I found it here: http://www.physorg.com/news128167633.html It's dependent on size. There is a minimal size requirement to allow for all of the cellular functions. This was a stupid question in the HRW science book.
Yes, sea sponges are alive. They are multicellular animals that live in marine environments. They obtain nutrients by filtering and extracting particles from the water.
An object is considered alive if it exhibits characteristics such as growth, reproduction, response to stimuli, and metabolism. These traits differentiate living organisms from inanimate objects.
Nanoparticles are not alive, as they lack the ability to carry out biological functions such as growth, reproduction, and response to stimuli. They are inanimate particles that are designed and engineered for specific applications in fields such as medicine, electronics, and materials science.
Two characteristics that can help determine if a specimen is alive under a microscope are movement and cellular structure. If the specimen shows any signs of movement, such as flagella or cilia, it is likely alive. Additionally, if the specimen displays organized cellular structures like organelles or a cell membrane, it is most likely a living organism.
To determine if something is alive, look for characteristics like growth, reproduction, response to stimuli, metabolism, and organization. Living organisms exhibit signs of life such as movement, breathing, consuming food, and showing signs of growth or development. If an organism displays these characteristics, it is likely alive.
Microscopic particles are so small and hard to see with the human eye that is they are alive their movement would be small making it hard to determine whether they're alive or not.
If it's alive, not microscopic, and not plant matter, it's an animal.
It is difficult to determine if a duck embryo is alive based solely on a dark spot inside the egg. To confirm viability, it is best to consult with a veterinarian or experienced individual who can perform egg candling to observe the development of the embryo and determine its status.
An amoeba is a living organism. It is a single-celled microscopic organism that carries out essential life processes such as feeding, moving, and reproduction.
The first person alive would be difficult to determine as there is no definitive answer. Some believe it to be Adam and Eve from religious texts, while others may refer to a scientific perspective which would point to an early human ancestor.
No, It's a lung disease you get from breathing in microscopic Volcano dust. So it's not alive.
It can be difficult to tell if a fish is sleeping or dying. Look for signs of movement or breathing to determine if the fish is still alive. If you are concerned, consult a veterinarian or a fish expert for advice.
No. Nothing in the sun is alive.
We do not yet know what "matter" is and what "alive" means, so answering such a questions is rather difficult.

It's difficult to determine the exact number of psychopaths, as it varies depending on definitions and diagnostic criteria. Estimates suggest that approximately 1% of the general population may meet the criteria for psychopathy.
Because it is caused by a virus, H1N1 is not actually alive. Viruses are called "active" or "inactive" usually, because they are different than bacteria and other microbes that are actually living microscopic organisms.
