Answer:
it condenses the DNA so that it can fit inside the cell.
Explanation:
Supercoiling is a level of genome packaging and is important for the packaging of the DNA which is about 2m in length inside a nucleus that is about 6microm. Supercoiling refers to the over (positive supercoiling) or under winding (negative supercoiling) of a DNA strand, and is an expression of the strain on that strand. Supercoiling is in compacting DNA, and also allows for the regulation of access of transcriptional machinery and other biological activities to the DNA and in turn gene expression. Certain enzymes such as topoisomerases are able to change DNA topology to facilitate access of DNA replication or transcription.
Answer:
For the given case, one would fence off some part of land with antelope and the plants they feed on and similarly fence off some other part of land with no antelope. After that comparative analysis is done with the two experimental plots to check that whether the herds of African antelope influences the abundance of plants they consume.

Answer:
The correct answers are "heterozygous", and "homozygous dominant".
Explanation:
Galactosemia is a condition where people are not able to process the sugar galactose. People with this condition have one gene mutated, which does not allow the proper synthesis of the enzyme that breaks down galactose. Galactosemia is inherited as an autosomal recessive genetic condition, therefore, only children that are homozygous recessive develop the condition. Children that are heterozygous or homozygous dominant, will not develop galactosemia.
