... get any Geraniums to grow in short and cold growing seasons, like in the Pacific Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just as good. Most people use them for crawling things to go over doorways and porches. Porches in the south were a very important place of the house. To have really colorful plants meant that it was a very happy place to be on warm summer night looking at all the different flowers. The really cool thing is the vibrant hangin ...

results when one or more of the cone cells fail to function properly. One of the visual pigments may be functioning abnormally, or be absent altogether.
There are several different types of , however, complete , or achromatopsia, is probably the simplest to understand. This is the rarest form of . This is when no colors can be seen at all. The color receptors are almost completely gone in this form, however, the white and black receptors remain intact. However, this condition is often misdiagnosed without proper testi ...

Cell Division
Number of Words: 395 / Number of Pages: 2
... microtubles attach to the kinetochores and overlap. In Metaphase, the chromosomes line up along the metaphase plate. The centromeres are all aligned and the sister chromatids straddle the metaphase plate. Anaphase beings when the sister chromatids are pulled away from each other. The chromosomess begin moving along the microtubles towards opposite ends of the cell, which is now in an oval shape. At telophase, the nonkinetochore microtubules elongate the cell even more, and daughter nuclei begin to form. Nuclear envelopes are reconstructed with fragments from the parent cell. Cytokinesis is norm ...

Big Bang
Number of Words: 1243 / Number of Pages: 5
... This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large scale, at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the model is more reasonable than the Steady State model. First, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves, the more shift it has. If the galaxy is moving closer, the sp ...

What Is Physics?
Number of Words: 2017 / Number of Pages: 8
... changes in ideas about the material world, but also, through technology based on laboratory discoveries, a transformation of society.”
Uncertainty in Measurements
Because the number of digits that are valid for any measurement is limited, the precision of all measuring devices is also limited. Every measurement is subject to uncertainty.
Causes of uncertainty:
1. temperature
2. magnetic fields
3. parallax
4. carelessness
Chapter 3:
General Principles of Temporal Displacement
In chapter 3, we learned that displacement is the change in position of an object. Because this interests me I decided ...

Dolphins
Number of Words: 878 / Number of Pages: 4
... oils have been found, so dolphins are not hunted for
this reason anymore. Dolphins can be caught in tuna nets by accident. Since
dolphins have to breath at the surface they drown in tuna nets. It is estimated
that 4.8 million dolphins were killed in tuna nets from 1959 to 1972. Under
pressure from animal rights activists tuna consumers will not accept tuna from
canners that do not protect dolphins. Animal rights activists also believe that
dolphins shouldn't be in captivity for use in aquatic shows.
Dolphins eat a lot of food in a day, usually about one third of their
body weight. A dolphin's die ...

metal concentrations.
Experimental
Soil preparation: Six surface soil samples were collected at the intersection of
Cold Spring Lane and the exit ramp of Interstate 83, in northwest Baltimore city.
These samples were collected at distances from the roadway of 0m, 2m, 4m, 6m,
10m, and 20m. These samples were dried in a convection oven at 110°C for over 24
hours then crushed. Aliquots of approximately one gram were weighed and then
extracted with 10.0 mL of 1M ammonium acetate. The extract was filtered with an
inline filter disc with a pore size of 5mm and then diluted to 1 ...

... the unified theory,
which is a theory summarizing the entire of the physical world; a theory that
would stand as a complete, consistent theory of the physical interactions that
would describe all possible observations. Our attempts at modeling physical
reality normally consists of two parts: a) A set of local laws that are obeyed
by the various physical quantities, formulated in terms of differential
equations, and b) Sets of boundary conditions that tell us the state of some
regions of the universe at a certain time and what effects propagate into it
subsequently from the rest of the universe. Pre ...

Acting To Save Mother Earth

... will decay naturally or that can be recycled. The idea is to prevent unrecyclable materials from even entering the home. For instance, 60 of the 190 pounds of plastic-especially styrofoam-each American uses a year are thrown out as soon as packages are opened. Be kind to your planet by buying eggs, fast food, and other products in cardboard instead of styrofoam cartons. Buy beverages in glass or aluminum containers instead of plastic ones. Buy in bulk to reduce the amount of packaging, you will save money too. Finally, when you can, buy products whose packing shows the "recycled" logo. Mater ...
