Science cannot prove or refute the existence of God or any other supernatural entity.
Absorption is when the root absorbs water from the soil and transfers it through the xylem. Transpiration is when the water leaves the leaf surface. The water reaches the leaves through xylem
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.
Hi , matter is made of single particles called atoms and is any substance that has either mass or volume.
Most fish need a minimum of 4 parts per million of dissolved oxygen in seawater to survive for long periods.
<h3>How can you mesure dissolved oxygen in water?</h3>
Dissolved oxygen (DO) is estimated utilizing a disintegrated oxygen meter or DO meter. The best strategy is to take the estimation in the field simultaneously every day, in light of the fact that DO fixations can shift all through a 24 hour time span.
Testing disintegrated oxygen (DO) in water is either estimated by means of substance examination, for example, a titrimetric technique, electroanalytical utilizing galvanic and polarographic tests, optical broke up oxygen, and colorimetric strategies.
In any case, present day procedures basically utilize electrochemical or optical sensor techniques.
The Winkler Method is a procedure used to quantify broke up oxygen in freshwater frameworks. Disintegrated oxygen is utilized as a mark of the wellbeing of a water body, where higher broke up oxygen fixations are corresponded with high efficiency and little contamination.
Disintegration of natural material,Bacterial oxidation of dead natural material consumes oxygen. This likewise makes sense of the relating expansion in supplement levels underneath the epipelagic zone.
