IgG antibody isotype to antigen can inhibit naive b lymphocyte activation of pre existing (already present).

Proteins called antibodies defend you when your body comes into contact with an unwelcome chemical. Antibodies, which are made by your plasma, bind to these foreign substances and drive them out of your body.

Immunoglobulin is another name for an antibody.

Antigens have molecules on their surfaces that are different from those your body naturally produces. Therefore, as soon as an antigen enters your body, your immune system immediately recognises it. Your immune system requests antibody defence in order to combat this antigen invader.

The B cell produces antibodies (specialized white blood cells). A B cell multiplies and clones when it comes into touch with an antigen. These plasma cells, also known as cloned B cells, unleash countless amounts of antibodies into your lymphatic and blood systems.

Your body has antibodies in a number of places, including your skin, lungs, tears, saliva, and even breast milk. In actuality, colostrum contains significant amounts of antibodies. Because of this, breast- or chest-feeding can strengthen your baby's immune system.

The difference between reactions mediated or not by enzymes, is the speed at which they occur, and hence, the required activation energy. A) The presence of the enzyme decreases the activation energy.

Enzymes are proteins with intracellular catalytic properties that accelerate different natural chemical reactions. These reactions occur naturally, but they are accelerated in the presence of the enzyme.

Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they need an accurate tridimensional structure to accomplish their function. There is a limited temperature and pH level at which they lose that structure and denaturalize.

Concerning the reaction, in the enzyme's presence and absence, the substrate and the product are the same.

The main difference is the activation energy required to carry out the reaction.

Let us remember that activation energy is the one required to create or break bonds between molecules. Usually, the higher the activation energy is, the slower the reaction occurs.

In the presence of the enzyme, the reaction needs a lower activation energy than in its absence.

According to this framework, the correct option is A. The presence of the enzyme decreases the activation energy.

Note: Since I could not find the complete question, I will attach a graph showing the progress of a chemical reaction with and without the presence of an enzyme. This diagram should be the same as yours.

The characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.

Hemoglobin is a two-way respiratory carrier that facilitates the movement of carbon dioxide back and forth from the lungs to the tissues. Hemoglobin's affinity for oxygen in arterial circulation is high, but its affinities for carbon dioxide, organic phosphates, hydrogen, and chloride ions are low.

Thus from above conclusion we can say that the characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

Meiosis produces haploid gametes, and fertilization creates a diploid cell that divides by mitosis to produce a new individual.
Understanding meiosis
One method of cell division is meiosis.  Reporting from the official website of the Ministry of Education and Culture of the Republic of Indonesia, meiotic division only occurs in the sex organs.
The function of Meiosis is to produce gametes (egg cells and sperm cells).  This division produces daughter cells that have half the chromosomes of the parent cell.
The number of chromosomes possessed by daughter cells is n or is called haploid.  Hence, meiotic cell division is referred to as reduction division.
Meiosis is a cell division thatthat produces 4 daughter cells, each of which has half the number of chromosomes of the parent cell.
And while body cells carry a total of 46 chromosomes, gamete cells only carry 23 chromosomes.  A healthy young adult male will produce several hundred million gametes each day.  In women, sex cells or ovum development follows a long process, starting in the fifth month after the woman is conceived.  Meiosis begins at this stage, but stops at the egg precursor cell stage – or primary oocyte – during fetal development.

Generally, the more food in the stomach, the faster the absorption rate of alcohol the statement is false.

A serving of alcohol needs between 30 and 2 hours after intake to completely enter the bloodstream. Alcohol is metabolized by the body at a rate of 0.25 ounces per hour. It is significant to remember that gender might affect how quickly alcohol is absorbed.

A person's ability to absorb alcohol can vary depending on their gender; for instance, a 140-pound male can consume two drinks in an hour and have a blood alcohol level of 0.038, whereas a 140-pound female can consume two drinks in an hour and have a blood alcohol level of 0.048.

Evolution is defined as  gradual change to the DNA of a species over many generations.

Palaeoanthropology is the scientific study of human evolution

Human evolution is the lengthy process of change by which people originated from apelike ancestors

It can occur by natural selection, when certain traits created by genetic mutations help an organism survive/reproduce. These mutations will pass onto next generation.  

On our recent study of DNA, we can see evidence that natural selection has recently made changes, so evolution will never stop.

There are several signs of human evolution-

1. The adaptation to the threat of infectious diseases and High prevalence of diseases like  sickle cell disease and thalassemias

2. Also. deviations from expected allele frequencies provide clues that genes have undergone selection.
