Protein function is directly related to the structure of that protein. A protein's specific shape determines its function. if the structure of the protein is altered because of a change in the structure of the amino acids, the protein becomes denatured and does not perform its function as expected.
For the first one, electrons travel around the nucleus in fixed energy levels with varying energies.
Second one, protons, neutrons, and electrons have a mass, but electrons have far less mass
Third one, cations and protons
Fourth, not sure.
Answer:
Plants photosynthesize <em>only in the light but respire in light and dark</em>.
Explanation:
The reactions of photosynthesis occur only during the day. This is because sunlight is used for converting water and carbon dioxide into oxygen and glucose in the presence of sunlight. The light of the sun s the energy force which drives this reaction.
However, the reactions of respiration continue at day and night. The reactions of respiration do not require light energy from the sun.
<span> You need to use this formula to solve this exercise: P(t)=Ae^(k.t)
P(t) is the p</span><span>opulation of bacteria
A is the number of bacteria at the beginning of the experiment: 71
K is the growth rate
20 min= 1/3 hours
P(0)=71
P(1/3)= 71 ⇔ P= 71 x 2 ⇔142
142= 71 x e^k/3

ln 2 = k/3
3ln 2=k
ln(2³)=k
</span>k=ln8
Answer:
B
Explanation:
The 3'-end of the reverse primer (3'-TTGGCCAATGG---5') is complementary to the forward primer (5'---AACCGGTTACC-3') and thus reduces the ability of the primers to bind to the targeted DNA sequence. There is possibility of hairpin loop formation or primer dimmers formation
