Answer:
Promoter 2
Explanation:
Promoter 2 is the best choice because the resistance gene will only be expressed in the leaves of the corn plant. Promoter 3 only expresses genes in the corn roots, so the toxin would not be available in the leaves for the pest to eat. Promoters 1 and 4 would express the resistance gene in the leaves of the corn plant, but the toxins would be expressed in the corn cobs as well, which may then be fed to livestock.
Answer:
1) Firstly, lets sort out the alleles for the dominant and recessive characteristics. The dominant brown allele will be written as B and the recessive red hair allele will be written as b.
2) Lets sort out the genotype of the parents. The parent having homozygous brown coloured hair will carry the alleles BB. The parent carrying the heterozygous brown coloured hair will carry the alleles Bb.
3) The punnet square from these parents will be drawn as follows:
B b
B BB Bb
B BB Bb
4) Now, lets predict the phenotype of the offsprings. The results from the punnet square show that all of the offsprings will have brown coloured hair.
5) The genotype for the children will have 50% chance to be homozygous brown (BB) and 50% chance to be heterozygous brown (Bb).
Answer:
ATP
Explanation:
Adenosine triphosphate (ATP). This nucleotide is very essential in the cell. It is the main source of energy in a cell and is utilized in many biological processes by the cell.
A vaccine is a substance that supports the body to produce antibodies and offer immunity in contradiction of a disease. A live attenuated vaccine comprises a version of the living microbe that has been destabilized because they are still alive this is the closest thing to an actual infection and will habitually lead the body to have a lifelong immunity after only one or two doses. A killed vaccine is created by killing the illness with chemicals, heat or radiation in which these vaccines are harmless but rouse a weaker immune reaction.
