Answer:
the twitch would be shorter
Explanation:
In muscle cells, the calcium (Ca2+) pump ATPase membrane transport proteins maintain a low cytosolic Ca2+ concentration in order to promote muscle contraction. Muscle relaxation occurs when the sarcoplasmic reticulum reabsorbs Ca2+ through the Ca2+-ATPase protein, thereby reducing intramuscular Ca2+ levels. In muscle contraction, intracellular Ca2+ levels are raised due to the release of Ca2+ from the sarcoplasmic reticulum (SR) via Ca2+-release channels. In consequence, it is expected that a specific drug that speeds up the action of (Ca2+) pump ATPase protein should shorten the contraction-relaxation cycle by increasing the velocity of muscle relaxation.
Eukaryotic cells require mitochondria because the mitochondria is the organelle that converts food (or protein) into energy.

Good luck!
Answer:
An endospore may survive a drought because it is protected by a THICK WALL
Explanation:
An endospore is a structure that is produced by some bacteria. This structure possesses characteristics such as:
a. Endospores have thick walls
b. They are very resistant and resilient to changes in temperature.
c. They are resistant as well to the action or activity of some chemicals.
d. Endospores serves as a means of protection for microorganisms such as Bacteria.
e. Endospores do not reproduce.
f. Endospores can be dormant or Inactive for a very long period of time.
Endospores may survive drought, activity of chemicals, extreme weather conditions, extreme temperatures due to the presence of thick walls in their structure.
