Answer:
The correct option is <u>E. Bring in some elephants of reproductive age from other populations within southern Africa</u>
Explanation:
Inbreeding depression can be described as a phenomenon in which the fitness of a particular kind of species is reduced due to inbreeding of the organisms.
As the Addo National Park contains only a few elephants, hence there are only a few chances of diversification in their breeding patterns. If other elephants are brought into the Park, then there will be more options for breeding and breaking the inbreeding depression.
Answer:
c. moved from one species to another
Explanation:
During lateral gene transfer, one or more genes from one mature, independent organism are transferred to another. Here, the donor and recipient organisms may belong to different species. Lateral gene transfer in prokaryotes occurs by mechanisms such as transformation, conjugation, and transduction. For example, the genes for antibiotic resistance have been spread in the species of bacteria by lateral gene transfer.
Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance
Answer:
Zebra mussels negatively impact ecosystems in many ways. They filter out algae that native species need for food and they attach to--and incapacitate--native mussels. Power plants must also spend millions of dollars removing zebra mussels from clogged water intakes.
Explanation:
it forms covalent bonds by sharing electrons
