form at opposite "poles" of the cell. Many consider prophase (versus interphase) to be the first true step of the mitotic process. What are the changes that occur in a cell during prophase? Chromatin fibers become coiled into chromosomes with each chromosome having two chromatids joined at a centromere. In the cytoplasm‚ the mitotic spindle‚ consisting of microtubules and other proteins‚ forms between the two pairs of centrioles and centrosomes as they migrate to opposite poles of the cell.

As people on the ground use longitude and latitude to find things on earth‚ scientists and astronomers use right ascension and declination to find things in the sky. 2. The North Pole is north 90 degrees latitude and the South Pole is south 90 degrees latitude. There is no longitude for either the south or North Pole because neither one can be given a value. 7. Tidal bulges cause a normal average of two low and high tides within a day but this is not always the case. It mainly depends on your

Sun Dance. The buffalo was incorporated in many ways in the Sun Dance. The Cheyenne held a principle that "all essential sacred items in the sun dance (be) related to the buffalo." (Atwood) The Lakota would place a dried buffalo penis against the sun-pole to give virility to the dancers. This "reinforces the symbolic meaning of the ceremony as a celebration of the generative power of the sun." (Atwood) The buffalo skull is used as an alter during the Sun Dance. Offerings are presented to the skull‚

advocate safety. An instance of safety being rewarded in the game comes in pole whacking. Pole whacking is a crucial part of ski safety‚ because if you think about it‚ when you come up to a cliff and there is a bunch of fresh snow blocking your view of what you’re about to get yourself into‚ you really need to whack your pole into that snow to clear a line of sight and also get a feel for the snow that you are about to ski. Pole whacking is something that is universally embraced by both skiers and snowboarders

different types of tents. The frame can consist of rigid longitudinal poles which transfer loads similar to a column‚ or it can consist of flexible rods that transfer loads similar to an arch. 3.) An anchorage system – The anchorage system of a tent usually consists of tabs (attached to the membrane) that are attached by hooks to the stakes. The stakes are then anchored into the ground. Some tents use ropes that are attached to the poles which are in turn anchored into the ground using stakes. Some

Q: DESCRIBE THE 3 METHODS OF LEVELING AN AIRCRAFT Answer taken from CAAIPS PT 10 Levelling For some purposes‚ such as rigging or weighing‚ an aircraft must be leveled laterally and longitudinally and a number of different methods may be employed. 1 Spirit Level Many aircraft are levelled by use of a spirit level‚ which is placed at jigged positions on the airframe structure. On light aircraft the longitudinally level position is generally obtained by placing the spirit level on two pegs or on the

providing more pulses at each revolution. The generated voltage depends upon the number of poles and armature winding turns. It has armature with iron core and air gap which is uniform the vicinity of the center of the pole and which becomes larger as the pole tips are approached. This construction gives a uniform flux distribution under the main parts of the pole face with a reduction in the flux at pole tips. To produce an emf the conductor must cut the magnetic lines of force. The single coil

I Early Prophase I D.N.A coils tightly and individual chromosomes become visible as single structures Homologous chromosomes become associated in synapsis. Each pair of chromosome is called a bivalent. Centrioles divide and move to the opposite poles of the cell‚ and spindles start to form Late Prophase I The bivalents duplicate to form tetrads (four-chromatid groups).The nuclear membrane disintegrates. Chromosomes join at points called chiasmata where crossing over takes place. Metaphase
