why does the panama canal have locks

] Why does the have locks? What would happen if they were taken away and the Atlantic and Pacific oceans flowed into each other? The isthmus of land between Port Sad and Suez is so low-lying that it was possible to cut a canal across it without the need for locks, so the Mediterranean and Red seas are directly linked. The Panama canal, on the other hand, rises to a maximum of 26m above sea level, at Lake Gatun, an artificial freshwater lake formed by damming the Rio Chagres. Ships entering the canal from the Pacific are first raised 16. 5m by the two-stage Miraflores lock up to the (again artificial) Miraflores lake, and then to the 26m level at the Pedro Miguel lock. They follow the flooded Rio Chagres for a while, cross Lake Gatun and descend via the three-stage Gatun lock to the

why does my knee hurt when i bend it

Being active is one of the best things you can do for your joints and the rest of your body. But injuries can happen, and they often involve the knees. Some of the most common problems are sprained ligaments, meniscus tears, tendinitis, and runner's knee. If you have an old knee injury that wasnБt properly treated, it may flare up now and then or hurt all the time. Several other things can also cause knee pain, such as: Bursitis: A bursa is a sac that holds a small amount of fluid thatБs under the skin above your joint. It helps prevent friction when the joint moves. Overuse, falls, or repeated bending and kneeling can irritate the bursa on top of your kneecap. That leads to pain and swelling. Doctors call this prepatellar bursitis. You may also hear it called ''preacher's knee. "

why does my dog keep sneezing and coughing

Foreign bodies A "foreign body" in your dog's nose means there's something in there that shouldn't be. For example, if your furry family member likes to dig in the dirt or obsessively sniffs the ground, chances are she'll wind up with some soil, grass or the occasional bug up her nose. This will cause her to sneeze to expel the foreign material. Hunting and sporting dogs who spend a lot of time outdoors running at full speed through natural settings can also wind up with odd things (e. g. , twigs or sticks) up their nose. Sneezing will ensue as the dog's body tries to expel the foreign invader. Sometimes, however, medical intervention is required. Suffice it to say, the list of weird stuff veterinarians have removed from doggy noses is a long one! Signs of the presence of a foreign object

 why does my cat not use her litter box

why does my cat not use her litter box

Observe the cat and notice if he is straining to go and/or crying out. He may claw out a space in a potted plant, choosing clean dirt over a soiled litter box. Or he may squat on your carpet or floor because he associates the sensation of digging in litter with uncomfortable elimination. If you confine him to a closed room with a clean litter box and he ignores it, he may have no control over his actions. This signals that illness, not behavior, is the culprit. The cat is in pain, and your vet needs to determine why. A thorough checkup will reveal whether Kitty has a urinary tract infection, inflammatory bowel disease, diabetes, arthritis, kidney, liver or thyroid malfunction or other illnesses that may affect his litter box habits. If illness, minor or serious, is the cause, medication

why does the 5 2 diet work

The body is a temple. In January, for the most part, it is a rather large and overfed temple. This year, under the pressure of constant lifestyle and dietary advice, I decided on a remedy: the intermittent fasting diet. The regime, which instructs dieters to feast for five days a week and fast for the remaining two, originally took the States by storm in 2013. It has gradually crept over the pond, with numerous bestselling books ( The Fast Diet: Lose Weight, Stay Healthy, Live Longer and ) and celebrity adherents ( ). In fact, it s not just contemporary celebs who are singing its praises: Plato once said I fast for greater physical and mental efficiency ; Aristotle was said to be a faster, too. Martin Luther announced: It is right to fast frequently in order to subdue and control the

 why does my cat sleep with her eyes open

why does my cat sleep with her eyes open

My cat sleeps with his eyes open. It scares me. Why does he do it? Eyes-open unconsciousness reminds us of death, so I understand why it scares you. Fortunately, you donвt need to worry about him. Some pets do it, as do some people, and the behavior seems to happen more frequently in older age. Your cat could get dry eyes if he frequently sleeps that way; your vet can prescribe drops if needed. Keep this in mind about your open-eyed cat: Sleepy as he is, with those eyes open heвs probably more prepared to spring into action at a momentвs notice than his closed-eyed counterparts. ...

why does the world map look the way it does

WHAT IS WRONG WITH THE MERCATOR MAP? As a result, shapes of world maps have typically been diverse, ranging from hearts to cones. But the diversity gradually faded away with one model, invented by Gerardus Mercator, surpassing the others. The familiar 'Mercator' projection gives the right shapes of land masses, but at the cost of distorting their sizes in favour of the wealthy lands to the north. For instance, in the Mercator projection, north America looks at least as big, if not slightly larger, than Africa. And Greenland also looks of comparable size. But in reality Africa is larger than both. In fact, you can fit north America into Africa and still have space for India, Argentina, Tunisia and some left over, notes Mr Wan. Greenland, meanwhile, is 1/14th the size of the continent as

why does my dog try to bite my hands

Your pooch also could be chewing on your hand as a reaction to stress in his life. Perhaps he s scared about the loud and persistent sound of your neighbor mowing his lawn. Perhaps he s stressed out because he feels isolated and lonely, or maybe because he doesn t receive enough regular physical fitness. Since this type of chewing can sometimes trigger fierce behavioral patterns in canines, it s crucial to be cautious about it. Look for problematic body language hints of these behaviors in your pet, such as rigid posture and visible teeth. In many cases, these bites feel markedly different than playful chewing -- significantly sharper and faster. If you think your doggie s hand chewing is in any way related to these types of patterns, talk to an expert in pet behaviors. Do not under any
