Answer:
The correct answer is option a, that is, sympatric speciation.
Explanation:
Speciation, which takes place when two groups of similar species live in a similar geographical location, however, they evolve distinctly unless and until they no longer interbreed and are regarded as different species is termed as sympatric speciation.
Sympatric speciation is not similar to other kinds of speciation, in which the formation of a new species takes place when a population gets differentiated into two groups because of migration or geographic barrier. The sympatric speciation can be witnessed in various distinct kinds of species. Thus, the given case of monkeys is an illustration of sympatric speciation.
Answer:
Based on this, you know that Sampson is using the whistle as a <u><em>secondary </em></u> reinforcer to train the dolphins.
Explanation:
Secondary Reinforcement can be described as a condition in which a stimulus initiates a behavior after being previously associated with a primary reinforcer. A secondary reinforcement is a stimulus that satisfies basic survival instinct such as food, drinks, and clothing.
The same phenomenon was being used by Samson to train his dolphins to perform tasks. The dolphins enjoyed the sound of the whistle because previously that sound was paired to them getting their food.
Answer:
The correct answer is option B. maculae/ static equilibrium.
Explanation:
Maculae are mechanoreceptors present inside the saccule and utricle specialized for the static equilibrium detecting. Maculae use hair cells to find out the movements of the otolithic membrane occurs, which is the surrounding membrane of the macula.
The sense of the position of the head to determine the stability and posture is static equilibrium and it is determined by the maculae.
Thus, the correct answer is option- B. maculae/ static equilibrium.
