Describe how a vehicular texture is produced in a volcanic rock
SVETLANKA909090 [29]
When this happens gasses dissolved in the magma are able to come out of solution, forming gas bubbles (the cavities) inside it. When the magma finally reaches the surface as lava and cools, the rock solidifies around the gas bubbles and traps them inside, preserving them as holes filled with gas called vesicles.

In general, the ld50 for exotoxins is much greater than the ld50 for endotoxins.
storchak [24]
FALSE!!
Endotoxins are just the lipid parts of a gram negative cell wall that have broken off when the bacteria dies. They are moderately toxic, cause fever and can make you pretty sick.
Exotoxins are proteins made by pathogenic bacteria (mostly gram positive). These highly toxic. Examples of diseases caused by these are diphtheria, botulism and tetanus. 
Therefore it doesn't take much exotoxin to cause a problem!

  • As the species of peas would begin thriving after predation, it would genetically learn to grow up to adapt to the external condition on its own.
  • This would cause the species to develop immunity against factors defiant for its growth and thrive in the given conditions after predation.
  • Hence, split peas would group and multiply to become the most frequent sub-species.
