The xylem is the structure of the plant that is responsible for transporting water from the ground up to the different parts of the plant. It is composed water, inorganic ions, and a number of organic chemicals.
<span>
Xylem tissue is found throughout the plant because not only does it transport water, but it also transports the nutrients that the plant needs for different processes. Aside from being responsible for the transportation of materials, the xylem is also used to replace water that was lost during photosynthesis and transpiration. </span>
Answer:
c. those genes that are located close to the site of the pophage insertion
Explanation:
In Specialized transduction, a restricted group of bacterial genes is passed to a different bacterium. Here, the prophage excises falsely from the chromosome such that the bacterial genes which are close to the site of the prophage insertion take part in the excised DNA.
Answer:
A
Explanation:
Nitrogen in the atmosphere can be transformed into a plant-usable form, a process called nitrogen fixation, by lightning. Each bolt of lightning carries electrical energy that is powerful enough to break the strong bonds of the nitrogen molecule in the atmosphere.
Answer:
Option B
Explanation:
Water soluble hormones associate with the G protein of cAMP. This G protein is intra-cellular i.e found inside the cell.
However in case of lipid derived hormones, the hormone has to diffuse through the cell across the plasma membrane to bind to DNA or the intra-cellular receptors.This regulates the gene transcription and induces protein production that affects the cell functioning for a long time.
Hence, option B is correct
