You are infected with a pathogen; it is your first exposure to this pathogen. The first antibody types that will eventually appear in your blood to help fight this infection will be:
If it is the first time that this pathogen comes into contact with the immune system, IgM antibodies are produced, which are the first type of antibodies produced against a certain microorganism.
Immunoglobulins are molecules that intervene in defense processes against microorganisms and infections.
Each type of immunoglobulin is specific against a certain antigen, this is what allows an immunological memory to exist, which is obtained when coming into contact for the first time with a certain microorganism.IgM is the first immunoglobulin synthesized by the neonate by itself, and it is also the first to appear during the primary response, which lasts an average of three weeks and then disappears.In general, the production of IgM antibodies precedes that of IgG, the concentration of antibodies can be high, plateau for a few days and then decrease rapidly.Therefore, we can conclude that when the immune system first comes into contact with an antigen, a primary response occurs; mediated by IgM antibodies.

2. What do you notice about the cellular respiration and
photosynthesis equations?
Answer:
Photosynthesis and cellular respiration are connected through an important relationship. ... Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O

What is one reason that the surface water at the equator is less dense than
the surface water at the poles?
Answer: At low latitudes, near the equator, direct overhead sunlight received all year warms surface waters.
Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.
Explanation:
Answer:
The density of ocean water is so varied, that while there may be a generally considered variation due to temperature, taking random samples in a wide variety of places, thus you can distinguish no real pattern.

(c) In soils that lack oxygen, plants cannot absorb enough nitrates from the soil to grow well. Explain why.
Answer:
Explanation:
Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. ... This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

Crime-scene work often involves obtaining a DNA sample from a drop of blood to help identify persons who may have been involved. Frequently, the size of the DNA sample is extremely small, too small for easy analysis. Which of the following laboratory procedures could criminologists use to amplify the amount of DNA present?
A: Cloning and gel electrophoresis
B: Cloning and polymerase chain reaction (PCR)
C: DNA splicing and polymerase chain reaction (PCR)
D: Vector amplification and DNA splicing
Amplification of DNA is a very useful tool in the study of the human genome. DNA amplification ensures the production of multiple copies of the needed segment.
Criminologists can use Cloning and PCR to amplify the amount of DNA present...
Cloning involves creating identical copies of a particular DNA segment in study. Then amplification of the DNA using polymerase chain reaction will aid in amplifying and producing thousands of these copies of short targeted segments in minutes. This tool is very useful in ensuring the multiplication of that particular targeted sequence for analysis.Learn more about PCR: https://brainly.com/question/20757028
