<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>
Answer:
The proper matching is given below.
Explanation:
Predation Typical plant defence include(thorns,sticky substances) and chemicals(toxin,bad tastingchemicals) adaptation.
Competition When individuals fight for a common resource,the weaker one experience loss or affected adversely.
Disease pathogens can be transmitted to host by direct contact between hosts o through soil,water,air or any other surface.
Symbiosis This interaction is of three types : mutalism,Commensalism and parasitism.
The R group should have the ability to form hydrogen bonds.
The R-group take a lot of different chemical forms and can
be acidic, basic, polar or non polar. Amino acids that are either acidic or basic
consequently have either positive or negative charge. These types of R-groups
are stabilized when surrounded by water.
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.
