Lord howe island is a volcanic island in the tasman sea that is about 11 km long and 2.8 km wide. the island has two species of palm trees, howea forsteriana and the more abundant howea belmoreana. the two species do not interbreed even when they grow very close to each other. which evolutionary process is not occurring in the described scenario?

OPTIONS:

A. Genetic drift of Howea forsteriana  B. Natural selection of adaptive traits in both species  C. Gene flow between the two species  D. Mutations in Howea belmoreana

C. Gene flow between the two species

Explanation:

One of the important evolutionary processes that drives evolution among species population is gene flow. Gene flow refers to the transfer of genes from one population to another through migration and reproduction, whereby new gene versions from one population are introduced into the other, and vice versa. genetic materials are exchanged between two the two populations thereby causing genetic variation.

Therefore, the inability of howea forsteriana and howea belmoreana to interbreed is most likely caused by lack of gene flow between both species.

Gene flow is the evolutionary process that is not occurring in the described scenario.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
