It would probably be A because it splits off into two lines but I’m not for sure
Explanation:
the allele for unattached earlobes is dominant over the allele for attached earlobes. In a population if “500 individuals”, 25 percent show the recessive phenotype. How many individuals would you expect to be heterozygous for this trait?
possible answers:
• 75
•125
•200
•25
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.
ANSWER: CANCER DEVELOPMENT
EXPLANATION:
Tumor suppressor genes (TSGs) are genes that regulates the cell cycle of a cell (i.e the cell division and replication). In other words, TSGs encodes protein that act as control or regulator of cell growth.
However, when there is an alteration in the genetic sequence (mutation) of the TSGs, this make the cell not to respond to cues that had been regulating it growth.
Thus, when cell growth is not regulated, it results to runaway or abnormal cell growth (i.e multiple folds cell division and replication), in other word referred to as “cancer”.
