Answer:
Neutron star
Explanation:
neutron star is formed from the collapsed core of a very giant star, that has a total mass that range from 10 and 25 possibly. They stars are the smallest and densest stellar objects except from black holes and hypothetical white holes, quark stars, and strange stars.
They are produced from the supernova explosion of big star and gravitational collapse that presses the core past white dwarf star density to that of atomic nuclei.
5. The answer is D. Non-renewable resources lay be cheap, but they release harmful carbon dioxide, which pollutes the environment. And eventually, they will run out. They are, as the name suggests, non-renewable.
6. The answer is A. Renewable resources are harder and more expensive to harvest, but they are unlimited and cause little to no harm to the environment, depending what resource you are using.
7. The answer is A. Particular renewable resources ( i.e sunlight or geothermal energy) are unreliable and can only be found in the right places under the right conditions (i.e on a sunny day or a geyser). They're also more expensive since they're harder to access/convert into electricity.
8. The correct answers are D and E.
Technology helps us predict future problems and solve them before they even happen, and things like solar panels and dams help us use alternative energy, which is much better for the environment than things like coal or oil.
9. The correct answers are A and D. Biodiesel is made from various oils and animal fats (unwanted waste), and it is renewable.
10. The correct answer is A. Biodiesel is more expensive to make than regular diesel, and more facilities would have to be built.
Good luck on your assignment!
Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).
