The number of trophic level in food chain is limited because at each trophic level a large amount of energy is being utilized for the maintenance of organism and lost as heat.
Explanation:
Answer:
The mice died
Explanation:
In Griffith's experiment, two strains of the same bacteria were used. S strain was smooth because it had a polysaccharide coat. This coat also made it virulent because mouse immune system was not able to destroy it and ultimately the mice died. R strain was rough because it did not have the coat and thus was harmless to mice.
When Griffith injected mice with dead S bacteria and living R bacteria together, the mice died. Live R bacteria had taken up the genetic material or as Griffith called "transforming principle" from the dead S bacteria and transformed into S bacteria. So live S bacteria were present again and they killed the mice.
Answer: They receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA).
Explanation: This mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein.
The answer is protein synthesis......
b would be the answer sorry if its wrong.
