Answer:

d) folic acid

Explanation:

Neural tube defects (NTD) are birth defects that occur in some specialized regions such as the brain and spinal cord. They are considered and bethink as  a complex disorder because they are caused by combination of environmental and multiple genetic factors. Environmental factors include low folic acid intake, maternal use of certain anticonvulsant medications. etc. On the other hand multiple genetic factors can include spina bifida (an phenomena whereby there is incomplete closing of the spine and membranes surrouning the  spinal cord at the  initial stage of development of fetus in pregnancy.

During pregnancy, folate requirements increase due to the result of rapidly dividing cells related to fetal growth. It is of great advantage that pregnant woman should increase their folic acid supplements intake to (400-800μg daily)  prior to conception, this  can help and assist to reduce the risk for neural tube defects in the fetus.

A restriction enzyme: Please choose the correct answer from the following choices, and then select the submit answer button.
Dimas [21]

Answer:

e. All of the above.

Explanation:

  • A restriction enzyme or restriction endonuclease is an enzyme that nicks or cuts DNA on a specific location after recognizing a specific sequence.
  • Restriction enzymes are widely used in cloning and biotechnological procedures.
  • The step of recombinant DNA technology requires the acquisition of the gene of interest (GOI). This is done by cutting it out of the donor genome.
  • Restriction enzymes perform this task by cutting on specific sequences. One important characteristic of restriction endonucleases is that they introduce "sticky ends" or overhangs in the donor sequence so it can be easily incorporated into the vector.

Answer: B - transports oxygen and carbon dioxide for the respiratory system
The cardiovascular system consists in the heart and all blood vessels. Blood vessels lead the blood from the heart to the rest of the body and then brings it back. It's in the lungs, part of the respiratory system, where the gas exchange is going to happen. What that means is that oxygen is going to enter the blood while the carbon dioxide needs to be eliminated.
(If the option A, said carries hormones FROM the endocrine system, that would be also correct.)
