A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />
Those chemicals absorbs heat from the surrounding while reacting
B. mitochondria and nucleus
two steps of expression of a gene in their correct chronological order are Transcription then translation.(option a)
The process by which information from a gene is used in the synthesis of a functional gene product that enables it to produce protein or non-coding RNA end products and ultimately affect a phenotype as the final effect is known as gene expression.
It comprises two significant stages: translation and transcription, Gene expression is made up of transcription and translation working together to form a polypeptide.
- The production of RNA from DNA is known as transcription. The enzyme RNA polymerase acts as the catalytic agent.
- The process by which a messenger RNA's genetic code is decoded to produce a particular polypeptide chain is known as translation. A particular amino acid is specified in each genetic code.
