3. How does a pitcher plant catch insects? |
| Answer» <p>Pitcher plant is an insectivorous plant that derives nitrogenous compounds by trapping and consuming insects. The leaf of a pitcher plant is modified to form a pitcher-like structure. When an insect sits on the pitcher, the lid of the pitcher gets closed and the insect gets trapped inside. The insect is then digested by the enzymes secreted by the plant. In this manner, pitcher plants fulfil their requirement of nitrogen by feeding on insects. that's because they grow in the that part of the area where there is no nitrogen present .they eat insects because they are rich in nitrogen. so the pitcher plant eats insects. you can say Pitcher plant is a trapping plant or insect trapping eating plant. if you like my answer please give me like and comment to my answer.</p> | |

s) How the hen baby w |
| Answer» <p>Weeks 1-2</p><p>Your little ones are freshly hatched newborns and are experiencing their first weeks in the big wide world! The baby chickens will be tiny little things (but you’ll be surprised how fast they’ll grow right before your very eyes!)</p><p>Straight after the hatch</p><p>After spending 24-48 hours in the incubator post-hatch, the baby chickens will be moved to the pre-warmed brooder – where they will stay until they have grown and are strong enough to no longer require a heat lamp.</p><p>Eating and drinking</p><p>During this first two weeks, the baby chickens will be very fragile and unaware of how to do…well…anything really! That means you as a ‘mother hen’ will need to teach them how to perform the necessities- eat and drink. This can be done by gently dipping their heads into the waterers and feeders. If you have some particular clever chicks on your hands, they might get the idea straight away, other times it may take a little more patience and persistence – but, we promise it won’t be long before the baby chickens will be able to eat and drink whenever they need to by themselves.</p><p>Starting the growing process</p><p>For these first two weeks, the baby chickens will be growing their muscles and building up their strength! At first, their legs are fragile and weak, which is why the brooder needs to be lined with strips of paper towel. This gives the baby chickens a sure footing and stable flooring for them to build up their strength, with only a few slips and spills.</p><p>Encourage handling</p><p>Want to bring up chickens that love having cuddles with your own children? If you handle your baby chickens regularly, they will become accustomed to being petted and cuddled, and won’t stress or fret as adults when you try and pick them up. In the first 7 days, it’s best to leave them be as they are such fragile little creatures – but after that, try softly picking them up and lightly stroking them for small periods of time to get the ball rolling. Before you know it, they’ll be coming to you for some snugs!</p><p>Weeks 2-4So we’re two weeks in and you’ll be amazed at how much the baby chickens have grown! They’ll virtually be double the size they were when they came out of the egg, if not larger. These two weeks are often the ‘teenage awkward’ stage – where they aren’t quite babies anymore, but aren’t fully grown either! Their feathers are a little patchy, and they’re starting to grow taller, but aren’t fluffy! They’re definitely still cute- in an oddball kind of way.</p><p>Getting stronger everyday</p><p>By now, their legs will be strong enough to walk on shredded paper instead of strips, so you can replace the brooder bedding with finer shreds. You can also start giving them little bits of outside-the-brooder time (not too much, they still need the comforts of the heat lamp for a little while longer!). Don’t be surprised if they stay still in fear at first – the big wide world is quite confronting for a baby chicken! Remember to keep handling your little ones so they don’t mind the odd pet or cuddle from their human owners.</p><p>Self-sufficient</p><p>By now, the baby chickens should be eating and drinking as they please, without any encouragement from their ‘mother hen’. Just make sure that there’s starter feed and fresh water available to them in the brooder.</p><p>Weeks 4-6</p><p>My how the time has flown!</p><p>By now you will barely be able to recognise your little baby chicks, as they have virtually tripled in size! By week 6 they’ll have a full body of feathers and look like a small version of an adult (they’ve still got a little more growing to do before they’re full sized!).</p><p>New digs</p><p>You’ll also notice that they’re looking awfully squishy in that brooder there! Week 6 is around the time you should move your little ones into their second home – a chicken coop fit for a fully grown flock! If the temperature is fairly average, then they’ll be able to last in the natural elements – plus their coop will offer them lots of ventilation which will help them adjust to their new lodgings. It’s always a good idea to get the coop before it’s time to move the baby chickens out – otherwise they’ll become so cramped in the brooder that they’ll start to stress! The size of your coop depends on how many chickens you have. If you were looking to have eight or more chickens, why not check out our Penthouse or Mansion range.</p><p>Weeks 6-8</p><p>By now your beautiful baby chickens have become young adults – or ‘pullets’ as the young ladies are now known! It will only be a few more weeks before your little baby chickens start laying their own eggs for your breakfast! Oh, how wonderful the experience is of raising baby chickens to be a fully grown flock!</p> | |

Mention three damaging eftects alallu iCUllustrate an example to show that high speed wind reduces air pressure. |
| Answer» <p>A cyclone has high speed winds followed by low pressure air region blowing.Thus during a cyclone, the high speed windsover the roof tops, nothing much happens. But whenthe low pressure region comes above the loose roof top, due to pressure difference between inside and outside the roof, the roof top is blown away in air.</p><p>Tie two blown balloons to a rod so that there is some gap of 20 cm between the inner surfaces of the balloons. Now place your mouth in the center of the balloons and blow air between them. Initially the balloons go up horizontally in air and get separated a little more. But when you stop blowing, the region develops low pressure, ascompared to the air on the other side of balloons. So the balloons come closer to about 10 cm or 15 cm.</p><p>Take a light paper piece, or thermocol piece or a small feather. keep it in a plastic bottle (1 or 2 litre mineral water bottle. Keep the bottle horizontal with its mouth towards your mouth. Start withthe paper piece or feather at the mouth of the bottle. Then blow air slowly and steadily through the bottle. It first goes to the bottom of the bottle and then after u stop blowing, it comes back to the mouth again. It comes back because at the mouth there is a low pressure region. So air from the bottom of the bottle rushes towards the mouth.</p> | |
