Answer and Explanation:
1. Amino-acid sequence is the primary structure of a protein
2. Alpha helices, beta sheets and coiled coils refers to the protein folding and they represent the secondary structure of a protein
3. Protein ensemble formed by alpha helices, beta sheets and coiled coils represent the tertiary structure of a protein
4. Macromolecules with multiple polypeptides form globular or fibrous protein structures (quaternary structure)
Answer: Increase the depth of ventilation.
In high altitude, the oxygen pressure will be much lower that makes the gas exchange rate is lower and decrease the oxygen delivery to <span>the tissue.</span> To counter this, the mouse will increase its depth of ventilation so there is more air inside the lungs for every inspiration.
Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
Answer:
The volume of a pair of dice could be gotten by measuring the
sides and calculating it via length/width/height. A second manner
would be displacement, where the dice are placed in a liquid with a
known density, and the mass of the liquid displaced is used to
determine volume.
