The sentence a Venus flytrap closes its leaves when its trigger hairs are stimulated is the best example of a living thing responding to its environment (option B).
<h3>What does characterize living organisms?</h3>
The main characteristics of living organisms refer to features shared by different life forms, which are essential to sustaining life, i.e. their metabolic activities in order to perpetuate across time.
One of the main characteristics that sustain life is the ability to respond to environmental stimuli. In this regard, it has been debated if this feature is the main characteristic that sustains life, but detractors of this idea state that it is not the main feature because viruses are able to respond to stimuli and they are not alive.
Therefore, with this data, we can see that the ability to respond to stimuli is one of the main features of living organisms.

They are both forms of active immunity.
<h3>What is active immunity?</h3>
When our own immune system defends us against a pathogen, this is known as active immunity. Our immune system develops active immunity when exposed to a potential disease-causing substance (i.e., pathogen). Active immunity is crucial since it not only "fights off" these pathogens but also lasts a very long period in the form of immunologic memory.
B and T lymphocytes with the ability to recognize a particular pathogen make up immunologic memory. These cells circulate at low levels in human bodies, but if they become "activated" by encountering the pathogen while traveling, they rapidly begin to multiply and send signals to other immune system components to do the same. There are two reasons memory cells are important. They first help our immune systems react swiftly. The immune response is prepared the moment the infection is contacted since they are secondly pathogen-specific.
I understand the question you are looking for is this:
What do "having the measles" and being vaccinated against the measles have in common?
- They are both forms of active immunity.
- They are both forms of neutral immunity.
- They are both forms of passive immunity.
- They are both forms of infection.
- They are both forms of immune deficiency.
