After first exposure to an antigen, it can take about three weeks for antibodies to reach a detectable level. The body will react to disease by creating antibodies and testing their effectiveness against the unknown antigen.
Antibodies are the body's way of fighting off foreign threats. Also known as immunoglobulin, they detect and attack pathogenic bacteria and viruses. These antibodies detect a protein that is unique to the surface of the pathogen called the antigen.
At times, we can see an increase in antibodies for one disease, for example, Lyme disease, in the presence of non-Lyme disease antigens. This is often due to antigenic variation, which is a method used by pathogens to mask their respective antigens. There are also general use antibodies that will increase in reaction to any pathogen.
As with any illness, a patient who receives treatment sooner will fare better than those whose treatment is delayed. This is due to the fact that earlier treatment with antibiotics will allow the body to fight off the infection before the bacteria can reproduce further.
After the first immune response, antigen-specific antibodies will remain for some time to provide the body with "immunity" to the pathogen, while general-purpose antibodies will return to a base value.

Answer:
Denature
Explanation:
Denature
Answer:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
ExplanatioEnzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
Reaction coordinate diagram showing the course of a reaction with and without a catalyst. With the catalyst, the activation energy is lower than without. However, the catalyst does not change the ∆G for the reaction.
Active sites and substrate specificity
To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates.
In some reactions, one substrate is broken down into multiple products. In others, two substrates come together to create one larger molecule or to swap pieces. In fact, whatever type of biological reaction you can think of, there is probably an enzyme to speed it up!
The part of the enzyme where the substrate binds is called the active site (since that’s where the catalytic “action” happens

Normally, the flexible, round red blood cells move easily through blood vessels.
Explanation:
Based on "Sickle cell anemia is an inherited red blood cell disorder" taken from the text, I would say the correct answer is C, because it says "an inherited disorder" and describes Sickle cell anemia.

You have recently identified a new toxin. It is produced by a gram-negative bacterium. It is composed mostly of protein, has high toxicity, and is not heat stable. You also discover that it targets liver cells. Based on these characteristics, how would you classify this toxin
Based on the characteristics above, this toxin can be categorized as EXOTOXIN. These toxins (exotoxins) are produced by different types of bacteria.
Exotoxins are a broad category of proteins produced by bacteria that enter host cells in order to alter their physiological properties.
These toxins (exotoxins) can be secreted by Gram-negative bacteria and Gram-positive bacteria.
Examples of exotoxins include botulinum toxin secreted by Clostridium botulinum bacteria, tetanospasmin toxin secreted by Clostridium tetani bacteria, etc.

2. What is meant when describing water as a polar compound?
Please answer what the question is asking exactly many points will be given.
Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution
Which of the following BEST describes the length of days in Australia when the Earth and sun are positioned as shown in January in the diagram above?
long days.
continual daylight.
short days.
continual darkness.
Answer:
B is the answer
Explanation:
continual daylight
In the given image it is showing long days. The correct option is A.
What is the relation between day and night?The Earth orbits the sun once every 365 days and rotates once every 24 hours on its axis.
Day and night are caused by the Earth rotating on its axis rather than by its orbit around the sun.
The term "one day" refers to the time it takes the Earth to rotate once on its axis and includes both day and night time.
A day is roughly the time it takes for the Earth to rotate or for other large astronomical objects to rotate.
The number of daylight hours we have depends on our latitude and how the Earth orbits the sun.
The axis of rotation of the Earth is tilted relative to its orbital plane and always points in the same direction means toward the North Star.
Thus, the correct option is A.

_____ is the process by which energy is stored in inorganic molecules is used to produce carbohydrate food molecules
Answer:
Chemosynthesis
Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecules.
that is the answer
Photosynthesis is the process by which energy stored in inorganic molecules is used to produce carbohydrate food molecules.
What is photosynthesis?Photosynthesis is the primary process by which plants, algae, and some bacteria capture and store energy from the sun.
During photosynthesis, light energy is absorbed by pigment molecules in the chloroplasts of plant cells. This energy is then used to convert carbon dioxide (CO2) and water (H2O) into glucose (C6H12O6) and oxygen (O2). The glucose produced during photosynthesis is used by the plant as a source of energy and is also stored as a carbohydrate reserve. The oxygen produced during photosynthesis is released into the atmosphere as a byproduct.

What is recombinant DNA ?
Recombinant DNA are the molecule which has been modified to include genes from different origin by the process of either genetic recombination or through laboratory techniques.
In the lab condition, bacteria can be transformed with recombinant DNA and Genetic recombination occurs via crossing over.
scientists use this recombinant DNA technology created to add to the genome of another organism which means that scientists can easily add genes from one species into bacteria for the production of the product.
For example, insulin is produced by recombinant DNA technology within bacteria where human insulin gene is inserted into a plasmid, then introduced to a bacterial cell, followed by the production of insulin by bacteria cell.
