Answer:
Placental detachment.
Explanation:
In the final stretch of pregnancy, vaginal bleeding tends to worry doctors and mothers a little more, as it arouses suspicion of placental detachment - a serious condition that can lead to bleeding and disrupt the flow of nutrients and oxygen to the child. Depending on the situation, the doctor may need to have an emergency caesarean section. If the detachment is only partial, however, it is possible to proceed with the pregnancy, provided that medical follow-up becomes intensive.
Answer:
True
Explanation:
This process is called Chemiosmotic Theory.
Two different solutions with a semi-permeable barrier (it allows to pass throw just water or solute, not both) will try to get into equilibrium.
Then, if you allows to pass just water though the barrier, it will go from the solution with less solute to the solution with more solute, in order to reach the solution equilibrium.

Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
