Human blood types are characterized by the presence absence of surface markers known as a tigers on the surface of red blood cel
zalisa [80]

Answer:

characterized by presence or absence of antigens

the blood types are A, B, O, AB

Explanation:

There are two antigens and two antibodies that are mostly responsible for the ABO types.  The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens  are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.

Blood group   Antigen present on RBC    Antibodies in serum    Genotype(s)

      A                        antigen A                             anti-B                     AA or AO

      B                        antigen B                             anti-A                     BB or BO

      AB              both A and B antigen                 none                         AB

      O                           none                           anti-A and anti-B           OO

The splitting apart of two organic molecules in a polymer and adding back the water parts to make individual monomers again is c
Pani-rosa [81]

The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.

<h3>What is hydrolysis?</h3>

The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.

Practically speaking, hydrolysis refers to the process of separating compounds when water is present.

Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.

The three primary hydrolysis processes are

  • Salt hydrolysis.
  • Acid hydrolysis.
  • Base hydrolysis.

malfutka [58]

An infectious disease researcher isolates the pathogen responsible for an emerging disease. The microbe is grown in the lab. Preparation of the laboratory-grown microbe is treated with a lethal dose of ionizing radiation and then tested for its potential as a vaccine and this is  Inactivated type of Vaccine.

<h3>What exactly are pathogens?</h3>

Pathogens include viruses, bacteria, fungi, and parasites that can enter the body and harm the immune system. Among many additional viruses that can lead to serious illnesses are anthrax, HIV, the Epstein-Barr virus, and the Zika virus.

<h3>What is vaccination?</h3>

An easy, secure, and reliable method of preventing hazardous infections before you are exposed to them is vaccination. It boosts your immune system and builds up your body's natural defenses against particular infections.

<h3>Inactivated vaccine:</h3>

In inactivated immunizations, the disease-causing microorganism is eliminated.

Inactivated vaccines typically don't provide as strong of immunity (protection) as live vaccines. Therefore, it can take several doses (booster injections) throughout time to keep up your resistance to diseases.

Using inactivated vaccinations, you can guard against

  • Flu
  • Hepatitis A
  • Polio
  • Rabies
