Biology

nlexa [21]3 years ago

Elephants have pointy tail because they need it to become more streamlined and for their aerodynamics. Being streamlined and having aerodynamics helps them to have a little resistance to air and water flow. It also helps them to increase speed and for ease of movement.

Like plants, human beings have similarities and differences. God gave us talents which He wants us to use. What can you do best?
asambeis [7]
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P

Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.

Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.

One watershed can encompass another watershed.<br> Select one:<br> True<br> False
beks73 [17]

The right answer is True.

A watershed is the expanse of territory drained by the waters of rivers and lakes, which in turn converge to a common outlet. Groundwater is flowing into the watershed, although the boundaries may not exactly coincide with surface water. Smaller flow areas that feed subwatersheds can be called catchment basins or drains. Watersheds can flow into river basins that may encompass larger areas.

Known watersheds are separated from one another by ridge lines, also known as watersheds. These are designed to delineate the watershed.

Watersheds are nested networks, the smaller ones nesting in larger ones. Streams that form the watershed can be organized according to a ranking framework. For example, the upper streams at the highest elevation of the watershed are first class streams.

When two first-class rivers meet, they form a second-rate stream. When two second-rate rivers meet, they form a third-class watercourse. A stream joined by another lower ranking stream retains its rank. For example, a third-class watercourse joined by a first or second-rate watercourse remains a third-rate watercourse.
