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?
Hybridization is the process through which two species can mate with each other and produce fertile offspring thus creating a new species.
This is not happening with the two palm species on the island. This may be due to prezygotic barriers that prevent these two species from mating and producing a zygote (fertilized egg cell). In essence these barriers prevent any gene flow between the two species.
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
Answer:
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.
The enzyme function best at a specific temperature.
Explanation:
Enzyme activity is affected by temperature. Each enzyme has a specific temperature
range in which it works most effectively. Most biological enzymes present in the human body have an ideal temperature range of around 98.6 degrees.
They both provide structural support, but only insulin is a carbohydrate. They both store energy, but only glucagon is a carbohydrate. They are both hormones that regulate blood-sugar levels.
Some otters live in large groups while others live completely alone or with only one or two others. They like to live in groups that are up to 100 in size called rafts.
