after water, which are the next most abundant substances in the human body?
Answer:
Proteins
Explanation:
After water, Proteins are the next most abundant substances in the human body.
In adult men , 60% of body is comprised of water whereas in women , 55% of body is comprised of water.
Protein makes up around 20% in body and is present in every cell.
What are Proteins?Proteins are large complex molecules and play critical roles in the body. They do most of the work in their cells and required for structure functions and regulation of body tissues.
Proteins are made up of smaller units called amino acids, which are attached to one another in long chains.
There are 20 different types of amino acids that can be combined to make a protein.
The sequence of amino acids determines about each protein’s unique 3-dimensional structure and its specific function.
Amino acids are coded by combinations of three DNA building blocks (nucleotides), determined by the sequence of genes.
Functions of Proteins:
1. As an Antibody- Bind to specific foreign particles such as bacteria and virus to help protect the body.
2. As an Enzyme- Carry out thousands of chemical reactions taking place inside the cell
3. As a Messenger- Transmit signals to coordinate biological processes between different cells, tissues and organs.
4. As a Structural Component- Providing structure and support to cells.
5. Transport/Storage- Binding and carrying atoms and small molecules within cells and throughout the body.

which type of microscopy allows us to clearly view the internal contents of cell structures smaller than 200 nm?
Because the cell structures are so small, to clearly view them, requires a microscope that has a higher power of magnification than light microscopes can prove. This is usually an Electron Microscope.
Electron microscopy (EM) is a technique used to obtain high-resolution images of biological and non-biological specimens. It is often used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes. (UMass Chan Med School Website)
suppose you and a friend are making iced tea using identical glasses. You both use the same amount of water, and the water temperature is the same in both glasses. Explain how you can tell who added more ice tea mix to the glass.
Answer:
Iced-Tea Problem
220 g of 35˚C tea (water) is poured over 250 g of -10˚C ice.
What happens...
The warm water (tea) will cool down to 0˚C. As it cools the ice will heat up to 0˚C and then start to melt.
There is plenty of ice however and only a portion of it will melt. Find the amount of ice that melts into water
and you’ll know the final composition and even the dilution factor on the tea.
Cool tea water down to 0˚C
4.184 J/g˚C · 220 g · 35˚C = 32216.8 J removed to cool tea to 0˚C
Warm ice up to 0˚C
2.09 J/g˚C · 250 g · 10˚C = 5225 J to heat ice up to 0˚C
This heat comes from the cooling water, so substract this amount off the total above
32216.8 - 5225 = 26991.8 J of heat that will MELT the ice
mass of ice melted = 26991.8 / 334 = 80.8 g of ice melted
220 g + 80.8 = 300.8 g of water
250 g - 80.8 = 169.2 g of ice
final mixture for
my glass of iced
tea all at 0˚C
220.0 g original tea
300.8 g final tea
The dilution factor is simply the original volume
over the final volume (or masses here ). = .731 or 73.1%
of the original
concentration
If I’m going to get a dilution of 73.1%, I should
compensate by mixing my tea in 26.9% LESS
volume than the directions state. So I will not dilute
the tea to 2 quarts (64 oz), but rather to 1.462
quarts (46.8 oz).
It’s hot and I want a glass of iced tea as soon as possible. The directions for my tea say to boil some water,
add 2 tea bags (these are the big bags), steep for 4-5 minutes, then add enough water to make 2 quarts which
turns out to be a pitcher of tea. However, if I make this tea the exact concentration I want now, when I pour
it over ice the ice will melt (because the tea will still be quite warm) and my tea will be too dilute. So I
calculate how much stronger I should make the tea KNOWING I will pour the warm tea over ice to make
my glass of iced tea.
(a). What is the final temperature and composition of the glass of iced-tea?
(b). What will be the concentration of the tea relative to the original concentration?
(c). How concentrated should I mix the tea knowing that it will be diluted when
poured over the ice?
(a)
(c)
(b)
only 73.1% of the full
amount to compensate
for dilution

What is the difference between El Nino and La Nina in science terms of climate?
Answer:
El Niño impacts weather systems around the globe, triggering predictable disruptions in temperature, rainfall and winds. La Niña is the opposite – a cooling phase of ENSO that tends to have global climate impacts opposite to those of it. El Niño refers to the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific. It represents the warm phase of the ENSO cycle. La Niña refers to the periodic cooling of sea-surface temperatures across the east-central equatorial Pacific.
Hope this helps
Answer:
Well, El Niño(warmer environment) impacts weather systems around the world, while La Nina(cold environment) tends to have global climate affects opposite to El Nino.

what route does a red blood cell take to travel from the lung to the kidney
Answer:
aorta
Explanation:
the red blood cell goes into the kidney trunk and other lower limbs delivering oxygenated blood around the body. They typically last for 120
days before they die.
The blood enters the heart from left atrium. It leaves through the mitral valve into the left ventricle of the heart. The left ventricle then pumps blood through the aortic valve and into the aorta that feeds the rest of the body through a system of blood vessels.
What is function of lungs?The lungs allow us to breathe and they carry oxygen into body (called inhalation) and pass carbon dioxide out called exhalation.
Kidney remove toxins and waste, and excess water from the bloodstream, which is carried out of the body in the form of urine. They helped to produce hormones to form red blood cells, and they turn vitamin D into its active form in the body.

The word matrix can be used to describe things shaped In a pattern of lines and spaces. How does this relate to a mitochondrion?
The definition of the word matrix can be applied to the organelle known as mitochondria given that the mitochondria have what is known as a "mitochondrial matrix".
The mitochondria are amongst the most important organelle of a cell. They are responsible for the production of energy molecules in the form of ATP. The basic structure of mitochondria consist of:
Outer membraneIntermembrane spaceInner membrane MatrixGranulesand contain even more elements within.
The inner membrane of the mitochondria surrounds the matrix, giving it the form of a pattern of lines that bend and curve, leaving spaces in between. The similarity between this shape and the definition that is given of the word "matrix", explains why this structure may have been given the name of the mitochondrial matrix.

How to use bacteria as a treatment for sewage waste
Answer: hope this helps
Explanation:
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
Explanation:
Biological wastewater treatment is the most common method of sanitation in the world. This technology uses different types of bacteria and other micro-organisms for the treatment and cleaning of polluted water.
Wastewater treatment is as essential to human health as it is to environmental protection. Indeed, the use of these bacteria accelerates the treatment of pollution on a small surface: the purification plant. It’s better than letting the river handle it, because even though it’s the same purification process that occurs in nature, the quantities of pollution discharged today are too high to keep the natural cycle intact.
Thus, sewage treatment plants can prevent eutrophication of rivers, for example, but also prevent the diffusion of diseases.
Municipal and industrial effluent is the main source of wastewater. And thanks to the use of micro-organisms, we are able to degrade the content of these organic wastes as they are used as a source of food and energy to grow and multiply.
