Afluid-filled sac that decreases friction where a tendon rubs against a bone near a synovial joint is called a/an

The correct answer will be -Bursae

Explanation:

A bursa is a thin, fluid-filled connective tissue sac present around the synovial joints where it helps reduces the fiction caused by the rubbing of the bones, ligaments and tendons.  The bursae are classified on the basis of their presence in the human body.

The Bursae reduce the friction by between two structures of the skeletal system by physically separating the adjacent structures due to the presence of the fluid.

Thus, Bursae is the correct answer.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

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.
