<h2>Postzygotic isolation </h2>
Explanation:
In the given information of edible frog both male and female hybrids exist, but when they mate among themselves, they cannot successfully produce offspring which defines that postzygotic isolation exists between the two frog species
- Postzygotic isolation prevents the formation of fertile offspring
- Before the postzygotic isolation can happen, there must be an offspring born from a male and female of two different species
- This means there were no prezygotic isolations, such as the fitting together of the sex organs or incompatibility of the gametes or differences in mating rituals or locations, that kept the species in reproductive isolation
- The offspring of two different species known as a hybrid is not always viable
- Sometimes, they will self-abort before being born and other times, they will be sickly or weak as they develop
Answer: An enzyme's shape is determined by the sequence of amino acids in its structure, and the bonds which form between the atoms of those molecules. Different types of enzymes have different shapes and functions because the order and type of amino acids in their structure is different.
<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.
