<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
<span>All children have a 50/50 chance of being male or being female. There is no true predisposition of having all male or all female children because it depends on the strength of the sperm and which sperm reaches the egg first. If the stronger sperm is an X chromosome sperm cell the child will be female while if the Y chromosome sperm cell is stronger then the child will be male. With women it does not matter because women have 2 X chromosomes versus men who only have 1 X and 1 Y. So the probability that the second child to b born a male will be 50/50 just like any child that is born.</span>
My guess is probably South America and Africa
Hope I could help
Answer:
Explanation:
Pericentric inversion results in chromosome have extra copies of some genes while some genes do not have copies. It can result in slow growth rate.
If a man is heterozygous of pericentric and a woman is heterozygous of pericentric although they do not show symptoms there is 25% chance that their offspring will have it and 50% chance of them being a carrier.
T t × T t will give TT T t T t t t
If the father is not heterozygous of it but the mother is heterozygous they have 0% chance of having it and 50% chance of being heterozygous a carrier of the disorder
T t × TT will give TT TT T t T t
