Answer:
The electric field on the surface of a conductor is perpendicular to its surface.
Explanation:
A conductor is a material that has the ability to transport electric charge through it.
Inside such a conductor that is in equilibrium, the electric field is zero, so that the charge accumulates on the surface of the conductor.
The electric field on the surface of a conductor is perpendicular to its surface.
This external electric field on the surface of the condutor can be calculated by Gauss's law, which establishes the equivalence of the flow across a surface with the net charge inside the conductor divided by the permittivity in the vacuum.
Answer:
A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...
Explanation:
Involved in the transport of proteins with the first signal sequence but not the second one.
For diastolic, I know the average is 120/80. Not sure about systolic
<span>The distinct evidence of climate change in the O’Higgins glacier is proven by the measurement of the area that it covers. About 11.5 kilometers of glacier land has melted within the twentieth century. Satellite images reveal the retreat of glaciers where they compared early 1900s images from the present.

And: Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes.
