Solution Steps

Step 1: Identify the labels

Review the labels provided:

  1. All calcium ions from sarcoplasmic reticulum
  2. Cells have single nucleus
  3. Calcium ions from extracellular fluid and sarcoplasmic reticulum
  4. Voluntarily controlled
  5. Functions to pump blood
  6. Cells have multiple nuclei
Step 2: Determine the characteristics of cardiac muscle

Cardiac muscle characteristics:

  • Cells have a single nucleus
  • Calcium ions from extracellular fluid and sarcoplasmic reticulum
  • Functions to pump blood
Step 3: Determine the characteristics of skeletal muscle

Skeletal muscle characteristics:

  • All calcium ions from sarcoplasmic reticulum
  • Voluntarily controlled
  • Cells have multiple nuclei

Final Answer

  • Cardiac muscle (2/2):

    • Cells have single nucleus
    • Functions to pump blood

  • Skeletal muscle (2/2):

    • All calcium ions from sarcoplasmic reticulum
    • Voluntarily controlled

in a building rented strictly to whites, in a section of the basement that was shut off and forgotten during the nineteenth century, which I discovered when I was trying to escape in the night from Ras the Destroyer. But that's getting too far ahead of the story, almost to the end, although the end is in the beginning and lies far ahead. The point now is that I found a home-or a hole in the ground, as you will. Now don't jump to the conclusion that because I call my home a "hole" it is damp and cold like a grave; there are cold holes and warm holes. Mine is a warm hole. And remember, a bear retires to his hole for the winter and lives until spring; then he comes strolling out like the Easter chick breaking from its shell. I say all this to assure you that it is incorrect to assume that, because I'm invisible and live in a hole, I am dead. I am neither dead nor in a state of suspended animation. Call me Jack-the-Bear, for I am in a state of hibernation. My hole is warm and full of light. Yes, full of light. I doubt if there is a brighter spot in all New York than this hole of mine, and I do not exclude Broadway. Or the Empire State Building on a photographer's dream night. But that is taking advantage of you. Those two spots are among the darkest of our whole civilization-pardon me, our whole culture (an important distinction, I've heard)-which might sound like a hoax, or a contradiction, but that (by contradiction, I mean) is how the world moves: Not like an arrow, but a boomerang. (Beware of those who speak of the spiral of history; they are preparing a boomerang. Keep a steel helmet handy.) I know; I have been boomeranged across my head so much that I now can see the darkness of lightness. And I love light. Perhaps you'll think it strange that an invisible man should need light, desire light, love light. But maybe it is exactly because I am invisible. Light confirms my reality, gives birth to my form.
