Answer:
The options
A. the postzygotic barrier called hybrid inviability
B. the postzygotic barrier called hybrid breakdown
C. the prezygotic barrier called hybrid sterility
D. gametic isolation
The CORRECT ANSWER IS A.
A. the postzygotic barrier called hybrid inviability
Explanation:
Postzygotic barrier is a mechanism that hinders reproduction after fertilization and zygote development. Hybrid inviability occurs when a mating between two organism produces a hybrid that can't strive past the embryonic stages.
In Reduced Hybrid Viability there is a lower tendency to survive for individuals whose parents possesses incompatible genetics, which may have result from sexual union of these parents from varying species.
These two frog species in this case study can be separated through the mechanism of the postzygotic barrier called hybrid inviability.
<span>Nerve cells send electrical impulses along the axon. When these impulses reach the end of the neuron, they cause a release of neurotransmitters across the synapse.
</span>The axon is part of the neuron (nerve cell that carries messages), as well as dendrite. Axons pass the nerve impulses on to other cells, while dendrite <span>receive nerve impulses from other cells. </span><span>The place where the axon of one neuron meets the </span>dendrite<span> of another is called a </span>synapse.

Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
