Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.
Answer: a. Blood and mucus in the stools.
Explanation:
Diarrhea is a gastrointestinal problem. It is associated with the symptoms of loose stools, cramps, vomiting, fatigue, and stomach pain. The diarrhea usually last for few days to week. It is also associated with the signs of dehydration due to loss of fluid through loose stools like stretchiness in skin, loss of color of skin, and fast heart rate. The diagnostics of diarrhea can be done by examining the blood and mucus in the stool.
