When the body senses a state of hypoperfusion, the sympathetic nervous system releases epinephrine, the effects of which?
lutik1710 [3]
Heart rate is controlled by the two branches of the autonomic (involuntary) nervous system. The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). The sympathetic nervous system (SNS) releases the hormones (catecholamines - epinephrine and norepinephrine) to accelerate the heart rate. The parasympathetic nervous system (PNS) releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate.

During embryonic development, the vertebral column is replaced by the notochord.
Reptile [31]

Hello! The answer is false.

It is actually the opposite. The notochord is a primitive axial skeleton, and in humans, it disappears. It eventually becomes part of the vertebral column, which is the backbone that we have today.

Hope this helps!

What factors go into calculating an ecological footprint
zzz [600]
<h2>Ecological Footprint</h2>

Explanation:

  • <em>The Ecological Footprint</em> of an individual is determined by including the entirety of individuals' requests that vie for organically gainful space, for example, cropland to develop potatoes or cotton, or <em>backwoods to create timber or to sequester carbon dioxide outflows.  </em>
  • The national normal or per capita Ecological Footprint of utilization is equivalent to a <em>nation's Ecological Footprint of utilization isolated by its populace.  </em>
  • As indicated by the Global Footprint Network, the Ecological Footprint for the normal American is 8.6 gha, more than twofold Brazil's normal of 3.1 gha and Mexico's normal of 2.6 gha.  Check The month to month service bills.
  1. <em>Increase your kilowatt hours by 1.85. For instance, 67 hrs X 1.85 = 123.95 lbs of CO2.  </em>
  2. <em>Increase your flammable gas use (therms) by 13.466. For instance, 19 therms X 13.466 = 255.854 lbs of CO2.  </em>
  3. <em>Increase gallons or propane utilized by 13.  </em>
  4. <em>Increase gallons of fuel utilized by 22.</em>

Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.
