What hormone helps maintain water and salt balance in the body?
Vasopressin, also known as antidiuretic hormone or ADH, maintains the body's water balance by promoting the kidneys to reabsorb water. ADH is secreted by the posterior pituitary gland. It works by making collecting tubules of nephrons in the kidneys permeable to water. This allows water to be reabsorbed into the body from the urine. It is also known as water retaining hormone.
Aldosterone, released by the adrenal cortex, also aids in the reabsorption of water by increasing the tubular reabsorption rate. However, it is also responsible for stimulating the tubules to reabsorb salts.
Atrial natriuretic hormone (ANH) is secreted from the atrial wall of the heart. It has the opposite effect of aldosterone. It stimulates the kidney tubules to secrete more sodium and thus lose more water.
The secretions of ADH, aldosterone, and ANH in different amounts and when needed, regulate the the body's water balance ensuring homeostasis.

What kind of organic compounds that function in building tissues and acting as enzymes?
Two organic compounds that act as enzymes are maltase and amylase. Amylase is involved in the breakdown of starch into disaccharides and trisaccharides, which are then broken down into glucose by other enzymes. Maltase is involved in the breakdown of the disaccharide maltose, a disaccharide formed when starch is broken down.
What three parts make up nucleotide?
1:A nitrogenous Base purine or pyrimidine; 2 : A pentose sugar ribose or deoxyribose ; 3: ortho phosphoric acid.
What type of biological molecules are enzymes?
Enzymes are proteins that speed up chemical reactions in our body, or in other words a biological catalyst
To heat fluid in a test tube the container should be no more than?
The test tube should be no more than half full to ensure even heating and prevent boiling or splashing of the fluid. Overfilling the test tube can cause the fluid to overflow or bubble out uncontrollably when heated, posing a safety risk.
What bonds are present in each of the four different levels of protein structure?
Primary- Covalent bonds
Secondary- Hydrogen bonds
Tertiary- Hydrophobic interactions
- Disulphide bonds/bridges
- Hydrogen bonding
Quaternary- (Same as Tertiary)
What is importance of naming chemical formula?
A compound is a substance made up of a definite proportion of two or more elements. A
chemical formula tells us the number of atoms of each element in a compound. It contains the
symbols of the atoms of the elements present in the compound as well as how many there are
for each element in the form of subscripts
Which of these is a physical property of a substance?
Physical properties include the density, color, shape, size, melting point, boiling point, and freezing point.
These are just a few properties, anything that can be observed is basically a physical property.
Chemical properties are slightly different.
Flammability is the main property.
The start and stop DNA sequences are important for ensuring proper transcription and translation of the jellyfish glo gene in the host organism. The start sequence signals the beginning of gene expression, while the stop sequence helps terminate transcription and produce a functional protein product. Including these sequences ensures successful incorporation and expression of the gene in the host.
What is the main hormone produced by males?
Males are simply always hyped up on testosterone. that is simply the only hormone known to men.
What are the characteristics of glycogen?
Glycogen is a polysaccharide that is the principal storage form of glucose (Glc) in animal and human cells.
Glycogen is found in the form of granules in the cytosol in many cell types.
Hepatocytes (liver cells) have the highest concentration of it - up to 8% of the fresh weight in well fed state, or 100-120 g in an adult.
In the muscles, glycogen is found in a much lower concentration (1% of the muscle mass), but the total amount exceeds that in liver.
Small amounts of glycogen are found in the kidneys, and even smaller amounts in certain glial cells in the brain and white blood cells.
Glycogen plays an important role in the glucose cycle
What is the function of the centrifuge step?
To achieve separation. What were you putting into the centrifuge? I know in Biochem usually centrifugation is a preparative step performed to isolate a single organelle of a cell. But centrifugation can also be analyical, for instance if you wanted to measure the density of whatever substance is in the tube.
Does photosynthesis is like cellular respiration backwards?
In cellular respiration, organic molecules and oxygen are taken in to create carbon dioxide and water.
In photosynthesis, carbon dioxide and water are taken in to create organic molecules and oxygen.
Name the component parts of a molecule of ATP?
The three components are known as adenosine triphosphate. One of the components is phosphate. Ribose is a pentose sugar. Adenine is a purine base.
What is the green part of a leaf is called?
The tissue in the interior of the leaf is called mesophyll which is the parenchyma, the essential tissue of plants. The mesophyll is divided into two groups inside a leaf; the palisade parenchyma wich is located on the upper part of leaf and the spongy parenchyma which is located on the lower part of leaf.
