrews was convicted of defilement in November 1987 and sentenced to 22 years in jail based on both fingerprint analysis and DNA typing, making him the first person in the United States to be convicted based on DNA evidence.
Explanation:
Just like the fields near Mt. St. Helen's returned back after a few years of ashes, many ecosystems find their way through the aftermath of a disaster.
Answer:
Photosynthesis takes place through several steps which occur during two stages: the light phase and the dark phase.
Explanation:
In the light-dependent process, which takes place in the grana, the stacked membrane structure within chloroplasts, the direct energy of light helps the plant to make molecules that carry energy for utilization in the dark phase of photosynthesis. The plant uses light energy to generate the co-enzyme Nicotinamide adenine dinucleotide phosphate, or NADPH and ATP, the molecules that carry energy. The chemical bonds in these compounds store the energy and are used during the dark phase
The dark phase, which takes place in the stroma and in the dark when the molecules that carry energy are present, is also known as the Calvin cycle or C3 cycle. The dark phase uses the ATP and NADPH generated in the light phase to make C-C covalent bonds of carbohydrates from carbon dioxide and water, with the chemical ribulose biphosphate or RuBP, a 5-C chemical capturing the carbon dioxide. Six molecules of carbon dioxide enter the cycle, which in turn produces one molecule of glucose or sugar.
Answer:
common ancestor
Explanation:
A single specie from which other organisms have descended is called a common ancestor.
All descendants which are further generations can trace their origin from this ancestor.
- Two or more descendants can trace their origin to an ancestor.
- Most times, in a family tree, the common ancestor is usually placed on top.
- Several descendants can have just a single ancestor.
