The calorie expenditure for road cycling and mountain biking can vary based on factors such as intensity, terrain, and duration. Generally, road cycling on flat terrain at a moderate pace can burn around 400-600 calories per hour, while mountain biking on varied terrain with hills and obstacles can burn around 500-800 calories per hour. The higher calorie expenditure in mountain biking is due to the increased effort required to navigate the challenging terrain and obstacles. Overall, mountain biking tends to result in a higher calorie expenditure compared to road cycling. **

Genetically determined hair length is determined by the length of the anagen phase of the hair growth cycle. The anagen phase is the active phase of hair growth, during which the hair follicles produce new hair cells. The length of this phase is determined by genetics, with some individuals having a shorter anagen phase resulting in shorter hair, while others have a longer anagen phase leading to longer hair. Additionally, factors such as age, hormones, and overall health can also influence hair length. **
