Before scientist used horseshoe crab blood for the LAL test, they used rabbits to test
vaccines for contamination by bacteria. Live rabbits were injected with the vaccine and
observed for several days, Much like humans, they have a sensitivity to these bacteria.
Horseshoe crab blood is about 100 times more sensitive. Give reasons why using horseshoe
crab blood is a better way to help people and wisely use animals.

What is the main structural difference between enveloped and nonenveloped viruses? a) enveloped viruses have their genetic material enclosed by a layer made only of protein.b) nonenveloped viruses have only a phospholipid membrane, while enveloped viruses have two membranes, the other one being a protein capsid.c) enveloped viruses have a phospholipid membrane outside their capsid, whereas nonenveloped viruses do not have a phospholipid membrane.d) both types of viruses have a capsid and phospholipid membrane; but in the nonenveloped virus the genetic material is between these two membranes, while in the enveloped virus the genetic material is inside both membranes.
