Answer: invivo
A person has a genetic condition that affects his ability to produce melatonin, which is a hormone that is produced in the brain and tells the body it’s time to sleep. To correctly diagnose this disease, the doctor must collect cell samples invivo to analyze his DNA.
Explanation:
Invivo refers to the within the living organism. Since DNA is located inside the nucleus of brain cells, and it regulate gene expression; then the doctor must analyze the genetic information contained in the DNA of brain cells of the person having trouble with secreting melatonin ( the sleep/wake hormone), if any alteration has occurred.
Thus, based on the location of DNA, the doctor must collect cell samples invivo for analysis

Answer: Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Answer:
When change occurs in the population of one species affect the entire ecosystem. If the population of herbivores goes very high then all the producers i. e. Plants are eaten by the herbivores and no vegetation is available for other animals and they will die because of hunger.
For example, if the population of deer increases in a forest ecosystem, so all plants are eaten by the deer and no plants are available for another herbivores.
