Earth's orbit is the path in which the Earth travels around the Sun. The average distance between the Earth and the Sun is 149.60 million kilometers (92.96 million miles) and a complete orbit occurs every 365.256 days (1 sidereal year), during which time Earth travels 940 million kilometers (584 million miles

Answer: The rays of the summer sun, high in the sky, arrive at a steep angle and heat the land much more than those of the winter sun, which hit at a shallow angle. Although the length of the day is an important factor in explaining why summers are hot and winter cold, the angle of sunlight is probably more important.

<span>3)Add iodine (1 min)
4)acid/alcohol wash (1 min)
5)Flood with safranine (1min)
6)Air dry and examine.
These times are for clinical microbiology and experimental methods employ optimal and more precise times (but overall its pretty close).
Down side of this method is that you must smear bacteria onto the slide and fix it by heating the underside of the slide with a bunsen burner. if they are pink then you have gram negative (Gram's stain didnt stick) if its purple then its gram positive(Gram's stain did stick) This is due to the peptidoglycan layers. Gram negative bacteria have only a thin layer of peptidoglycan as part of the cell membrane/wall where Gram positive have a very think peptidoglycan layer.</span>Source(s):<span>Medical Microbiology</span>
