Answer:
calcium channel close.
Explanation:
In action potential there is phase 0, phase 1, phase 2, phase 3 and phase 4. In phase 3 of action potential there is a rapid repolarization phase in which calcium channels remain closed but potassium channels remain open and continuous outward movement or leakage of positive ions causes the outside environment positive and membrane potential goes to negative charge that is -85mV to -90mV

Explanation:
Otitis media is inflammation in the middle ear. Otitis externa is inflammation in the outer ear- external like “externa” is usually referenced as something “outside”.
Answer:
Explanation:
Hemophilia is a X linked recessive genetic disorder caused by low amount of clotting factors. Hence, it becomes difficult to stop bleeding in case of an an injury and takes more time to clot. Here,
c= recessive allele for hemophilia gene
C= dominant allele for hemophilia gene
Genotype of male: XcY since he carries the recessive allele for hemophilia trait
Genotype of female: XCXc. She does not have hemophilia but her father had hemophilia so she she must have received one X chromosome from him and hence is a carrier for hemophilia.
Their children:
XcY X XCXc = XCXc, XcXc, XCY, XcY
Out of resultant genotypes 2 out of 4 i.e. XcXc and XcY show hemophilia trait hence there is 50% probability that the child will have hemophilia.
