12. [could be both]
In order to see if something is Biotic or Abiotic, think about whether it’s alive or not.
Dissolve oxygen is just the oxygen levels in the ocean, it’s not really a living thing. While it does effect the environment, it’s abiotic because it isn’t living. Fish, however, are are biotic because they’re alive.
If you’re ever confused, just think about the basic things all living things have, which is cells, and apply it to the question. Does changing weather have cells? Nope. do trees have cells? Yep!
Also, for the Fertile soil, I said it could be both because of what’s in the soil. Fertile soil has biotic factors in it, like dead animal stuff and dead plant stuff. (Anything that was once living, even if it’s dead, is still considered a biotic by the way). I think your best bet would be to put biotic, but I might be wrong
But yeah, in summary, Biotic means living, Abiotic means non living, and in order to see which is which, ask yourself if whatever you’re questioning has cells. Good luck
Answer:
A bee hive in a hollow tree
Explanation:
Commensalism is a type of biological interaction in which one species is neither harmed nor benefited but the other organism is benefited. In the given question, the bees live in a colony with making a hive attached to the substratum.
The bees which make hives in the hollow space of the tree will be considered as a case of the commensalism as only this is the case in which both the things are living (biotic) and the bees can take nutrition from the flowers of the tree, the well protected shelter to make a hive and other benefits but the tree is neither benefited nor harmed.
Thus, the selected option is correct.
The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.
Answer:
Conduction transfers
Explanation:
Conduction transfers heat energy in solids. The moving particles of a warm soild material can increase the heat energy of the particles in a cooler solid material by transferring it directly from one particle to the next. Since particles are closer together, solids conduct heat better than liquids or gases.
Because by practicing, they control there breathe and also increase the volume of the lungs ! so , it is just practice, we can also have that type of lung by regular efforts !
