Answer:
4. The A allele is dominant to the a allele.
Explanation:
In genetics, the dominant allele which is expressed when present in single or two copies is always written with an upper case letter. The corresponding allele whose expression is prevented in the presence of the dominant allele is written in the "lower case letter". This is called recessive allele. In the given genotype, one copy of "A" and one copy of "a" is present. This means that the allele written with upper case letter "A" is dominant over the allele "a". Nothing can be said about the genetic trait regulated by these two alleles of a gene.
Answer:
Trix cereal contains simple carbohydrates, which differ from complex carbohydrates in that they are easier for the body to break down. However, this is not necessarily a good thing. Simple carbohydrates are often too easy for the body to break down, resulting in a boost of energy, then a sugar crash. Try something like an apple or a banana instead, for a good source of complex carbs.
Ion transport or active transport depending on which situation you have.
Answer:
He extracted and observed DNA from white blood cells.
Explanation:
Friedrich Miescher, who is a Swedish Botanist, is the scientist who isolated for the first time. In 1869, Miescher isolated a chemical he called NUCLEIN, which is called Nucleic acid now.
He discovered this so called "NUCLEIN" substance from the nuclei of white blood cells. Nucleic acids are the DNA and RNA we know today, hence, Miescher's discovery was significant to the genetic code as he even agitated for the inclusion of his discovery into inheritance.
