Answer:
Folic acid
Explanation:
The congenital neurologic abnormalities refer to the abnormalities which are present in the infant at the time of the birth like neural tube defects in the given question.
There could be many factors responsible for this like consumption of drugs and alcohol, exposure to mutagens or carcinogens, inadequate amount of folic acid and many others.

Thus, Folic acid is the correct answer.
Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
Answer:
Because it is a vector quantity, it has a direction too such that derived unit is made up of two or more fundamental units. That is mere and second. That is why it is called as a derived unit as its unit is metres per second.
Hope this helps...Have a good day!!
Answer:
- T. Natural Reseeding.
- D. Species Diversity
- A. Ecosystem Diversity.
Explanation:
Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.
Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.
