Answer:
B. only the animals living in water
Answer:
Some people offer more prejudice on the sexual orientation because sexual orientation like gay marriages were not seen in the world before. Before the 21st century, the same- sex marriage was never seen or heard about. So, today people display more prejudice regarding this issue because sexual orientation began in the 21st century. Many people are of the view that this same sex marriage is not traditional and hence it is not right morally. While others believe that every person has the right of freedom and this is their civil right to do what they like.
The discrimination based on race and gender has been an issue from the start of human lives. Almost every country has a history which shows race and gender discrimination. Hence, though majority of the people today are against this but still is is not as a hot and new topic for prejudice as the topic of sexual orientation is.
Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
<span>B is the right answer. Gentoo and Emperor penguins employing different mating rituals is an example of behavioral isolation.
