Answer and Explanation:
The spread of measles was halted from spreading by developing a vaccine. This is a type of active artificial acquired immunity where the antibodies are formed in the response to administration of dead or attenuated pathogens or toxoids through vaccination. Vaccination protects humans from infections of many diseases. Examples include tuberculosis, poliomyelitis, whooping cough, diphtheria and measles. Measle vaccine is administered 9 months after birth through subcutaneous injection.
B) vinegar
C) lemon juice
D) stomach acid
Carbon
Phosphorus
Hydrogen
Answer:
Explanation:
It is carbon because its used to build macromolecules
Carbon is the element used in organisms as a storage compound, for cell formation, and to build macromolecules due to its ability to form stable bonds with many elements.
Among the elements listed, Carbon is the one most commonly used in organisms as storage compounds, in cell formation, and to build macromolecules. Carbon forms the backbone of complex molecules such as proteins, nucleic acids, carbohydrates, and lipids, all of which are essential for life processes. While elements like Nitrogen, Hydrogen, and Phosphorus also play vital roles in living organisms, it is Carbon's versatility and ability to form stable bonds with many other elements that make it indispensable in the formation and function of macromolecules.

Answer:
The biggest difference is that hurricanes need a warm moist water to keep on going and never forms over land, while thunderstorms can form over land or water. Tornadoes are also associated with cumulonimbus clouds.
Explanation:
A hurricane is a swirling, low-pressure system that develops over the tropics with sustained winds that have reached at least 74 miles per hour.
Warm, moist air near the ocean's surface rises upward, cools, and condenses, forming clouds. With less air than before at the surface, the pressure drops there. Because air tends to move from high to low pressure, moist air from surrounding areas flows inward toward the low-pressure spot, creating winds. This air is warmed by the ocean's heat and the heat released from condensation, so it rises. This starts a process of warm air rising and forming clouds and surrounding air swirling in to take its place. Before long, you have a system of clouds and winds that begins to rotate as a result of the Coriolis effect, a type of force that causes rotational or cyclonic weather systems.
Hurricanes are the most dangerous when there is a big storm surge, which is a wave of seawater that floods communities. Some surges can reach depths of 20 feet and sweep away homes, cars, and even people.
A thunderstorm is produced by a cumulonimbus cloud, or thunderhead, that includes rain showers, lightning, and thunder.
They start when the sun heats the earth's surface and warms the layer of air above it. This warmed air rises and transfers heat to the upper levels of the atmosphere. As the air travels upward, it cools and the water vapor contained within it condenses to form liquid cloud droplets. As air continually travels aloft in this way, the cloud grows upward in the atmosphere, eventually reaching altitudes where the temperature is below freezing. Some of the cloud droplets freeze into ice particles, while others remain "supercooled." When these collide, they pick up electric charges from one another; when enough of those collisions happen, the big buildup of charge discharges, creating lightning.
Thunderstorms are most hazardous when rain decreases visibility, hail falls, lightning strikes or tornadoes develop.
