Social forces shape technology both in the form of deliberate social activism and also in unconscious ways. For example, in social activism, large demonstrations against oil pipelines can lead to more rapid development of alternatives to fossil fuels. Somewhat unconsciously, the clogging of cars in tight downtown areas in cities and decreasing parking space gave an impetus to develop new forms of rapid transit like subways and electric articulated buses.
Answer:
450 Å
Explanation:
The amino acids in an α-helix are arranged in a right-handed helical structure where each amino acid residue corresponds to a 100° turn in the helix, and a translation of 1.5 Å (0.15 nm) along the helical axis
Mass of protein= 33.0 kDa
33.0 kDa ×(1000Da/kDa) × ( 1 residue/ 110 Da)
=33.0 ×1000 × 0.0091
= 300 residues
300 residues × (1.5Å /residue)
=450 Å
Answer:
False
Explanation:
It is wrong to claim that when the attraction between particles overcomes their motion, the particles will clump together to boil.
During boiling particles do no clump together, they tend to move apart more rapidly.
- Boiling occurs when the vapor pressure overcomes the ambient atmospheric pressure.
- The hotter part of the boiler close the heat source moves rapidly away because they have become less dense.
- The colder and denser part sinks and this interaction sets up a convection cell.
Answer:
The most likely outcome is that carrier protein dysfunction will increase the gradient which will lead to disruption of cellular metabolism.
