Answer:
confirm the results if you're using edge
Explanation:
The answer would Be A. True
Answer:
The explanation of any natural phenomena requires the proper observation, experiment and research methodology. The experimental design should not violate the ethics and do not cause harm to the living organisms.
The testing of any drug requires the involvement of the experimental group and control group. The experimental group must given the tested drug to known its effect and compared with the control group that will get the placebo understand the psychological effect of the drug.
The correct answer is A) bb
Explanation:
In genetics, an allele is a variation of a gene, which often determines a physical trait. Alleles are classified as dominant if they express even when there are other alleles or as recessive if two copies of the same allele are needed for the gene to express. Moreover, in genetics dominant alleles are represented by uppercase letters while recessive alleles are represented by lowercase letters.
In this context, the allele that is responsible for the brown coat in rabbits is a recessive allele, considering this is represented by lowercase b. This means two copies of the allele are necessary for the rabbit to have a brown coat and therefore the genotype of a brown coat is bb. Also, others such as Bb and BB have the dominant allele related to the black coat, and therefore will lead to rabbits with a black coat.
Huntington's disease is caused by a mutation of the HD gene, which contains extra copies of the nucleotide sequence CAG, which encodes extra copies of the amino acid glutamine into the protein Huntingtin. Mutations in the HTT gene causes Huntington disease. The HTT gene provides instructions for making a protein called huntingtin. This protein appears to play an important role in nerve cells in the brain. The HTT mutation that causes the disease involves a DNA segment known as CAG trinucleotide repeat. In one part of the chain of amino acids in Huntingtin protein there is a long string of amino acid glutamine.
