This image is a partial lunar eclipse. The moon is only showing partially, so it's not total, and the brighter side is showing.
<span>The
answer is Helium-4. These are two protons and two neutrons bound together. Alpha radiation
is the least powerful of the 3 types of radiation: the others being gamma and beta. Nonetheless,
it is the most densely ionizing. Alpha and beta radiation
release actual matter while gamma emits electromagnetic

How are DNA fragments separated using gel electrophoresis? ... A solution ofDNA molecules is placed in a gel. Because each DNA molecule is negatively charged, it can be pulled through the gel by an electric field. Small DNAmolecules move more quickly through the gel than larger DNAmolecules.Nov 20, 2007
Answer:
The correct answer is option a. "7.1".
Explanation:
One easy way to determine if a peptide sequence is acidic, basic or neutral is to check for the number of amino acid residues that are acidic, basic or neutral. In this case, most amino acid residues are neutral, which mean that under neutral conditions they have a pKa close to 7.0. Particularly, the content of 3 leucine, 2 alanine and 2 glycine residues determines that the peptide have a pI of around 7.1.
Answer:
Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.
Explanation:
Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.
In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.
Basically, the normal blood pH of a human being should be between 7.35 and 7.45.
Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.
For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.
In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.
