Shrike Bird- Catches bugs and sticks them on thorns to impress potential mates
Birds Beaks- Birds have adapted to eat many different foods, their beaks show what kind of food they eat
Answer:
2. tRNAQ binds the A site of the ribosome.
1. The polypeptide is transferred to tRNAQ.
4. The ribosome shifts, with tRNAQ still bound.
3. tRNAQ binds the P site of the ribosome.
4. The ribosome shifts, with tRNAQ still bound.
5. tRNAQ binds the E site of the ribosome.
Explanation:
tRNAQ first lands on the A site of the ribosome. It carries an amino acid according to the exposed codon on A site. A bond is formed between the amino acid of A and P site such that the polypeptide is transferred to tRNAQ. The ribosome shifts now and tRNA Q moves to P site from A site while still bound to mRNA. Another tRNA enters the A site and the above process is repeated which finally transfers the polypeptide chain from tRNAQ to new tRNA. tRNAQ has no attached polypeptide now and is ready to leave the translation complex. The ribosome shifts again with the tRNAQ still bound to mRNA. tRNAQ enters the E site from P site and finally leaves the translation complex by exiting the E site.
Answer: Rougher Surfaces
Explanation: Rougher surfaces have more friction between them than smoother surfaces. The rougher surface of the soles of the shoes causes more friction and slows you down.
Answer:water moves out of the cell and it undergoes plasmolysis
Explanation:algae cells are plant cell.they have chlorophyll, carotenoids and phycobillins as their photosynthetic pigments.
They also possesses cellulose cell walls .
During osmosis,water moves from a region of low concentration of solute to a region of high concentration of solute.
In the above case,both the algae cell and it's surrounding solution has the same concentration of solute . however as solute is added to the solution it becomes more concentrated and water moves out of the algae cell .As the cell continues to lose water,the cell body pulls away from the cell wall causing a phenomenon called plasmolysis.
