Answer:
Why are synovial joints freely movable?
Diarthroses are freely movable articulations. ... The bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of joint ends of bone with a smooth, slippery surface that does not bind them together. This articular cartilage functions to absorb shock and reduce friction during movement.

please give me brainly got my answer from G00GLE so of course its correct hope i helped!!!
Answer:
cAMP dependent pathway is important for processing of life.
Explanation:
cAMP pathway is also called as adenynyl cyclase pathway.
This mechanism requires different steps like-
- G protein coupled receptor is a integral protein that is activated by different external stimuli which binds with the specific ligand.
- Extracellular ligand causes activation of GPCR which in turn is responsible for conformational change in the receptor and allows it to bind with the intracellular heterotrimeric G protein complex.
- The Gα stimulate G protein complex to exchange GDP for GTP and then the complex is released.
- Activated Gα binds with adenylate cyclase and catalyzes ATP to form cyclic AMP.
- Activation of cAMP leads to the activation of nucleotide gated ion channel, and PKa(Protein kinase A) which is also called as cAMP dependent enzyme.
- Once, PKA is activated,it causes phospholylation of other proteins like AMPA receptor,transcription factors which regulate gene expression, and convert glycogen into glucose.
You use the mRNA to make amino acids.
I believe that the answer is (A) , cause if their hetero then it could be a 50/50 chance so if its not (A) then it might be (D)
forgive me if i am wrong, have a nice day! :)
