Im going to go with C only because most dont make sense.
Answer:
Having a true coelom as a body cavity.
Explanation:
Coelomate contain tissues derived from mesoderm, whereas pseudocoelomates have no such tissue. have a gut that lacks suspension within the body cavity, whereas pseudocoelomates have mesenteries that hold the digestive system in place. Have a body cavity completely lined by mesodermal tissue, whereas pseudocoelomates do not.
If the Calvin cycle slows down, THE RATE OF OXYGEN PRODUCTION IN PS II WILL BE REDUCED.
This is because, the light reaction depends on the dark reaction to occur. If the Calvin cycle slows down, the light cycle will have less ADP and NADP+ to work with and this will slow down the production rate of the photosynthetic reaction.
F508
it changes the composition of the DNADNA is chiefly responsible for storing and transferring genetic information whereas RNA acts as a messenger between DNA and ribosomes during the process of protein synthesis and directly codes for amino acids.
DNA is double stranded while RNA is single stranded.
DNA has thymine in its structure but RNA does not. Instead in place of thymine it has uracil.
An mRNA template and tRNA work together in a ribosome to make protein from amino acids.
hope this helps!
