The expression of certain genes at different levels may cause color variation in the butterfly wings.
What is gene expression?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.

If there were 10 bases of thymine in one strand of a model of dna , how many adenine bases would there be in the complementary strand? 0 1 5 10
If there were 10 bases of thymine in one strand of a model of DNA, there would be 10 adenine bases on the complementary strand.
What is DNA pairing?DNA is a biological molecule made up of monomers called nucleotides.
The nucleotides that make up the DNA are as follows:
Adenine ThymineCytosineGuanineIn the DNA molecule, Adenine pairs with Thymine while Guanine pairs with Cytosine. This means that the number of A will equal T while the number of G will equal C.
Therefore, If there were 10 bases of thymine in one strand of a model of DNA, there would be 10 adenine bases on the complementary strand.

Answer:
Hi mate
Explanation:
From Newton law of GRAVITATION
Which sates
Every body in this universe attract every other body with a force that is directly proportional to product of there masses and inversely proportion to square of distance between their center
So from here we came to know that
