One becomes dependent on smoking when they develop a physical and psychological reliance on nicotine. This can happen after smoking regularly for a period of time, as the body becomes accustomed to the presence of nicotine and craves it when levels drop. Dependence can also be fueled by the habit of smoking in certain situations or to cope with stress, leading to a psychological need for cigarettes. Overall, dependence on smoking can develop gradually over time as the body and mind become more reliant on nicotine. **

Weather-dependent activities are those that are directly impacted by daily weather conditions, such as outdoor sports, gardening, and beach outings. Climate-dependent activities, on the other hand, are influenced by long-term climate patterns, such as agricultural practices, seasonal tourism, and energy consumption. Both types of activities require people to adapt and plan according to the prevailing weather or climate conditions. **

Being dependent on a girl means relying on her for emotional support, validation, or decision-making.

It's important to consider the dynamics of the friendship and the individual needs of each person involved. **

Causality is not inherently time-dependent. Causality refers to the relationship between cause and effect, and it can occur at any point in time. Events in the past can cause effects in the present, and events in the present can cause effects in the future. The concept of causality is not limited to a specific point in time, as it can occur across different time frames. Therefore, causality is not inherently time-dependent. **

Dependent clauses are groups of words that contain a subject and a verb, but they cannot stand alone as complete sentences. They rely on an independent clause to form a complete thought. Dependent clauses often begin with subordinating conjunctions such as "because," "although," "while," "if," and "since." These clauses add additional information to the independent clause and help to create more complex and nuanced sentences. **

Frequency-dependent selection is a type of natural selection where the fitness of a particular phenotype depends on its frequency in the population. This means that the success of a certain trait or behavior is influenced by how common or rare it is within the population. In frequency-dependent selection, the fitness of a phenotype may increase as it becomes more rare, or it may decrease as it becomes more common. This dynamic process can lead to the maintenance of genetic diversity within a population. **
