The correct answer is antigens and epitope.
An antigen is a substance which triggers an immune response in an organism. This can be either a foreign substance, such as a pathogen, or a specific part of the host organism (in this case this is an autoimmune response). The presence of an antigen activates a specific part of the immune system, called antibody. Each antigen has a specific antibody, which is tailored by the immune system accordingly. More specifically, the antibody has a specific structure, called paratope, which is complementary and binds like a key to a specific structure of the antigen, called epitope.
Answer:
After 1 minute there is 0g of compound A left 2.Then measure 50 grams of unknown compound B into beaker B and stir for one minute. Measure the amount of undissolved solute and record this in Table 1. There is about 15g of compound B left undissolved Control group C hasnt changed Next, we will test the boiling point of each solution. Place each beaker onto a hot plate. 3.When the solution boils, use a thermometer to record the temperature. Record the boiling point for each solution in Table 2. Solution A boils at: 102.8 C Solution B boils at: 108.7 C Solution C (control group) boils at: 100 C Data Table 1 Record the amount of solute left after one minute of stirring. BeakerAmount of Solute at Start (g)Amount of Solute at End (g)Solution with Compound A50 0 Solution with Compound B50 15 Plain water in Beaker C0 (control group) No change
Average =
(124+456+788+343) / 4
= 1711 / 4
= 427.75
= 428
Answer:
When we talk about the inheritance of traits, or the passage of traits from parents to future generations down the line, we are not just talking about the visual (phenotypical) expression of those traits, but also, their underlying explanation, which is the genotype. A genotype is basically how the genes of the parents combine in such a way that the children inherit a set of traits from the parents, and express them phenotypically, or not.
In the case of blood types, we have four phenotypic groups: A, B and O. Each one of these types is characterized by the underlying set of genes that are responsible for what is expressed. While the O blood type presents a genotype ii, which is recessive, the A and B types will have the following genetic patterns: Ia Ia, or, Ia i (characteristic of the O genetic material) for the A type and: Ib Ib, or Ib i, for the B type. When there is a genetic conjugation from parents genetic material, regarding blood type, we would have these sets of genes combining. In most of the possible combinations genetically speaking, we have the recessive i gene appearing, including in the A and B dominant blood types. This means that when crossed, there will always be a chance of at least one offspring presenting the O blood type, even if one of the parents is dominant A, or B.
In answer: it is the fact that all three types present the recessive allele i, typical of the O blood type, that when pairings of genes happen between parents, the genetic characteristic of the O type may present itself in a dominant fashion, instead of the usual recessive pattern.
It is an example of migration. Hope this helps!
