Is ecological isolation a prezygotic isolating mechanism?
Sure is. How can one mate if an ecological barrier is erected between two biological species? Even something as simple as the time of day can be a barrier to mating.
Why did Darwin's visit to galapagos islands have such an important influence on his devopment of the theory of evolution?
Darwin's visit to the Galapagos Islands was crucial for his development of the theory of evolution because he observed distinct variations in species across the islands, particularly in finches and tortoises. These variations seemed adapted to their specific environments, suggesting a process of natural selection. The unique biodiversity he encountered provided evidence that species evolve over time in response to their surroundings, fundamentally shaping his ideas about adaptation and the mechanism of evolution. This experience led him to formulate his groundbreaking theory, which he later presented in "On the Origin of Species."
Darwin concluded that organisms on the Galápagos Islands?
Darwin concluded that organisms on the Galápagos Islands showed variation from island to island, leading to his theory of natural selection as a mechanism for evolution. He observed unique adaptations in species such as finches and tortoises, which helped support his ideas on how species could change over time in response to their environment.
What is the most powerful defense mechanism?
Fear.
Why are cnidocytes important?
Cnidocytes are important because they contain stinging cells that cnidarians, like jellyfish and corals, use for defense and capturing prey. The specialized structure of cnidocytes allows them to quickly discharge venomous barbs when triggered by touch or chemical stimuli. This defense mechanism is crucial for cnidarians' survival in the marine environment.
Mechanism for when anatomical differences prevent mating?
Mechanical reproductive isolating mechanism
What type of isolation mechanism was important in the formation of Galapagos finches species?
Geographic IsolationSpeciation in the Galápagos finches occurred by founding of new populations, geographic isolation, gene pool changes, reproductive isolation, and ecological competition.
Which reproductive isolating mechanism is mostly restricted to animals?
The reproductive isolating mechanism that is mostly restricted to animals is behavioral. Reproductive isolation is also referred to as hybridization barriers.
What are isolating mechanisms?
Intrinsic mechanism is defined as an obstacle to interbreeding. Examples of intrinsic isolating mechanism includes behavioral and structural incompatibility. An example of extrinsic is geographical barrier.

Which reproductive isolating mechanism is primarily restricted to animals?
The behavior isolation is the reproductive isolating mechanism that is primarily restricted to animals. In behavioral isolation, animals have unique courtship rituals such as mating dances and breeding calls.
What is the mechanism of urine formation?
The mechanism of urine formation takes place by three steps. they are glomerular filtration, tubular reabsorption and tubular secretion.
What is an example of a postmating mechanism that limits formation of a hybrid offspring?
hybrid inviability
How we Write the mechanism of the formation of the neutron ion?
A "neutron ion" doesn't exist.
How can you use mechanism in sentences?
The mechanism of doing things right is very important. Mechanism is a word that denotes the way to do.

How is The presence of a refuge is an important mechanism?
The presence of a refuge is an important mechanism that stabilizes otherwise unstable predator-prey interactions.
