False like blood lymph won't flow both to and from the heart
Answer:
True.
Explanation:
The unequal distribution of ions inside and outside of the cell makes the membrane potential of the cell. The potential is important for the conduction of the impulse and generation of the action potential.
The resting membrane potential of the nerve impulse is maintained by the presence of large potassium ions inside the cell. The resting membrane potential is -70mV. The depolarization of the membrane occurs due to influx of the sodium ions.
Thus, the answer is true.
Dominant' traits will actually disappear faster if they are disadvantageous.
Think about it: if everyone who has even a single copy of a particular allele is at a disadvantage (manifests the phenotype, in this case six fingers), then even single copies are selected against.
In the case of recessive traits, selection occurs only against homozygous carriers, who may be very rare if the allele itself is rare.
A concrete example would be something like Tay-Sachs disease. If the allele that causes this were dominant, every carrier would die before adulthood, and it would occur only as a very rare de novo mutation. But because it is recessive, it persists for now; heterozygous carriers have no disadvantage.
Answer: Can you, please, explain what experiment?
Explanation:
The nurse should include in their discharge notes to the couple the different ways they may access to guarantee birth control.
They may continue to use barrier methods which are the most safe when it comes to not disturbing any hormonal balance or intervening with the milk. Condoms for men are usually the most easily accessed to.
Besides the barrier methods, there are also the hormonal methods. When breastfeeding these are not the most used methods. There is a special pill, progestin-only pill, that is the most appropriate because it doesn't affect milk supply when taken after 6 to 8 weeks after the birth. All hormonal methods should be taken always when counselled with the doctors.
