Capillary action is a combination of the adhesive and cohesive properties of water in which the water is able to move up a small tube against the pull of gravity. Therefore, the uptake of food and water is due to capillary action.
Change in climate has nothing to do with adhesion and cohesion in water. Some insects can walk on water due to surface tension, which is due to cohesion. However, there is no movement upward through a tube with surface tension, and so it is not an example of capillary action.
Hope this helps! :)
In the early stages the embryos of four different species will look the same .For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth. That what makes them different.
Answer:
Porque puede decirnos si su información incorrecta o información correcta
Answer:
You can use the quantitative Reverse Transcription Polymerase Chain Reaction PCR (RT-qPCR) method in order to analyze the Oct4 mRNA level.
Explanation:
RT-PCR is the gold standard technique to analyze the expression levels of one particular messenger RNA (mRNA) molecule. In this technique, the total RNA is firstly extracted and transcribed into complementary DNA (cDNA). Subsequently, the gene sequence of interest is then amplified in a standard PCR technique that uses as control one or more genes in order to measure the relative expression levels of the target mRNA, in this case, for example, the Oct4 mRNA.
