Design speeds for frontage roads are a factor in the design of the roadway. For consistency, design speeds should be used that match values used for collector streets or highways. For urban frontage roads, the desirable design speed is 50 mph [80 km/h] and the minimum design speed is 30 mph [50 km/h].
Different plants reproduce in different ways. Some plants reproduce asexually, others do use a type of sexual reproduction. Flowering plants in particular reproduce both sexua â¦ lly and asexually. Reproduction in flowering plants involves the production of gametes, the transfer of the male gametes to the female ovules is through pollen.
plants can reproduce by sending out shoots called runners. New plants grow from the runners, getting nutrients from the parent until the roots of the new plant are established. Plants can spread quickly this way. This form of asexual reproduction allows plants to reproduce even when conditions are not right for the germination of seeds. 4 3 2 1 fruit.
