The correct answer is C. The right side of the heart delivers deoxygenated blood (from vena cava) to the lungs (via pulmonary artery)
<span>The answer is letter B. The formation of the three geminal layers and the primitive gut. The formation of gastrula starts when the cells starts folding in blastula slowly forming into a blastopore, that results to a double layer cup cell, forming the geminal layers and the primitive gut </span>
The correct answer is: D) Binding of the neurotransmitter causes chemically gated sodium channels to open in the motor end plate (junctional folds of the sarcolemma) and sodium enters the cell.
The motor neuron cell is connected to muscle cell via synaptic cleft, where neurotransmitter is released. The muscle side of this synapse is called motor end plate. Released neurotransmitter is acetylcholine and it binds to its receptor (ACh receptor) on the motor end plate. As it binds, ion channels open, and Na+ gets into the muscle cell. This event reduces the voltage difference between the inside and outside of the cell and causes depolarization which creates a wave through the entire muscle cell (its membrane-sarcolema). As a consequence, Ca2+ is released from the sarcoplasmic reticulum which will cause the contraction of the muscle cell.
Answer:
E contain primarily carbon,hydrogen,and oxygen
Explanation:
Answer:
Yes , it is possible to make sequence of another nucleotide.
Explanation:
An adenine on one strand is always paired with a thymine on the other strand, and a guanine is always paired with a cytosine . If the sequence of nucleotides on one strand is known, the sequence of the other strand will be automatically known as well.
I hope this helps you
