Heterogeneous studies in terms of gender, age, data source, group of comparison, cycling level or modality practiced among others factors showed minor but important differences in results. Despite some controversial results, it has been observed that adult road cyclists participating in regular training have low bone mineral density in key regions (for example, lumbar spine). Conversely, other types of cycling (such as mountain biking), or combination with other sports could reduce this unsafe effect. These results cannot yet be explained by differences in dietary patterns or endocrine factors.
Answer: Carbohydrates like sugar and starch are readily broken down into glucose, which is the body's main energy source. Glucose can be used immediately as fuel or stored as glycogen.

This duct system is slightly a complex structure with proximal convoluted tubule which is segmented into two segments as S1 and S2.</span>
Answer:
The stomata controls the flow of gases in and out of the leaves.
Explanation:
The opening and closing of the stomata controls gas flow in leaves. This controls is necessary to prevent excessive loss of water as vapour from the plant body via transpiration. Usually stomata opens in the day and closes in the night. Each stoma or stomatal wall is flanked by two bean-shaped guard cells, the only epidermal cells with chloroplasts. The wall of the guard cells next to the pore are thicker than those adjacent to the epidermal cells. Here,,the thicker wall cannot stretch as much as the thinner walls.
