D. One allele for each gene (Haploid Chromosomes).
My Answer: Mutations produces random changes in an organisms genetic code. Some examples of the changes are: None of the mutations may have a positive, negative nor neutral effect on the organism. A different organism may be produced. Mutations help organisms better, so that they're able to survive, if mutations do that it is more likely that the organism will survive and pass the mutated gene onto the next generation.
Hope I helped! :D
Answer:
Net membrane potential is equal to the difference of positive charge and negative charge existing at the inner and outer side of the cell respectively. Since outer negative charge is higher in concentration, the net membrane potential is negative
Explanation:
The cell membrane potential defined as the net difference of ion concentration existing at the inner and outer side of a cell membrane at nay instance.
When the cell is at the resting potential, the positive potassium ion starts accumulating at the inner surface of the cell membrane as it becomes favors positive potassium ion. This leads to development of negative potential at the outer side of cell membrane by the accumulation of negative ions or charges. Hence, a net negative potential membrane develops.
