A woman who is breastfeeding is not able to eat enough food for two weeks because of a lack of money. What effect will it have o

NikAS [45]

Answer:

There will not be any effect because the body will continue to produce enough.

Explanation:

Producing breast milk to satisfy a starving newborn is an arduous and energy-intensive task - about 500 calories a day. Therefore, it is important that moms a little more than normal. If the mother eats little, her body will still produce good quality milk, but she will run out of energy. This can also slow the recovery of your body after childbirth.

What determines milk production is how often the baby breastfeeds or how much more the mother empties her breasts. That is, the more the baby suckles, the more milk the mother will have. This milk will always be the amount of nutrients a baby needs, regardless of whether or not the mother has eaten. But if the mother does not eat, she may have health problems.

Explanation:

As shown in the animation from my school, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes.
