However, when hybrids are produced between both species, the gene flow between the two will continue to be impeded as the hybrid males are sterile. Also, and in contrast with the great vigor shown by the sterile males, the descendants of the backcrosses of the hybrid females with the parent species are weak and notoriously non-viable.
The vehicles automatically switch to the combustion engine when more horsepower is required. Unlike fully electric vehicles, not all hybrids need to be plugged into a wall outlet or charging ...
This list includes both regular hybrid electric vehicles and plug-in hybrids, in chronological order of first production. Since Porsche made the first hybrid car in 1899 there have been a number of hybrid vehicles; but there was a marked increase in interest in, and development of, hybrid vehicles for personal transport in the late 1990s.
Plug-in hybrids and electric cars run off lithium-ion batteries and rare-earth element electric motors.Electric vehicles use much more lithium carbonate equivalent in their batteries compared to the 7g (0.25 oz) for a smartphone or the 30 g (1.1 oz) used by tablets or computers.
Researchers from the University of British Columbia have developed a "groundbreaking coating" that could make blood-contacting devices safer. Dr. Jayachandran Kizhakkedathu discusses the benefits.
“The PowerBoost hybrid we tested registered 20 mpg overall, just 1 mile better than the 2.7-liter turbo V6 non-hybrid, even though it costs $3,300 more. At that rate, it would take you 28 years ...
A hybrid animal is one with parentage of two separate species, differentiating it from crossbred animals, which have parentage of the same species. Hybrids are usually, but not always, sterile. [5] One of the most ancient types of hybrid animal is the mule, a cross between a female horse and a male donkey.
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
