Answer:

Explanation:

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.

When the vasomotor center of our brain wishes to increase blood pressure, it increases ____________ signals causing ______.
dlinn [17]

When the vasomotor center of our brain wishes to increase blood pressure, it increases<u> the heart rate signals </u>causing<u> The greater contraction of the heart causes more blood vessels to constrict, increasing the blood vessels' resistance.</u>

By speeding the heartbeat, making the heart beat harder, and constricting some blood vessels, the sympathetic nervous system increases blood pressure. This will enhance the vessels' resistance.

What controls blood pressure by the vasomotor center?

The vasomotor center modifies the tone of the vascular smooth muscle. Both the local and systemic blood pressure are impacted by this. The vasomotor center produces increased sympathetic tone when blood pressure lowers. This causes an increase in blood pressure.

How is blood pressure regulated?

The autonomic nervous system has short-term control over blood pressure (ANS). Baroreceptors are capable of detecting changes in blood pressure. These are situated in the carotid sinus and aortic arch. High arterial pressure causes the blood vessel wall to stretch, activating the baroreceptors.

What systems regulate peripheral resistance in the vasomotor center?

The vasomotor center in the tunica media regulates smooth muscle contraction or vessel tone. Circulating output is impacted by changes in peripheral resistance, pressure, and flow. The majority of these neurons are in charge of causing sympathetic neurons to release the neurotransmitter norepinephrine.

Give reasons why the energy level decrease as you move down a food chain..
avanturin [10]

Answer: Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels. or in materials that the consumer does not digest, or  through movement

Make a list of the things that make a hurricane different from a regular thunderstorm.
Katarina [22]

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.
