Lipids serve in the storage of energy, as a structural component of hormones, and also as signalo g molecules
Answer:
C. RNA polymerases.
Explanation:
Bacteria has a primitive type of RNA polymerase while archaeal RNA ploymerase is more advanced and complex than that of bacterial. The structure of archaeal RNA ploymerase has more resemblance with RNA polymerase II of eukaryotes. The RNA polymerase of bacteria requires sigma factor for transcription initiation whereas the RNA ploymerase of archaea requires transcription factors for transcription initiation just like eukaryotes.
Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
Passive transport uses no energy, so an example of that would be diffusion. So your answer would be D, diffusion.
