The embryonic development of animals suggests an order of relation between humans and other animals; some animals being more closely related to humans than the others. Compare the embryos of the salamander, chicken, and monkey to that of the human (top image).

What statements about the embryos are true? Check all that apply.

All four animals begin as fertilized eggs.
The salamander and the chicken do not have an umbilical cord.
Only the fish has ancestral gill slits.
All four have identical limb buds.
Only the chicken will develop a shell breaker.

fabric is silk wool ext. paper isnt

explanation:

u cant make fabric out of paper cause paper comes from wood while fabric comes from animals

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
