Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Electromagnet. 85% sure on this. Let me know if I'm right.
Answer:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
Starting from the outer part:
•Tunica externa (fibrous layer)
•Tunica media (smooth muscle)
•Tunica intima (endothelial cells layer)
