<span>There are three types of hybrid reproductive barriers. The one described is called hybrid breakdown. In hybrid breakdown as the hybrid organisms continue to reproduce each sequential generation becomes less viable, healthy and loses it's ability to reproduce. The other two hybrid reproductive barriers are hybrid sterility and hybrid inviability. Hybrid sterility results in healthy organisms that can not reproduce at all since thy are sterile. Hybrid inviability results in organisms that are not strong enough to survive and often die while juveniles.</span>
The correct answer is C) It recognizes that no resource or species exists on its own.
<span>Ecosystem-based management acknowledge that no resource, specie or anything in the environment is isolated and each one has an impact on the other.
This helps to provide a more holistic approach and helps in better planning and implementation.</span>
Answer:
The correct answer will be option-B
Explanation:
The environment of the stomach is acidic in nature maintaining value less than seven as it kills the microbes and helps activate the pepsin to digest the proteins.
The acidic nature of the gastric juice does not affect the stomach as the mucosa layer of the stomach secretes mucous and the if the cells get affected then the cells are repaired by the process of mitosis taking in the epithelial cells.
Thus, Option-B is the correct answer.
Answer:
The correct option is C. Rare alleles tend to remain rare even when they are dominant.The distribution of a gene among individuals is determined by mating and environmental factors.
Explanation:
Most people believe that a rare allele would only be recessive. But this is not correct. A rare allele can be dominant. The frequency of an allele to occur in a population will depend on the environmental factors. The alleles which code for traits that are best suitable for living in an environment will be seen in more abundance. The frequency of an allele to occur in a population also depends on the breeding trends of the population.
I think the thalamus is the gateway to the cerebral cortex. Thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the mid brain and has extensive nerve connections to both. Its main function is to relay motor and sensory signals to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation, which is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
