WHAT IS NOISE POLLUTION? Not all sound is considered noise pollution. The World Health Organization (WHO) defines noise above 65 decibels (dB) as noise pollution. To be precise, noise becomes harmful when it exceeds 75 decibels (dB) and is painful above 120 dB.
Our study provides evidence that high-fat diet consumption leads to renal lipid accumulation, increases inflammatory cytokines, induces glomeruli retraction, and renal dysfunction.
Sound waves enter the outer ear and travel through a narrow p****ageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.
Here is a song I created for my 6th grade science students. I hope you enjoy
Molecules through the membrane
Selectively permeable part
Diffusion where molecules moving
High to low is this sort
They tell me water p****es out and in
Through the permeable membrane
Well osmosis how the diffusion of water goes by
Water that cells need
In diffusion molecules moving
Goes from higher to the lower
Osmosis water p****ing in/out
Of cells makes it swell or get small
So both these types don't need energy
They are forms of p****ive transport
Active while moving from low to high
Requires use energy to cross
Cell absorbing substance from the world
Cell membrane will p**** objects
Both the in and out is p****ive transport
No energy for process
What if cell needs to use power to run
move molecules in reverse?
Active transport use special proteins
Picks up and immerse
In diffusion molecules moving
Goes from higher to the lower
Osmosis water p****ing in/out
Of cells makes it swell or get small
So both these types don't need energy
They are forms of p****ive transport
Active while moving from low to high
Requires use energy to cross
Requires energy to cross
Requires energy to cross
Requires energy to cross
Requires energy

Lyrics:
If you're in a cell's cytoplasm, heading outside,
Your last stop's a barrier, 8 nanometers wide,
The cell membrane: our subject for today
It's as basic to life as DNA
It's Selectively permeable, like a border patrol
of a country it maintains control.
Selecting what leaves or what gains entry
It's a guard, bouncer, watchman, patrolman or sentry.
But not just a guard, it sends signals in nerves
White blood cells use their membranes to eat germs like hors d'oeuvres,
Membranes have receptors, enzymes and junctions,
So what kinds of structure can have all these functions?
CHORUS
C-E double L, "Mem" B-R-A-N-E
Controlling transport selective permeability
Phospholipids, Carbohydrates, Proteins and Cholesterol
The Fluid Mosaic Bilayer in us all
So let's take a look at what makes up the membrane,
Phospholipids rule this domain,
In fact membrane structure emerges directly
from phospholipids' chemical properties.
There's a head and a tail on every phospholipid,
The tail's two long chain fatty acids
Bound to a glycerol, it's made to order
The tail's non-polar --hydrophobic-- fears water
The head's got a phosphate, it's charged negatively,
makes the head hydrophilic--plays in water happily
So tail avoids water while the head's attracted to it,
When phospholipids form the membrane that's how they do it.
Cause when phospholipids into water get submerged,
A phospholipid bilayer structure will emerge
The tails hang together in a water free zone,
Hear their hydrophobic moan, "water leave me alone!"
While the heads are sticking out touching all those H2Os
Tails in, heads out, it's how every membrane goes
Tails in, heads out, in a cellular sphere,
It's the bilayered basis of membranes everywhere.
CHORUS
But a cell membrane's not just a phospholipid scene
There's cholesterol, carbohydrates, lots of proteins.
In fact, membrane proteins have a presence so great,
that they often exceed the phospholipids by weight.
And all of these components are in constant motion,
Moving, mixing like a boiling potion,
Flowing like dancers in a party in Pasaic
That's why the membrane's thought of as a fluid mosaic.
Let's start with proteins since they're key in this mix.
Transmembrane proteins span the entire width.
Typically they're ports--think of channels or conveyors,
For things that don't go through the lipid bilayer.
Any protein embedded in the hydrophobic middle
Built right into the inside is considered integral
While peripheral proteins either hang on the exterior,
Or inside on the cytoplasmic interior.
Cholesterol keeps membranes flowing with ease,
In cold it keeps the lipids moving so they don't freeze,
In heat it slows the lipids down limiting their traveling,
Cholesterol: it keeps membranes from unraveling
Membrane carbohydrates work as markers or signs
So your immune system knows which flag your cells are flyin'
The blood types AB, O, and B and A
Are about the carbohydrates on red blood cell membranes.
CHORUS
Summary of some of the best science parody songs out there right now.
Mixtures can be separated using a variety of techniques. · Chromatography involves solvent separation on a solid medium.
Water pollution is the contamination of water sources by substances which make the water unusable for drinking, cooking, cleaning, swimming, and other activities. Pollutants include chemicals, trash, bacteria, and parasites. All forms of pollution eventually make their way to water.
A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution. Unlike biodegradable wastes, non-biodegradable cannot be easily handled. Non-biodegradable wastes are those that cannot be decomposed or dissolved by natural agents.
Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution.

