Their population will decrease while that of orange-winged butterflies will increase. Therefore the allelic frequency for blue colored wings will be eventually eliminated from the population.
This is because the blue-winged butterflies will be predated more because they are more conspicuous. Most will not produce before they are predated on hence reducing their numbers. The next generations will have more and more of orange-winged butterflies until the blue-winged butterflies no longer exist in the population.
The main difference between a sheep heart and a frog heart is that sheep have a
four-chambered heart and frog
three-chambered heart.
<span>The heart of an amphibian, such as a frog, has three chambers, one ventricle and two atria. Blood from the ventricle travels to the lungs and skin where respiration occurs and where the blood becomes oxygenated. From the ventricle, blood also travels to the rest of the body where it becomes deoxygenated. In the ventricle, deoxygenated and oxygenated blood are mixed before being pumped out of the heart. </span>
<span>On the other hand, mammals (including sheep) have two atria and two completely divided ventricles. The left side of the heart pumps and receives only oxygenated blood while the right side of the heart pumps and receives only deoxygenated blood, meaning that their systemic and pulmonary systems are separated. The separation of these two systems enables mammals to
deliver more oxygen to their tissues (because there is no mixing of oxygenated and deoxygenated blood)<span>. Thus, mammals' heart is more efficient.</span></span>
Cochlear duct(Scala media)
the portion of membranous labyrinth within the cochlea filled with fluid that vibrates when sound waves are transmitted by the stapes. (between scala vestibuli and scala tympani)
Answer:
hybridation. Puggle is a combination of two different species of dogs and the process of combining two different species to produce a new species is known as hybridation.
Answer:
Troponin and calcium ions.
Explanation:
Troponin is a component of thin filament along with tropomyosin and actin. It is a protein complex to which calcium binds and start the production of muscular force.
Calcium also playing a very important role in muscle contractions, it binds with troponin and helping to move tropomyosin.
When calcium ion attached to troponin, then conformational changes occurs in troponin shape and moves which allow tropomyosin going away from its inhibitory position from the myosin-binding sites on actin. After this, the energized myosin head starts binding to the actin molecules and starts the cross bridge cycle, which helping in shortening the muscle's fiber.
