Is there anything else I should do before I get my gerbils?
Gerbils will not die without a wheel! They will be fine without one, but gerbils do need exercise and you will find gerbils very much enjoy running on a wheel. The wheel you get is important. Do not buy a wire wheel as they can get their feet caught or tails caught and can break them off while running. A solid plastic "noiseless" wheel will hold up well for a while (not the flimsy plastic ones!). As for your question, as long as they have food, water, some things to chew and absolutely NO plastic anything in their cage, you should be set. Do make sure they are left alone for at least a day to de-stress. Once they become acclimated to their surroundings, you can start with letting them get to know you with your hand laying in their cage. Otherwise, if the cage is set up and you have the right bedding and items, you're all set to get your two little ones! (Just make sure it's only two and they are the same sex of course). =)
If the earth is rotating at a high speed and we jump up, why doesn't the earth move below us at high speed?
Since other answers have correctly mentioned the atmosphere and such, let's take it out of the equation for the sake of argument and see what happens.In terms of the difference in the helicopter's path vs. the ground, let's look at what happens during one whole day as the Earth rotates. Assuming the helicopter can perform an ideal, vertical-acceleration-only hover, then the surface of the Earth and the helicopter have the same tangential speed as the Earth turns, due to conservation of momentum. But, since the helicopter is now a few feet (~1 meter) above the ground, the path the helicopter takes to go around the Earth during one day is now slightly longer as compared to the surface itself. The added circumference of that trip all the way around the Earth for the helicopter turns out be just 2 times Pi times the height above the ground. It takes the Earth just under 24 hours to rotate once on its axis, so the helicopter would have to move at an additional horizontal speed of maybe 18 feet (~5.5 meters) per 24 hours, or something like 0.00014 miles per hour (~0.00022 km/h) to stay directly over the same spot on the ground. This is such a negligible difference in horizontal speed that you don't notice it in any practical system.A real helicopter would deviate horizontally by a speed that is orders of magnitude more than that when it takes off anyway. And, of course, helicopters fly in the atmosphere, which is coupled to the ground. It's also fair to say that wind speed dominates any effects from conservation of momentum, as it's orders of magnitude larger, even at high altitudes. So, real aircraft worry about the difference in wind speed and direction vs. the ground, rather than orbital mechanics.
What are the differences between herbs, shrubs, and trees?
Good question to ask !Herbs: The non-woody plants those have green and tender stems with few branches on are called herbs. They are usually short in height. Herbs have a variety of uses as providing medicines for diseases and some with spiritual touch. Herbs have aromatic properties that are usually used for delicious flavoring and garnishing food. As examples-BasilThymeLettuceShrubs: kind of bush and small to medium in size woody plants are called Shrubs. They are a bit taller than herbs and stems are not hard but thick. They could be distinguished from shrubbery by their multiple stems and shorter height. Some common shrubs are-Aloe veraRoseLemonTrees: Woody plants with elongated stems or trunks are called trees. trees have many multiple branches supported from the ground by the trunks. Typically, they are very tall in height and tend to be long-lived, even many species reaching several thousand years old. Trees serve us a lot of significant benefits in reducing soil erosion and moderating the atmosphere by absorbing carbon dioxide. They provide us shade and shelter, timber for construction since primitive era, fuel for cooking and heating, fruits, flowers, medicines and so on. Tress as examples-Mango treeBanyan treeCoconut tree
What are the five different ways seeds travel?
1. Wind- Some seeds are carried to a new place by the wind. 2. Water Dispersal- Fruits which float such as those of the water lily and the coconut palm are carried by water. 3. Animal Dispersal- Some seeds that are ingested by animals can be digested and later excreted out far away from the parent plant. Some seeds also have burs so they can attach themselves to animal fur only to later be dropped. 4. Explosion- Some plants have pods that explode when ripe and shoot out the seeds. 5. Fire- A number of species of pine have cones that only open after a fire. These are called serotinus. Jack pines have cones that are held closed by a resin sensitive to high temperatures. These cones will not open to release their seeds until a critical temperature is reached.
