<span>A property of t cells, but not b cells, is their </span>ability to form cells that directly kill virus-infected host cells.
The plasma membrane of the enveloped alga cell serves as the source of the apicoplast's second outermost membrane.
<h3>Where did all chloroplasts come from?</h3>
Chloroplasts were first established in eukaryotes through an endosymbiotic relationship with a cyanobacterium; they later spread through the evolution of eukaryotic hosts and the subsequent engulfment of eukaryotic algae by formerly nonphotosynthetic eukaryotes.
<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>
Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.

Answer:
Double-stranded RNA (dsRNA) are defined as the RNA having two complementary strands, same as DNA in all cells, in the replacement of thymine by uracil.
Double-stranded RNA derived from an intron are able to induce RNA interference and found to encode microRNAs (miRNAs), which are responsible for gene silencing mediated by RNA through RNA interference (RNAi) pathways.
miRNAs, which are small single-stranded regulatory RNAs that interferes with intracellular mRNAs (messenger RNAs) containing either complete or partial complementarity, are used to design new cancer therapies against polymorphism and viral mutation.
The correct answer is the letter C. acids.
An acid contains hydrogen that has the capability of donating proton (+) in a solution. So when an acid is dissolve in a solution, it releases hydogen ions.