NUCLEUS:
Welcome to the plant cell
time to introduce
I’m the nucleus
I run this clique
you know I got the juice
an envelope has got my back
I’m the #1 OG
which is short for “Organelle”
So let’s meet the family!
CELL WALL:
First up the cell wall
Here’s to tell y’all
I hold the cell up so it don’t fall
I stand tall
keep us shaped up
square so we don’t look whack
‘cuz you know plant cells
are stacked on stacks of stacks...
CELL MEMBRANE
And if you wanna get in
I maintain
you gotta get past me
Who? The cell membrane!
Regulating what comes out and goes in
like a door man
I’m letting all my bros in
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!
MITOCHONDRIA:
Can I go next?
NUCLEUS:
Hold up mitochondria — you’re the powerhouse of the cell, man, they aint ready for you!
MITOCHONDRIA:
Awww, okay…
NUCLEUS:
E.R. — hit us with that fire!
ENDOPLASMIC RETICULUM:
Last name: Reticulum
First: Endoplasmic
Haven’t heard of me? Well
That’s tragic
Moving proteins from one spot to another
They’re made by ribosomes
NUCLEUS:
Who dat?
ENDOPLASMIC RETICULUM:
My baby brother!
CHLOROPLAST:
Woah woah!
slow your roll
Hand on the mic, I’m in control
No need to move so fast
‘cuz now
you’re dealing with the chloroplast!
Got a nice fat sack of chlorophyll
so looks like it’s about time time to get chill
sun rays beat down like a sizzle
so Photosynthesizzle what I do fo’ rizzle
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!
MITOCHONDRIA:
Ok NOW can I go?
NUCLEUS:
Ok Mitochondria, go for it!
MITOCHONDRIA:
Alright, just need to take a quick breath first…
MITOCHONDRIA:
I gotta move quick
I gotta move fast
In the plant cell clique
with Chloroplast
We work together, see?
Photosynthesis to energy
I make it look easy
So run & tell that & don’t step to me
I’m the finest MC
in the microscopic nation
take a deep breath
call that cell respiration
powerhouse
I power up
My engine drives that flower up
Not bragging, just to tell ya
Zinnia to Azelia, Photosynthesis won't fail ya!
We are the parts of the plant cell
this flow gets growing and we represent well
getting energy from rays of light
making mitosis by the end of the night
we are the parts of the pant cell, yeah!

All leaves change sunlight into energy through photosynthesis. The leaves are the primary food-making part of the plant. Leaves absorb carbon dioxide from the air, combine it with water that comes through the roots of the plants to make food (a sugar molecule known as glucose), and release oxygen into the air.
Greg Mendel and Meiosis Song. Here is a video I created for my 6th grade science students to help them study.I hope you enjoy. Greg Mendel
Greg Mendel
Greg Mendel
He did it again, so I'm gonna let the beat drop
Greg Mendel
Mendel had a
Mendel had a
Mendel had a
Chorus
Mendel had a garden
There's so many different pea plants
They had different kinds of seeds
Some green and some were yellow
Then he thought, Oh my gosh, different traits
He found heredity, he makes me wanna say
Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh,
Greg Mendel
Chant (Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh) He makes me wanna say
Chant (Oh, oh, oh, oh, oh, oh, oh, oh,) Oh, oh, oh, oh, oh, oh, oh, oh, oh
Mendel made a wise decision when he chose to study peas
They are either really t-t-tall or short, and droppin' low
Mendel crossbred pea plants they were either tall or small
Parent Generation; this is what he called them
All of the plant offspring were tall, tall, tall
He was so surprised he said, Wow, oh, wow
Then F-Generation, pollinated themselves
Tall, tall, tall, Small, But how could that be 'cause
None of the parents were small
Then he checked for other traits
Color, seed coat, and all, and all, and all
Chorus
It's dominant, recessive genes
Alleles control inheritance
Let's set up a Punnett Square
Genetic possibilities
Phenotype is physical, visible
But Genetic Mix is Genotype,
He makes me wanna' say
Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh,
Greg Mendel
Chant (Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh ) He makes me wanna say
Chant (Oh, oh, oh, oh, oh), He makes me wanna say, Oh, oh, oh, oh, oh, oh, oh, oh, oh
Meiosis is where cells will split to end with half the number
Chromosomes for sex cells, egg and sperm pair with each other
Every chromosome is copied, they're held together,
Oh, oh, oh, oh, oh, oh, oh, Meiosis 1
Pairs line up the middle then, spread apart
Two cells form with half the number, split apart
Chromosomes are double stranded-not for long
This is all repeated in Meiosis 2
Centromeres split each strand into two
Four sex cells have been produced
Now with a chromosome, from each, first pair.
Half-time Chorus
Mendel had a garden
There's so many different pea plants
They had different kinds of seeds
Some green and some were yellow
Then he thought, Oh my gosh, different traits
He found heredity, he makes me wanna say
Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh,
Greg Mendel
Chant (Oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh, oh) Greg Mendel

The skin also acts as an excretory organ. It is estimated that 3 to 4 million eccrine sweat glands which together roughly weigh the same as one kidney (i.e., 100 g) are distributed over almost the entire human body surface.
Here's how to write formulas for binary ionic compounds. We'll see how you have to balance the charges of the two ions so they cancel each other out.
