is hb2 same as h4?

9003 and HB2 are different names for the same bulb, so these numbers apply to just two kinds of bulb: H4 and 9003/HB2. ... Motorcycles in the USA have never been required to use sealed beam headlamps, and so the H4 bulb became popular for motorcycles in the US and worldwide. It is widely used to this day.

In conclusion, a simplified relationship of Hb (g/dL) = (0.3 PCV) + 3 may provide a better estimate of Hb concentration from the PCV of cattle. It is, therefore, recommended that if it is necessary to estimate Hb concentration from PCV value, then the simplified relationship may be more appropriate to use.

Hemoglobin is made up of four subunits: two subunits of alpha-globin and two subunits of another type of globin. Alpha-globin is a component of both fetal hemoglobin, which is active only before birth and in the newborn period, and adult hemoglobin, which is active throughout the rest of life.

Hemoglobin (American English) or haemoglobin (British English) (Greek αἷμα (haîma, “blood”) + -in) + -o- + globulin (from Latin globus (“ball, sphere”) + -in) (/ˈhiːməˌɡloʊbɪn, ˈhɛ-, -moʊ-/), abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells (erythrocytes) of almost ...

The number 2 pencil is a 2H. The HB is softer than the H2. After HB are the B pencils that progress from B to the B6 which has the softest lead (graphite), which produces the widest and darkest line.

Although today most pencils using the HB system are designated by a number such as 2B, 4B or 2H to indicate the degree of hardness. ... Generally, an HB grade about the middle of the scale is considered to be equivalent to a #2 pencil using the U.S. numbering system.

Hemoglobin is the principal protein inside of red blood cells and accounts for one-third of the mass of the cell. During the conversion of CO2 into bicarbonate, hydrogen ions liberated in the reaction are buffered by hemoglobin, which is reduced by the dissociation of oxygen. This buffering helps maintain normal pH.

Hemoglobin is the protein inside red blood cells. It carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.

Sickle hemoglobin differs from normal hemoglobin by a single amino acid: valine replaces glutamate at position 6 on the surface of the beta chain. This creates a new hydrophobic spot (shown white).

Generally, an HB grade about the middle of the scale is considered to be equivalent to a #2 pencil using the U.S. numbering system. In reality however, there is no specific industry standard for the darkness of the mark to be left within the HB or any other hardness grade scale.

Hepatitis B and hepatitis C are both viral infections that attack the liver, and they have similar symptoms. The most significant difference between hepatitis B and hepatitis C is that people may get hepatitis B from contact with the bodily fluids of a person who has the infection.

Yes, 2H is harder than HB. The HB pencil is the middle of the road pencil in that it is in the middle of the scale measuring hardness and blackness. The blacker the pencil, the softer it is. The harder the pencil, the lighter the marks it will make.

It is the iron atom that binds oxygen as the blood travels between the lungs and the tissues. There are four iron atoms in each molecule of hemoglobin, which accordingly can bind four atoms of oxygen. Globin consists of two linked pairs of polypeptide chains.

4 grams (2 moles) of hydrogen molecules contains 4 moles of hydrogen atoms.

The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
