Well they eat and avoid predators.
Eat or be eaten.
Sorry the answer is so simple, just they DO need to eat.
Functional Requisites are basic functions that must be carried out for societies to survive and thrive.
If they don't have brains then they must not be alive so they dont have to sleep!!! What a stupid question!
A function calculates a value based on some other values (or several values), using some rule. The only rule that functions must follow is that the value calculated for the function must be uniquely defined.
All animals try to protect themselves in one way or another. It is part of being alive.
no hitting animals (of course), if animals are left in cars windows must be open enough for air to come in, must be fed properly and NOT left to fend for themselves. no endangered pets without licenses.
The three characteristics that show a cell is alive are the ability to reproduce, to grow and develop, and to respond to its environment. Cells must maintain these functions to stay alive and function properly.
yes it must be alive
It must obtain biological energy to stay alive.
Humans are considered animals. Animals are made of flesh and are alive due to chemical reactions. Are humans any different? The few things that set us aside is the ability to talk, etc.
ALL animals must eat to remain alive. If a bat (or any other animal) does not eat, it will die of starvation.
A single-celled organism must perform several essential functions to stay alive, including metabolism to convert nutrients into energy, reproduction to ensure its survival through offspring, and response to environmental stimuli to adapt to changes. Additionally, it must maintain homeostasis, regulating internal conditions like pH and temperature, and carry out cellular processes such as respiration and waste removal to eliminate toxic byproducts. These functions collectively enable the organism to thrive in its environment.
An organism considered dead can no longer perform life functions and does not respond to stimuli. In contrast, a living organism actively maintains homeostasis and responds to its environment to sustain life processes. The concept of an organism being "dead and alive" simultaneously does not align with biological definitions.
