Biology
1 answer:
Finger [1]3 years ago
8 0
I believe its is because the fossils of these animals looked like living species and they had a connection to the modern. A fossil is any preserved evidence of life from a past geological age, such as the impressions and remains of organisms embedded in stratified rocks. Fossils are created when organisms die, are in cased in dirt and rock, and are slowly replaced by minerals over time.

More blood vessels are stimulated to ______ more than ______ because blood vessels contain more ______ receptors than ______ rec
serg [7]

More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.

<h3>What is Vasoconstriction?</h3>

This is the process which involves the narrowing of the blood vessels through their muscle wall.

They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

Select the correct answer. An object is acted upon by a force of 22 newtons to the right and a force of 13 newtons to the left.
lana [24]

Answer:The net force is the sum of all the forces acted upon an object. The direction of force depends on which side you are taking as a positive and negative force. If the force of 22 newtons is positive and the force of 13 newtons is negative, they are actng on the object on different directions, thus in order to get the net force, we just sum them up.

newtons

The net force is +9 Newtons.

Animals with a three-chambered heart would include:_______
Setler79 [48]

Animals with a three-chambered heart would include Amphibians.

  • Amphibians have three-chambered which comprises of two Atria and one ventricle. Examples of Amphibians include Frog, Toads, Salamanders.
  • In Amphibians heart blood from the single ventricle travels to the lungs, skin, and body, where it is oxygenated. Before being pumped out of the heart, deoxygenated and oxygenated blood are mixed in the ventricle.
  • This is because the Amphibians have low rate of metabolism and thus requires less oxygen for their metabolism.
  • As a result heart's load to deliver oxygenated blood to body is lowered.

Thus, from the above pointers we can conclude that only Amphibians from the option have three-chambered heart.

In the tonicity of red blood cells activity, why were you unable to read the lab manual through the tubes containing hypertonic
kap26 [50]
The reason why we were unable to read the lab manual through the tubes containing isotonic and hypertonic solution is  because the cells in those solutions remained intact, causing the solutions to be opaque, in the tonicity of red blood cells activity. The reason why we can't read the lab manual is because the cells in the solutions remained intact.
