Answer:
Publication bias is the phenomenon where positive trials are more likely to get published than negative ones, and it can happen for a huge number of reasons, sinister and otherwise. Major academic journals aren't falling over themselves to publish studies about new drugs that don't work.
One example can be the needle shaped leaves.
In desert areas, there are not much water sources. So basically, any drop of water is precious. To help prevent water loss of plants, for example cactus has very thin leaves that are needle shaped. Or some even don't have any leaves. This can reduce the surface area of leaves and thus reduce the water evaporating to the outer environment.
Another example also shown on cactus is that they have very thick waxy cuticle. It can also prevent water from evaporating from the stem. So that's why you see the stem is very shinny.
Abiotic things are nonliving and biotic things are living.
Explanation:
A conductivity cell is a device that is comprised of electrodes that sense the electrical conductivity of a substance, such as water. ... To get a conductivity reading, the cell constant and the conductance of the material have to be multiplied.
carbon dioxide + water —> glucose + oxygen + water.
6CO2 + 6H2O —> C6H12O6 + 6O2.
