As a result of the creek covering such a large area, Bulimba Creek is a very important part of Brisbane’s ecosystem and society. Although Bulimba Creek is a part of…

Leaf Day There are those teachers who just “get” you. There are more who don’t, but it’s the ones who do that can make all the difference (or so I used to think). My child-hating first-grade teacher Ms. Gordon didn’t “get” me. So when I forget all about Leaf Day it’s dreadful. And trying to finish the assignment by skipping class only increases my negligence. However, When Ms. Gordon shows a little leniency and decides not to fail me it has a lasting impact on me and significantly changes my…

Though, autumn and spring are similar seasons, they have many drastic differences such as climate, holidays, and changes in appearance. Spring is the…

Two Leaves, One Gone You know, I tried. I really did. As I sit here, a hole in my heart, (literally and figuratively) I wonder what I did any of this for, why this came to be. Sorry, my name’s King. I get distracted easily. I am your average but not average high schooler. Not to brag, but I’m kind of a genius. I’m a senior at 16, and had a fairly nice life. I had my loving mother, but my father had died two months ago to cancer, and it was hard carrying on. My little sister in particular, had…

P. putida and P. fluorescens isolates were cultured in 250 ml Laurea Broth (LB) medium at 30±1 ºC for 36 h in an incubator shaker at 150 rpm. The culture was then poured into 50 ml falcon tubes and centrifuged for 10 min. at 6000 ×g at 4 ºC. The pellet was washed thrice in 15 ml distilled water and centrifuged. Then it was dissolved in distilled water and the optical density (O.D) of the culture was set at position-1 at 600 nm=107–108 colony forming units (CFU) ml-1 for inoculation (Bhuvaneswari…

significant difference in stomatal densities between young and old leaves or no. The stomatal density of young and old leaves has not significantly different densities. The age of the leaf does not аffect and do not correlate with stomatal density. Because, when the leaf is a baby leaf it makes all the stomata and as leaf growth it just pulls apart from each other. Stomata has an essential rоle in all plаnts. Stomata helps to maintain balance between water and gas exchanges. The word stomatа…

early leaf’s a flower; But only so an hour. Then leaf subsides to leaf. So Eden sank to grief, So dawn goes down to day. Nothing gold can stay.’’” Some readers may brush it off thinking that it was an unimportant and random piece of the novel, but this is not true. The Outsiders and the poem, “Nothing Gold Can Stay” by Robert Frost are alike in many ways. One way that the book relates to the poem like this is with the line “Then leaf subsides to leaf.” This line means that leaves give way to…

Moreover, this particular species of tree is very popular because it grows most commonly around burn sites. After a natural disaster the Quaking aspen is usually one of the first trees to take root. The Quaking aspen is well known here because of this, however the common person may find it hard to identify when an aspen tree is not healthy. Sooty bark canker (encoelia pruinosa) is a canker is…
