Cowpox and Smallpox are very similar diseases. When cowpox is injected into the body in a form of a vaccine, a weakened germ cell of the disease enters the body. Since it is weakened, the body is able to easily fight it off by sending antibodies. After the antibodies kill off the germ cell, B memory cells hold the information of the threat, so if in the future, when the host contracts the virus/disease again, the body is able to counteract it faster than it did the first time around. So since Cowpox and Smallpox are very similar, when a person is first injected with the Cowpox vaccine, the B memory cell remembers information about Cowpox. Then when the host contracts Smallpox, the body sees Smallpox as the same thing as Cowpox, so the body can fight off Smallpox quickly, and thus preventing Smallpox.
Answer:
7 ten thousands + 3 thousands + 2 hundreds + 5 tens + 0 ones
Explanation:
We use the classification system when grouping organisms, which are very diverse. The sub-group with the least amount of diversity is the species. The measure of diversity in this classification will of the variation in genome and physical characteristics. The species have a slight variation in the genome and phenotype compared to the amount of variation in a genus, where related species are clubbed together. The amount of diversity increases from the nodes of a classification tree to its root or parent (kingdom).
Answer:
<em>The correct option is D) increase production while reducing environmental impacts.</em>
Explanation:
Although the usage of GM crops has its own benefits, yet there are certain problems related to GM crops which cannot be ignored. One such problem is that by producing GM crops we are reducing the genetic diversity of certain crops. Such cases can be disastrous as there will be no genetic diversity present if disastrous conditions such as a disease occur.
However, GM crops are beneficial as they can increase the production of a crop with enhanced characteristics.
Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.
