The common name of this organism is hydra.
<u>Explanation:</u>
Hydra is a fresh water organism and belongs to the phylum Cnidarian. They have tentacles around their body that enables locomotion as well as protection from prey. Hydra has the ability of regeneration and the asexual mode of reproduction in hydra is budding.
In the budding process, a small bud develops in the parent body and the bud after maturation gets detached from the parent body and grows into a new individual. Sexual mode of reproduction is also found in hydra.
Answer:
As the climate gets hotter, the glacier melts hence gets smaller, vice versa for colder temperatures.
Explanation:
Answer:
A
Explanation:
The answer should be A because respiration is a chemical process
The correct option is this: TWO DRAGONFLY SPECIES REGULARLY MATE BUT THEIR GAMETES ARE INCOMPATIBLE.
In biology, there are different types of reproductive barriers, one of these is prezygotic barrier. A prezygotic barrier is a kind of mechanism that prevent reproduction from occurring by blocking fertilization. In this case, the concerned species will be mating together, but their gametes will not be compatible and thus, zygote will not be formed.
A postzygotic barrier on the other hand is said to occur when the reproduction process is blocked after the formation of zygote or after fertilization has taken place. A good example of this is an hybrid mule that is sterile and can not reproduce.
