The body recognizes after the body has been presented with or dealt with the pathogen before. the immune system defends against pathogens and the immune system then after recognizes the pathogen when the pathogen has been killed. the pathogen is recognized through the proteins presented on its surface. vaccinations contain pathogens but in small amounts in which the body can control and defend against, after the body has killed the pathogens it will later recognize it and defend better
It could be cooled which would then cause it to become over-saturated resulting in condensation that would return the air to a saturated state. Over-saturated air, with a humidity greater than 100%, is unstable, causing changes to restore stability. Hope this helps!
I am: A) DNA
DNA is double-stranded molecule which is often also it's most known feature. Perhaps less known (depends on who you ask) are facts that it also has thymine and not uracil (uracil is found in RNA). It has four nitrogen bases and it contains deoxyribose sugar (another hint that it's DNA and not RNA).
1: to produce daughter cells with half the number of chromosomes that are in parent cells.
Answer:
Through the study of meteorites, their chemical composition of silicates—material made of silicon and oxygen. Others contain metal—nickel and iron. Knowing what the meteorite was composed of lets you know where it came from. Chondrites are composed of hardened lava - this is occurred at the beginning of the solar system (4.5 mya). Carbonaceous chondrites contain carbon and water which formed away from the sun.
