Simple Diffusion Across the Cell (Plasma) Membrane. The structure of the lipid bi-layer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
No, because its genes are still the same. To evolvewould mean that the frog had one set of genes as a tadpole, then a different set as an adult. It just doesn't work that way. The genes are the same.
Let’s get one thing straight electrons mean negative so I’m going to say very negative cause it spends more time around hydrogen atoms
Answer: b. removal of introns from mRNA
The process by which Ribosomes attached to ER or lying freely in the Cytoplasm synthesize proteins from the transcribed mRNA of the DNA is called Translation.
Explanation:
It is made up of three stages;
1. INITIATION;Options C mRNA binding to the ribosome
2. ELONGATION ;Option D joining large and small ribosomal subunits
3, TERMINATION;Option E chain termination at a stop codon
However, Introns are non coding region of RNA base sequence transcribed from the DNA, or sections of DNA encoding the RNA. It is an unwanted part which must be sliced out before translation. Therefore it is not a relevant steps of translation, and hence Option B is the wrong answer.
Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.
I think the answer is A or D
