Neurotransmitters can affect postsynaptic cells by causing molecular changes in the cells.
The term "chemical messengers of the body" is frequently used to describe neurotransmitters. The nervous system uses these molecules to send information between neurons or from neurons to muscles. A neurotransmitter influences a neuron in one of three ways: excitatory, inhibitory or modulatory.
When a stimulus is potent enough, the chemical messenger neurotransmitter is transferred into the nerve impulse. If it is powerful enough, it will reach the postsynaptic cell and affect the structure of the neuron. And when signal transduction happens, everything mentioned above is completed.

Answer: Directional Selection.
Explanation: Earlier the ancestors of the giraffe had shorter neck as compared to the giraffe of the present time.

Answer:
reduction in birds skeleton
Explanation:
The reduction in a bird's skeletal weight is largely a result of hollow construction of the skeleton. The fusion or loss of individual bones reduces the number of movable joints in the bird's skeleton, making it rigid and better adapted as the internal framework of a flying machine.
According to Rosa Beth moss Kanter, segmentalist organizations are characterized by the compartmentalization of problem-solving.
<h3>What is a Organization?</h3>
An organization is a group of individuals working together to achieve predetermined goals. It can be viewed as a social structure that includes all formally recognized human interactions. The organization includes task alignment with respect to the company's ultimate aim and the division of labor among personnel.
It can also be referred to as the second-most significant managerial activity, coordinating employee efforts, acquiring resources, and fusing the two in support of organizational objectives.
Goals are the focus of organization, which works to achieve them through careful planning and activity coordination. It is based on the idea of task division and establishes a hierarchy of authority and responsibility among the organization's members.
