flowers + panadole

well hello and hi again.
i am back.
cut to the point. today, this post is about panadole and flowers.

if you are still able to remember about ms deepa talking about the flowers and what happens when panadole is dropped into it? yeah this is what this post is about.

my mother bought some lilies a few days ago (weeks would be better) and instead of putting panadole, she placed fever medicine and i do not think it really worked as the petals turned brown/black even before they even open. so i guess it does not really work that well.

my mother guessed that the lilies are from a different breed and thus, the result is like that.

DONT KNOW.

I guess there is something wrong with my computer and i cannot upload the pictures i took but i took this form the internet it is something like this but imagine it brown.sorry.

the flowers are more like the bottem left but brown.

respiration

respiration involves a chemical reaction.
the process of respiration is

glucose + oxygen -> carbon dioxide + energy + water

glucose -> from food
oxygen -> inhale
carbon dioxide + energy + water -> exhale

respiration happens in the mitochondrion
(my-to-con-dria)

animals that contains chloroplast.

it seems that slugs have chloroplast in their body. they do not make their own food but they still eat. as to how they get the chloroplast in their body, the slugs feed on algea which chloroplast are derived. sea slugs are also included.

are viruses / bacteria cells?

this post is on bacteria. the other one was on viruses.

bacteria on the other hand is a single-celled organism.

a group of bacteria contains chlorophyll and use the process of photosynthesis to make their own food.
some bacteria are aerobic, meaning that they require oxygen in order to
survive.
Other bacteria are anaerobes, meaning that they do not require oxygen to survive.

Bacteria that are parasites live inside man, animals, and some plants causing diseases.
Symptoms for disease caused by the toxins that bacteria produce inside the cells.

Bacteria is moved by air and water currents, and on any surface such as clothing, hands, or any object.
They move themselves by using thin hair-like structures called flagella or by wriggling if they do not have a flagella.

There are three ways to identify bacteria; gram stain, respiration, and shape.
Most bacteria reproduce asexually. That means that new cells are formed during single cell division. Some bacteria can only reproduce sexually, with a male and female bacteria.

Bacteria are decomposers, they break down the chemical elements inside other living or dead organisms.

bacteria growth. cannot find something else other than bacteria growth.

are bacteria / viruses cells?

the answer is...
nope

Because viruses are non-living things and so they do not need for food like living things. They are just light particles that float around the air and they cannot be seen by the naked eye and they can be passed on to other organism if touched. They attack healthy cells in living things. Viruses do not have an organized cell structure.They do not have characteristics of living things and thus, cannot metabolize food.

To metabolize means to change food energy into chemical energy that the body can use.

The virus injects its own DNA structure into healthy cells where new virus cells grow.

note that i am talking about viruses instead of bacteria.

Viruses that are mature have characteristics that help to identify them.

Viruses can not reproduce by themselves like bacteria or cells. They must attach themselves to the cell membrane of animals / cell wall of plants and inject a part of their DNA into the cells of the host organism.They do this by using a hollow tube structure to puncture the cell wall/membrane and pass its DNA into the cell. New virus cells are incubated inside the invaded cell. Once the virus DNA reproduces itself inside the cell, it uses the natural process of osmosis to leave the cell. These new virus cells would then attach and infect other healthy cells

just another video showing how viruses spread but this is the
Influenza Type-A Virus

biology

ok, i should have introduced biology on the first day of biology class.
anyway, i don't think anyone would be reading because we have a project on hand and the 10% is not this but
the project but i just post it for the fun of it but that would officially start on the next post later on in the day which is later.

coke and mentos

sorry for the late post on my group's coke and mentos.haven't been using computer recently.

my group members: sarah,janelle,rachel, me

hypothesis:the more the amount of mentos, the higher the height of the mentos that shoots out.

result: GREAT!!!

things that went wrong:the mentos were stuck in the bottle so it won't come out and the disered ampunt of mentos that we wanted to put in was unfortunately changed.

such a pity for this picture below.could have taken the full photo but it all happened too fast for me to capture it. but i still love it.

this is the last picture of the whole collection.

actually, i took a lot more but it is redundant to show anyway so these are the few good pictures.hope you all like it and sorry for the late posting of it.
XD

frankly speaking, i don't know which of the follow is my group's photo so to my fellow group mates, sorry.if you want our group's photo, go see janelle's blog.(<-click there)

DIET coke and mentos only.

wow!!!!!!!!!!
this video is so cool!
it seems as if they were holding a fountain parade. XD
but they tried the experiment a lot of times in order to achieve the result.
sorry if it did not show you why or how it actually works.
as in how the mentos reacts with the coke.
if you want to see, go rachel's blog.
it is showcased there.

paper chromatography

this is another video by me today.

This is the first one. The bottom one is the rectangle chromatography paper. Some parts of it is fast-forward so it may look very wierd. And the liquid that is poured into the tube is not water but ethonal . they did draw the line but they used permarnent marker instead of pencil and thus, don't need to add the ink. the colours that is shown is unlike ours which is like 1 line but theirs filled up the whole paper and the colours are totally different from the start. o.o^lll

lab safety rules

this is just a short clip about lab safety and what would happen to you if you do not follow it. (if you could consider it short) maybe you can really hear this first clip well so i posted a new one which is bellow.

i just realised that all the videos are all black and white. 0(>.<)0
