A biological community of interacting organisms and their physical environment.
The answer is there (3). This is because a mitochondrion has it own DNA called mitochondrial DNA. Therefore the three genetic materials from different parents (mitochondria from donor mother, DNA from biological mother and DNA from biological father) would be present in the baby. Somatic nucleus transfer is the medical procedure used when the biological mother has mitochondria disorder which she would not wish to pass to her offsprings (which are inherited maternally).
Explanation:
The answers are: C D E. Cells are semi-permeable which means it chooses what nutrients and h2o to enter and excretes cell waste into the bloodstream.
The correct answer is d. both excitation and inhibition.
There is a process which is called summation and it refers to the process that determines whether or not an action potential (on postsynaptic neuron) will be generated by the combined effects of excitatory and inhibitory signals (from the presynaptic neurons). Depending on the sum total of inputs, summation may or may not reach the threshold voltage to trigger an action potential (firing of postsynaptic potential).
