The answer is C. Alleles form your genetic makup :)
please mark as brainliest! thank you!
It is strengthened by data which is always contradictory.
Definitely C) she did not have enough information to prove her theory to be right.
Fossils give Scientists look into past life. A dinosaur that mixes together a reptile and a bird helps scientists understand present day reptiles & birds. Animal Ancestry helps Scientists discover what ancestors of present day animals are. example: a dinosaur and an alligator. DNA sequences help with this. By matching together the strands of DNA from these fossils can help scientists match together the strands of DNA sequences For example the gene for a protein found in a horse will overlap in sequence fairly well with the protein gene from a cow but will not match very well with a worm.
The answer would be A packing becomes less tight. The double bounds create kinks in the chain making it harder for the chains to back tightly
