This is the starting molecule for cellular respiration and an important source of energy in cells.
Answer:
Restoration of the diploid condition and the determination of gender.
Explanation
Conception occurs when the male gamete fertilizes the egg and an embryo is formed.
This is event significance in biological developmental science because at this point is when the diploid condition is restored.
When the sperm containing half the number of chromosomes of the father fuses with the egg that contains half the number of chromosomes from the mother to form a diploid embryo.
Secondly, depending on the sperm that fertilized the egg, gender is determined.
I believe it could be B but i am not 100% sure
Answer:
it causes the depolarization of the target cell
Explanation:
Glutamate is an excitatory amino acid neurotransmitter that binds to specific receptors on the surface of target cells and thus causes its depolarization. During glutamate-mediated depolarization, the difference in charge inside and outside the cell is lost due to the entry of sodium and calcium positive ions into the postsynaptic cell (neuron) through specific ion channels. Moreover, glutamate binding also leads to the exit of potassium ions from the cell, thereby resulting in excitation. Through this mechanism, glutamate regulates many signaling pathways, such as those involved in memory, learning, emotions, cognition, motor control, etc.
