Answer: Some stunts and activities can be dangerous to be performed and must be done with utmost precautions.
Explanation:
The activities such as sky diving, stunt performing and race car driving can be risky for mental and physical health. These activities can cause mental or physical trauma can even lead to death but some people still engage in such activities because they want to do some daring and they want to overcome their fear and want to set up a benchmark in the society. Such activities are potentially responsible for boosting courage, confidence, and strength to overcome fear.
Migrating to a location that suits them
Answer:
organisms lacking gas filled spaces like lungs / swim bladders
Answer:
The amino acid sequence resulting from the DNA code TACGGGGCGATTGG is Methionine (starting codon), proline, arginine and STOP codon.
Explanation:
DNA is the molecule that contains four nitrogenous bases in its structure, whose sequence determines the order and amount of amino acids that a protein will have.
For protein synthesis to occur, DNA must be transcribed into mRNA, which leaves the cell nucleus for translation to occur in the ribosomes. The sequence of nitrogenous bases of the mRNA is organized into triplets or codons, which determine:
- <em>Initiation of protein synthesis.
</em>
- <em>Sequence and number of amino acids that a protein contains.
</em>
- <em>End or stop of protein synthesis.
</em>
For the given DNA sequence, the corresponding amino acids are:
- DNA TACGGGGCGATTGG
- mRNA AUGCCCCGCUAACC
- Codons AUG-CCC-CGC-UAA-CC
- Amino acids Met - Pro - Arg - STOP
The last two cytosine molecules are not translated because they do not form a codon and because the previous codon completed protein synthesis.
Answer:
The balance form of the equation is given below.
Pb(NO3)2+2KI ——-> 2KNO3 + PbI2
Explanation:
In this equation lead nitrate and potassium iodide are reactants while potassium nitrate and lead iodide are the products. In the unbalanced form of equation, two molecule of iodine are formed in the product whereas there is only one molecule of iodine is present in the reactant. So for balancing this, 2 value is put in front of potassium iodide but by putting 2, potassium is also double in the reactant so 2 is also placed in front of potassium nitrate in the product and the equation is balanced.
