Answer:
1. e. Hybrid performance
2. d. Zygote death
3. a. Gametic isolation
4. f. Ecological isolation
5. g. Behavioral isolation
Explanation:
Hybrid performance is a postzygotic isolation mechanism associated with the ability to produce hybrid offspring, which are adaptively less fit than their progenitors (for example, in this case, hydric stress is a limiting factor for the viability of the hybrids). Zygote death is another postzygotic barrier where the zygote parents' genes fight one another and thus impair the development of the hybrid zygote, causing its death. Gametic isolation is a prezygotic isolation mechanism associated with the incompatibility between female and male gametes (i.e., egg and sperm in animals), which join to form a viable zygote. Ecological isolation, also known as habitat isolation, is a reproductive prezygotic barrier caused by the separation of organisms because they live in different areas or have different ecological/ environmental requirements. Finally, behavioral is another prezygotic barrier where closely related species have different mating rituals. Behavioral isolation is a common practice in many species of invertebrates (such as, for example, arachnids).
Answer: The plant becomes self-sufficient when leaves grow onto it.
Explanation: The leaves will start photosynthesis instead of the Cotyledons providing nourishment for the seed.
A vector of a zoonotic pathogen differs from a host of the pathogen in that it is not affected by the pathogen.
<h3>What are vectors and pathogens?</h3>
Vectors are organisms which serve as carriers of disease-causing organisms known as pathogen. Vectors usually serve as transport or transit mechanisms by which diseases spread.
Pathogen are organisms that cause disease. A zoonotic pathogen is a pathogen that can move from non-human animals to humans.
The vector of a zoonotic pathogen differ from a host of the pathogen in that the vector is not affected by the pathogen and the vector is also non-human.
