When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.

The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).

The varicella virus is a common childhood virus that causes chicken pox. Shingles, a disease also
Ratling [72]

Answer:

The correct option is : It undergoes a lysogenic cycle.

Explanation:

A virus can replicate inside a host cell by two process :

  • Lytic cycle
  • Lysogenic cycle

In the lytic cycle, the viral DNA makes copies of itself and manufactures the viral machinery inside the host cell. Eventually, the host cell bursts causing the release of the viruses. In such a condition the varicella virus would cause chicken pox.

In the lysogenic cycle, the DNA of a virus get incorporated into the DNA of the host. The viral DNA might replicate when conditions become favourable and cause diseases. In such a condition, the varicella virus would cause shingles.

A Cotton shirt takes more time to dry as compared to a synthetic shirt due to absorption of more water by the cotton fiber as compare to other fiber. Cotton absorbs much more water than other synthetic fibers, and attached to the molecules of cotton for longer period of time which means cotton fibers take more time to dry as compared to synthetic fiber which absorb little amount of water and loosely attached to the molecules of fiber.

Part B: Research (11 points) In part B you will be doing some research on desertification.
Goryan [66]
Okay so northern Africa and the Sahara desert is the best example of desertification.
2 ways humans have contributed to that is: 1) pastoral nomadism 2) little to no settlements to increase water supply 

how it impacted the environment: so now the environment there is sandy, only organisms adapted for those extreme environment can live there ex. camel, cactus, etc., 

how it impacted quality of life: quality of life diminished, not enough water to sufficiently feed the populations, people live in extreme poverty, people are moving away, and the climate is very dry and hot, pretty much not a place anyone would want to live
