Answer:
Ribosome
Explanation:
Ribosomes are mainly made up of ribosomal RNA and ribosomal proteins. Each has two subunits (30S and 60S or prokaryotes) and 40S and 60S in eukaryotes. The smaller unit usually reads the mRNA -with the message from the nucleus -on how to ‘manufacture’ the proteins. The larger subunit actually does the translation by bringing in t_RNAs that carry specific amino acids and then forming peptide bonds between amino acids and ultimately forming polypeptide chains.
A, because plant cells do have membrane-bound nuclei. they have chloroplasts, so that isn't it. Plants don't use oxygen for photosynthesis, but carbon dioxide. The plant walls are made up of cellulose,, not lipids. It must be A.
To carry out cell processes, just like our organs carry out our bodily processes.
The answer
is Up-regulation. One
of the best description of the process of up-regulation is an Increase
the number of surface receptors. Acts as
transcribing factor and binds to DNA, activating a gene. From binding to DNA
before a hormone binds to the receptor.
Answer:
yes because you aren't face to face with anyone your saying it to. If you were, you might not say something like that.
