There are five characteristics of Muscles; namely Responsiveness, Conductivity, Contractibility, Extensibility and elasticity.
Assigning each example to the universal muscle characteristic being described;
Conductivity; (electrically stimulating a muscle) Local electrical change triggers a wave of excitation that travels along the muscle fiber.
Contractibility; Shortens when stimulated
Elasticity; Returns to its original resting length after being stretched,
Extensibility; capable of being stretched between contractions.
Responsiveness; to chemical signals, stretch, and electrical changes across the plasma membrane.
Answer:
A. The atom is mostly empty space.
B. Electron orbit around the center of the atom.
C. The atom's positive charge is located in the atom's nucleus.
Explanation:
Rutherford is a chemist which performnan experiment in order to see what is present inside the atom. He bombarded radiation from a source on an atom. He observed that most of the radiation pass through the atom so he concluded that the atom has mostly empty while some comes back which means that a heavy particles are present in the nucleus.
C. The combination of high winds and flood waters.
Hope this helps you! :)
Answer:
Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.
Explanation:
You're making a hypothesis for the Redi and Pasteur experiments?
Redi's experiment regarded maggots in jars with meat. And Pasteur's experiments involved nutrient broth culturing bacteria or not.
So:
If the jars containing meat are covered, then maggots will not grow or hatch inside because life cannot form without life and the covers would block flies.
If the nutrient broth is boiled before being sealed, then the uncovered broth will breed bacteria but the sealed broth will not because the bacteria have all been killed from heat and cannot reproduce.
or something along those lines. Eh.
