Movement and sensitivity
How does sensitivity signifty life?
Sensitivity signifies life by reflecting a deeper connection and responsiveness to the world, both internally and externally.
What is respiration?
Respiration is the process by which living organisms exchange gases, primarily oxygen and carbon dioxide, with their environment to produce energy.
Why do organisms need nutrients?
Organisms need nutrients for a multitude of life processes, including building and repairing tissues, supporting growth, and providing energy for various function.
What is excretion?
Excretion is the biological process by which living organisms eliminate metabolic waste products and other toxic substances from their bodies.
What is reproduction?
Reproduction is the biological process by which organisms create offspring, ensuring the continuation of their species.
How do animals that in a fixed position move?
Animals in a fixed position may move in place or change their body position without physically moving from one location to another.
Where do frogs breathe from?
Frogs can breathe through their skin, lungs, and the lining of their mouth. While they use gills in their larval stage, adult frogs primarily rely on their skin and lungs for breathing.
What is growth?
Growth is an increase in the size of an organism or part of an organism, usually as a result of an increase in the number of cells.
How does excretion signify life?
Excretion is a result of chemical reactions that generate energy and build necessary molecules. These reactions also produce waste, which must be removed for the organism to continue functioning. This shows that the organism is consuming nutrients, growing, and sustaining itself—all indicators of life.
Why is reproduction important?
Reproduction is crucial because it ensures the continuation of life. Without it, species would gradually disappear.
Why do organisms move?
Living things move for a variety of reasons related to their survival, reproduction, and interaction with their environment.
How do organisms breathe?
Land animals generally use lungs, while aquatic animals primarily use gills. Insects breathe through spiracles, and some animals, like amphibians, can even breathe through their skin.
Why do organisms grow?
Organisms grow and develop to increase in size and complexity, enabling them to perform more sophisticated functions and adapt to their environment.
What is the percentage of excreted(exhaled/breathed out) gases in the human body?
9.6%
How does reproduction signify life?
Reproduction is life!
It ensures the continuation of that species life.
True or false?
Movement refers to an organism's ability to respond to stimuli while sensitivity refers to a change in position or place.
False.
Why do organisms breathe?
Organisms respire because they need oxygen to survive. Oxygen helps organisms grow, reproduce, and convert food into energy.
Why is nutrition a characteristic of living things?
Nutrition is a fundamental characteristic of living things because it is the process by which they obtain the necessary substances (nutrients) to sustain life.
True or false?
Exhaled gases account for 9.6% of excreted substances.
True.
True or false?
Reproduced organisms are called babies.
False.
Reproduced organisms are called offspring.
What is the difference between movement and sensitivity?
Movement refers to a change in position or place, while sensitivity refers to an organism's ability to respond to stimuli, such as touch or light.
True or false?
1 breath of inhaled air contains 78% nitrogen, 21% oxygen, 0.04% carbon dioxide, and >1% other gases.
What is the difference between growth and nutrition?
Growth is the process of an organism increasing in size, while nutrition is the process by which organisms obtain and utilize nutrients for life processes.
Why do organisms excrete?
Organisms excrete to remove waste and maintain homeostasis, ensuring their survival and proper function.
How do organisms reproduce?
Organisms reproduce through asexual(single parent) or sexual(two parents) reproduction.
