The use of chemical as synonymous with toxic, hazardous or poison in some contexts, particularly popular media, is common. 4 This gives rise to a definition of chemical as something synthetic and toxic, and leads to a series of misconceptions such as the possibility of leading a chemical-free life.
Breeding of different branches of the equine family, which does not occur in the wild, generally results in infertile offspring. The combination of sire and dam also affects the offspring phenotype. A zorse is the offspring of a zebra stallion and a horse mare. This cross is also called a zebrula, zebrule, or zebra mule. The rarer reverse pairing is sometimes called a horbra, hebra, zebrinny or zebret. Like most other animal hybrids, the zorse is sterile.
Zygophores are chemotropic aerial hyphae that are the sex organs of Zygomycota, except for Phycomyces in which they are not aerial but found in the substratum. They have two different mating types (+) and (-).n its asexual phase it develops bulbous black sporangia at the tips of upright hyphae, each containing hundreds of haploid spores. As in most zygomycetes, asexual reproduction is the most common form of reproduction.