What are the proteins of blood?
The main proteins found in blood are albumin, globulins (including immunoglobulins), fibrinogen, and clotting factors. These proteins play important roles in maintaining blood volume and pressure, transporting substances, fighting infections, and clotting to prevent excessive bleeding.
Who best described the structure of DNA?
DNA is a linear polymer of nucleotides whose phosphates bridge the 3' and 5' positions of succesive 2-deoxy-D-ribose residues, and nitrogenous bases such as purines and pyrimidines. In detail, DNA is a) a helical molecule, and b) its planar aromatic bases form a stack of parallel rings that is parallel to the fiber axis.
There are several configurations of the DNA molecule. The A, B, and C forms of DNA are right-handed, double-stranded helices which, in fibrous form, are stable at intermediate, high, and low relative humidities, respectively, and have 11, 10, and 9.3 base pairs per turn of double helix. The left-handed helix of B-DNA structure is refered as Z-DNA (it contains 12 bases pairs per turn of double helix, and has only a single groove. B-DNA (the so-called Watson-Crick structure) is regarded as the native form because its X-ray pattern resembles that of the DNA in intact sperm heads, and is a double helix with around 20 angstroms diameter. The planes of the bases are nearly perpendicular to the helix axis and conserve the so-called "complementary base pairing" (that is, adenine base always is in front of a guanine base, as well as thymine is always in front of a cytosine.
The "ideal" B-DNA helix has 10 base pairs (bp ) per turn (a helical twist of 36o per bp) and, the aromatic bases have van der Waals thicknesses of 3.4 angstroms and are partially stacked on each other (known as base stacking). Finally, the helix has a pitch (rise per turn) of 34 angstroms.
What are structure levels of a protein?
The structure levels of a protein are primary (sequence of amino acids), secondary (alpha helices and beta sheets), tertiary (overall 3D shape of the protein), and quaternary (interactions between multiple protein subunits). Each level of structure is critical for the protein to perform its specific function.
A positively charged electron is called?
An ion with a positive charge is called a cation. Conversely, an ion with a negative charge is called an anion.
What is the difference between Evolution and Intelligent Design?
Although ID has undoubtedly become a somewhat political phenomenon, it did not begin this way. Philip Johnson, another promoter of ID conceived of it, as do others such as Michael Behe as a concept which is critical in a negative sense of existing evolutionary paradigms. The evidence used by Behe relates to the possibility of complex biological systems, which he describes as irreducibly complex, arising by the chance mechanisms of evolution. Since all the parts of these systems are required to be in place for the sytem to operate, the process of natural selection would select against the devlopment of these complex systems while they were being 'built' by the slow and gradual process of evolution.
In this sense, ID was put forward largely as a critique of evolution and points to a number of different examples which are inexplainable under current evolutionary thought. Currently there is no scientific explanation as to how the genetic information required to 'build' these structures could arise spontaneously through evolutiuonary processes.
Further to this, the science of genetics, in line with the laws of thermodynamics point to mutations as unable to add new genetic information, although recombination and duplication certainly occur, as well as certain genes being 'switched off' or 'on' with resultant effects in living things. ID theorists, although themselves criticizing evolution, or the current understanding of it, in turn come in for criticism from both evolutionists and creationists alike. The former, because they are criticizing the theory of evolution, the latter for the ID theorists reticence to name the designer.
What happens in the electron transport chain of cellular respiration?
energy in NADH2 and FADH2 used to generate ATP.3ATPs per NADH2 and 2ATP per FADH2 produced.
How can you tell if something is organic or inorganic?
That depends. An organic compound has elements made from nature itself.
An inorganic is the opposite meaning that it is made from compounds and elements that are not made from nature itself,more or less, it's kind of like manmade compounds.
Are you dumb or what? Of course not all bacteria produce urease. Most bacteria that produce urease are bacteria that are in the stomach or intestine where there is present of high gastric acidity. This urease will serve as a function to reduce the acidity and increase towards a neutral PH so that the bacteria could survive in the intestine. Otherwise without the urease, the high acidity would normally kill the bacteria.
What molecule is produced in the mitochondria and has energy stored in its bonds?
There are thousands of molecules that fit this description. The primary biochemical Cellular [mitochondria based production] Energy Transfer molecules are Adp and Atp - Adenosine di- and tri-phosphates.
