Answer:
3) B
4) A
5) B
Explanation:
3) Sun heats up the air of a particular region due to which the air heated rises up ( as hot air is lighter than cool air ). When the hot sir rises , the cool air from other region comes there & like this wind blow.
4) A toaster uses electricity to produce heat in order to toast bread So here the electric energy is converted to thermal energy.
5) Windmills , Hydroelectricity dams & Ethanol plants have turbines & turbines do have a generator which is to be rotated . When the generator is rotated , electricity is generated.
Yes, It indeed is inside a cell's nuculeus. You are correct
Answer:
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
Explanation:
pre-mRNA, mRNA, rRNA, RNA primers, snRNA
a. transcription/RNA processing
: pre-mRNA, snRNA
b. translation
: mRNA, rRNA,
c. not used in protein synthesis: RNA primers
The pre mRNA the product after transcription from the DNA is processed eg by addition of poly A tail, splicing etc before undergoing the process of translation, the snRNA also help in performing this function. In translation, the mRNA is trnslated to proteiin in the ribosomes which is also made up of rRNA and proteins. RNA primers is not needed in any of these two, only i DNA replication as the DNA polymerase is uable to begin the synthesis of adding nucleotides to a DNA strand.
The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.
