Answer:
geographical isolation
Explanation:
Reproductive isolation is a process of evolution that ensures that members of different species are incapable of mating and when they do, such mating do not result into any offspring or leads to the production of invalid offspring.
There are two mechanisms of reproductive isolation:
- Pre-zygotic mechanisms prevents fertilization between two different species and these include habitat isolation, mating seasons, mechanical isolation, gamete isolation, geographical isolation and behavioral isolation.
- Post-zygotic isolation prevents the products of fertilization from becoming valid and this include hybrid inviability, hybrid sterility and hybrid breakdown.
<em>Geographical isolation involves the existence of geographical barriers between two populations such that there cannot be mating between the two. The two populations eventually evolve to become different species.</em>

<span>Diet drugs such as lorcaserin and
phentermine-topiramate help people in losing weight by reducing food intake. These
drugs are affecting the central nervous system, which act as an appetite suppressant
where a person will not feel hungry or has lesser urge in eating does reducing

Answer:
An ecological community is made up of all the populations of all the different species that live together in a particular area. The interactions between different species in a community are called interspecific interactions, inter- means "between".
The child is more susceptible to diseases than the father because the father has already gained a slight immunity towards the lead by loving in the house longer than the child (assuming the father has lived in the house longer)
