Answer:
Fusarium oxysporum is a fungus which obstructes xylematic ducts in the tomato plant and causes necrosis in the ploem of the plant.
Explanation:
The xylem in a plant is made up of differentiated cells, this cell system performs apoptosis so that the dead cells form a structure called the xylematic ducts. And so it gives way to the creation of a system through which the absorption of water from the soil will be carried out until it reaches the leaves of the plant. What fusarium does when colonizing the xylematic ducts, is to cover them, obstruct them and in this way is that this fungus prevents the absorption of water for the leaves of the plant.
The ploem is another structure in the plant. The phloem has the function of transporting the nutrients made by photosynthesis to those parts of the plant that cannot perform this process that are usually located in the basal or underground part. this will generate that there is no adequate passage of nutrients for the whole plant and its subsequent wilting.
Answer:
Population is growing rapidly, far outpacing the ability of our planet to support it, given current practices.

Answer:
Sticky ends are more useful in molecular cloning because they ensure that the human DNA fragment is inserted into the plasmid in the right direction. The ligation process, or fusing of DNA fragments, requires less DNA when the DNA has sticky ends.
