Answer:
1. The 2 bases forming each rung of the 'ladder' snap apart. This is caused by an enzyme that passes along the strands, 'unzipping' it
2. Spare nucleotides (in the nucleus of the cell) attach themselves to the 'broken rungs' to repair the break. Each repairing nucleotide is identical to the broken one
3. As each 'broken rung' is repaired, two 'ladders' form, that is 2 identical strands of DNA. The 'repairing' is really the process of replica
Explanation:
Hope this helps!
Answer:
When people lift weights, microscopic damage (microtears) occurs to the myofibrils within the muscle fiber. These microtears stimulate the body's repair response. ... The increased number of myofibrils causes muscle fibers to enlarge, increasing their volume and size.
Explanation:
Mike discovered that the product of cellular respiration are the raw materials of Photosynthesis while the products of photosynthesis served as the raw materials for cellular respiration.
He also discovered that respiration is a catabolic process while photosynthesis is an anabolic process.
Another interesting fact seen by Mike is, the respiration releases energy while photosynthesis takes in energy.
Explanation:
- In the equation of cellular respiration , we can see that glucose and oxygen are utilized in the mitochondrion to produce carbon dioxide , water and chemical energy in the form of ATP.
- Glucose breaks down during cellular respiration .
- Again if we look at the chemical equation for photosynthesis in the chloroplast, we find that Carbon dioxide,which was produced during respiration is utilized along with water in presence of light energy to give out oxygen and Sugar (glucose)
All living organisms have ways of maintaining homeostasis. They have mechanisms for controlling such factors as their internal temperature, water balance, and acidity. Homeostasis is necessary for normal life processes that take place inside cells.
