What are air particles doing in an undisturbed state?

Biology
1 answer:
seraphim [82]3 years ago
4 0

Answer:

Air particles are a mixture of solids and liquids that are microscopically tiny and suspended by air currents. It can stay in the atmosphere for a few hours to a month or two. Their constituents can be various harmful substances such as heavy metals - lead, nickel, arsenic, cadmium or polycyclic aromatic hydrocarbons

Explanation:

Air particles, nitrogen dioxide and ground-level ozone are now considered to be the three most polluting substances in human health. Exposure during peak concentration and long-term exposure to these pollutants can cause damage from respiratory distress to premature death.

What is the formula for the hydrolysis of maltose?
iVinArrow [24]

Answer:

Maltose

Explanation:

Maltose consists of two molecules of glucose that are linked by an α-(1,4′) glycosidic bond. Maltose results from the enzymatic hydrolysis of amylose, a homopolysaccharide (Section 26.9), by the enzyme amylase. Maltose is converted to two molecules of glucose by the enzyme maltase, which hydrolyzes the glycosidic bond. Commercial maltose is produced from starch that has been treated with barley malt.

The monosaccharide unit on the left is the hemiacetal of the α-d-glucopyranosyl unit. It is linked by an α-(1,4′) glycosidic bond to β-d-glucopyranose, the aglycone. The oxygen atom of the glycosidic bond is approximately in the center of the structure, between the two rings. It is projected down, axial, and therefore α. It is linked to C-4 of the aglycone, and so the link is axial–equatorial.

Maltose has a more formal, IUPAC of name: 4-O-(α-d-glucopyranosyl)-β-d-glucopyranose. This rather forbidding name is not quite as bad as it looks. The term in parentheses refers to the glucose unit on the left, which contributes the acetal portion of the glycosidic bond. The term -pyrano- tells us that this part of the structure is a six-membered ring, and the suffix -osyl indicates that the ring is linked to a partner by a glycosidic bond. The prefix 4-O- refers to the position of the oxygen atom on the aglycone, the right-hand ring. The term β-d-glucopyranose describes the aglycone.

Because the aglycone is a hemiacetal, maltose undergoes mutarotation. For the same reason maltose is a reducing sugar. The free aldehyde formed by ring opening can react with Benedict’s solution. The acetal part of the structure is called the “nonreducing end” of the disaccharide. If we do not want to specify the configuration of the aglycone, we use the name 4-O-(α-d-glucopyranosyl)-d-glucopyranose.

A protein has been used by comparative molecular biologist to show the evolutionary path of how organisms did what things in reg
Anit [1.1K]

Answer:

Cytochrome C; it provides evidences that there is similarities in the respiratory pathways for producing ATPs by  all living organisms especially mammals.

Explanation:

Cytochrome c is located in the intermembranes of mitochondria, and it functions in the transfer of  of one electron in electron transport chain,(ETC) needed for  generation of proton motive force;  for generation of energy in the synthesis of ATPs by ATPase synthase  during chemiosmosis. Its allows oxdation-reduction by the switching of its iron ii to iron iii. during electron transports.However its iron atoms does not undergo oxidation with  oxygen. This feature makes it stable and  an ideal carrier of electrons.

Its amino acid sequences is very similar in all living organisms especially  between mammals(e.g man and chimpanzees)with little variation in few amino acid residues due to mutation.This similarity in its amino acids sequences in all  living  organism together with small molecular size makes it ideal  molecular evidence  for studying comparative molecular evidence of  evolution.

This is because it can be used  to trace  the pathways of respiration to synthesize energy, and therefore to conclude that  most  organisms share common ancestry, since a very similar protein sequence in  a structure(Cytochrome c) participated in unique ETC mechanisms  in all, needed for energy synthesis .

what are your bones made up of? please list them all! (if you answer correctly, i will mark branliest!)
zheka24 [161]

Answer:

Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
