Answer:
Generally, K+ ions ensures re-polarization of the membrane potential. It always ensures that the neuron returns its resting state, protecting the neurons and ensuring episode of rest before the next action potential.
K+ does this by leaving the axon, making the inner layer more negative. This is resting membrane potential. Because there are many K+ channels for leakages out of the neuronal axons.
Therefore, in this scenario, he neuron will return to its resting membrane potential state which between values -50 to -75mV.
Therefore the value of the potential will be -60mV, or within the range of -50 to -60mV. This is because the neuron is is non- excitable.
Explanation:
Gametes or sex cells (sperm and eggs) contain half the number of chromosomes that exist in autosomal cells; they are haploid. Therefore in the case where the diploid number of chromosomes is 52, the haploid number would be half of that, meaning 52/2 = 26.
Answer:
D. dehydration synthesis
Explanation:
Dehydration means removing water, and synthesis means building or creating something. Therefore, the synthesis of dehydration is defined as removing water to build something. This process occurs by removing a molecule of -OH (hydroxyl group) and a molecule of -H to form H2O or water. This results in the covalent bonding of two monomers (small molecules) to form a polymer (larger molecule).
Dehydration synthesis uses condensation in the process and when this continues for a long period of time, a long and complex chain is formed, such as those of disaccharide or polysaccharides. It is also responsible for storing excess glucose molecules as well as larger polysaccharides such as starch and glycogen.
