Answer:
phototropism
Explanation:
phototropism is the plant responding to external stimuli, in this case the sun.
Answer:
Huntington disease is a dominant autosomic disease so it presents either in heterozygosity (Aa) or in homofzigosity (AA)
observing the pedigree, the two parents have the Aa genotype so by making the punnet's square we have as possible genotypes: AA, Aa, Aa, aa. So the chance to get the disease is 25%
1,560,000 milliseconds is 26 minutes and 26 minutes is about .43 hr
so the second one is the correct answer
Answer:
<h2>C) The height of the plant</h2>
Explanation:
Dependent variable - is the variable that can not be manipulated and the one that's being observed.

The expression of certain genes at different levels may cause color variation in the butterfly wings.
<h3>What is gene expression?</h3>
Gene expression is the cellular process associated with the transcription of certain genes in particular cell types.
In this case, the trait color in butterfly wings is associated with the differential expression of certain genes during development.
The variation in color may be due to the expression of different alleles in butterflies or the same allele at different levels.
