Answer:
Earth's outer core is a fluid layer about 2,400 km thick
Explanation:
composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface
Answer:
During transformation and conjugation
Explanation:
Transformation is a process whereby genetic material from another species is introduced into the bacteria through a series of biological steps and manipulation. Conjugation is when the exchange of the genetic material is between bacterial species through a conjugation tube.

RNA nucleotides form complimentary base pairs with DNA bases. Hydrogen and sugar-phosphate bonds form and the mRNA is synthesized.
Explanation:
The process of mRNA formed by DNA is called transcription. The genes coding for the protein is present on DNA as a nitrogenous base or nucleotides.
Transcription takes place inside the nucleus with the assistance of major enzyme RNA polymerase. In transcription 5'to3' single strand of RNA is synthesized which is complementary to the 3'to5' strand of DNA. The sequence of DNA has promoter sites which will be recognized and DNA will unzip to form transcription bubble. Several transcription factors and enzyme will be required to synthesize mRNA.
This mRNA after some modification would become primary transcript and pass on to the cytoplasm where protein synthesis will take place.
All cells have at least one strand of DNA. prokaryotic cells are single celled, plants have a cell wall and vacuoles, animal cells have a centrosome. smooth or: synthesize lipids, metabolized carbohydrates, store calciumrough or: has bound ribosomes, produces proteinsGolgi apparatus: flattened membrane sacs, modifies products of the ER manufacturers macromolecule sorts. lysosomes: membrane sac of hydrolytic enzymes, hydrolyzes proteins, mitochondria: power house of the cell, makes ATP and such chloroplasts: allows photosynthesis to be a thing
