Answer: e. prokaryotic cells lack nuclei.
Explanation: Prokaryotes are unicellular (single-cell) organisms that lack well developed cell internal membrane-bound structures or organelles. They do not have a nucleus but generally, they have a single chromosome that possess a double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane.
Answer: Folate can prevent birth defects of the baby's brain because it helps to form the neural tube.
Explanation:
<u>Folate is the naturally occurring form of vitamin B9</u>. After its intake, the digestive system converts it into the active form of vitamin B9 that will eventually be used by the cells to perform different functions. Basically, the body uses it to make new cells, because<u> it is vital for cell growth and development.</u> It is an important part the diet and it is also important during pregnancy. This is because it helps prevent neural tube defects such as anencephaly or spina bifida among others that occur when the spine and brain of a baby do not develop completely.
