<span>The pros of having this rock plug is that the plug is protective and makes it so that Vesuvius is not likely to erupt again and the magma below has cooled and is harmless. The cons are that if there is another eruption, it will be deadly and create an avalanche of gas, rocks, and hot ash.</span>
The root nodules of leguminous plants houses nitrogen-fixing bacteria called Rhizobia. Rhizobia has a symbiotic relationship with leguminous plants that allows both to benefit from each other.
By binding to hydrogen, the Rhizobia bacterium is able to convert or fix nitrogen gas into ammonia , a form that the plant can use. Likewise, the legume plant provides the rhizobia bacterium with carbohydrate which the rhizobia depends on for energy. It is important to note that the carbohydrate sent to the nodules for the rhizobia is also what is used as a source of hydrogen to help the bacterium convert nitrogen to ammonia.
Answer:
<em>It is the outermost covering of a cell that separates the contents of the cell from its external environment. </em>
<em />
<em>It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.</em>
<em />
<em>Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.</em>
<em />
<em>Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.</em>

<span>through the urethra to the postrate
Sperm at that point goes through the deferent channel through up the spermatic rope into the pelvic depression, over the urethra to the prostate . Here, the vas deferens joins with the fundamental vesicle to shape the ejaculatory channel, which goes through the prostate and exhausts into the urethra. At the point when discharge happens, muscle action impel the sperm forward.</span>
