Select the size closest to the diameter for actin filament, intermediate filament, and microtubules from the options provided actin filament [answer1]  intermediate filament [answer2]  microtubules [answer3] 

The actin subunits at the plus end of a polymerizing actin filament most likely contain 

Indicate whether each of the following statements regarding skeletal muscle contraction is likely to be true or false. [answer1] When a muscle cell receives a signal from the nervous system, voltage-gated calcium channels open in the T-tubule membrane. [answer2] During muscle contraction, the Z discs move closer together as the myosin heads walk toward the plus ends of the actin filaments. [answer3] When the cytoplasmic calcium concentration increases, a change in the conformation of troponin leads to changes in tropomyosin such that it blocks the binding of myosin heads to the actin filament. [answer4] The changes in voltage across the plasma membrane that occur when a muscle cell receives a signal from the nervous system cause an influx of Ca2+ from the cytoplasm to the sarcoplasmic reticulum, triggering a muscle contraction.

There is an ongoing geographic shift of the American population to the Sun Belt. Which are potential political consequences of this phenomenon?

Which of the statements below about intermediate filaments is true?

Which of the following statement regarding prialt is true?

Normally, when blood glucose level increases (e.g. after a meal), the islet cells in the pancreas secrete insulin. When insulin molecules bind to insulin receptors on the surface of a muscle cell, the receptors become activated, initiating a signaling pathway which eventually results in the increase in the number of passive glucose transporters on the muscle cell surface thus increases the uptake of glucose.  Which one of the following conditions will likely result in diabetes?
