Cohesion: When water molecules stick to one another through cohesion, they fill the column in the xylem and act as a huge single molecule of water (like water in a straw). Capillary action: Capillary action is the movement of a liquid across the surface of a solid caused by adhesion between the two.

Answer:
-if I'm not wrong the technique is used to produce the bacteria cell is DNA cloning because after a ligation, the next step is to transfer the DNA into bacteria in a process called transformation.
-The organic compounds scientist used to cut DNA is enzymes.
-the possible result would be the transformations made and selection of the bacteria.
The core of a star must react a temperature of 10,000,000 degree Celsius for hydrogen fusion to begin
Explanation:
A star formed from a rotating cloud which is made up with completely with helium and hydrogen. The gravitational force pulls the cloud behind to collapse inward and due to this it shrinks and later it spins more and more quickly with the outer parts.
When the core and inner part become a rough spherical clump then it becomes disk. The star life cycles follow the patterns which is based on mostly on their initial mass.
