Answer:
Plasma B cells produce antibodies.
Explanation:
They can produce 1000s of antibodies every second.

Genetic drift can lead to speciation as it allows variation within the genes of a species. For instance, genetics can soon evolve into a new phenotype in a species - humans with tails, cats with gills, etc.
Therefore, genetic drift can lead to speciation as it allows variety and evolution to occur within the genetics of a species.
Hope this helps!
Answer:
The correct option is D. Thermophiles and Hyper thermophiles would be the bacterias whose enzymes would not function at 12 degrees celsius.
Explanation:
A thermophile is an organism that is acquired to live in raised temperatures and heated environments. These organisms can survive in a temperature range between 41 degrees Celsius to 121 degrees Celsius.
An hyper thermophile is an organism that is adapted to live in even more extreme heat conditions then the thermophiles.
These organisms cannot stand cold conditions and hence their enzymes would not function at 12 degrees celsius.
Low-density lipoproteins (LDLs) can contribute to the build-up of plaque that narrows blood vessels; however, LDLs are necessary because they are used to synthesize eicosanoid
<h3><u>
Explanation:</u></h3>
The article eicosanoid is practiced to include those biologically effective lipid intercessors obtained essentially from C20 fatty acids. The 'actual' eicosanoids are provided enzymatically with high stereochemical accuracy, and this is necessary for their biological purposes.
Biosynthesis of eicosanoids concerns the progress of multiple enzymes. Eicosanoids are produced largely from unesterified fatty acids, no the CoA esters, and they work in this kind, but it is frequently noticed that they may transpire and some may admittedly be incorporated while esterified to other lipids.
