For most women, the American Academy of Pediatrics recommends exclusive breast-feeding for the first 6 months of the baby’s life

Naily [24]

Answer:

3- Breast-feeding can reduce an infant’s risk of infection, allergies, and certain chronic diseases.

.4- All mothers should consume 500 kcal extra daily while breast-feeding until weaning of the infant.

5- Women with AIDS or active tuberculosis should feed formula rather than breast-feed.

Explanation:

Breastfeeding is also a great benefit to the environment and society, that is, it does not require the use of energy for manufacturing or create waste or air pollution. Also, there is no risk of contamination and it is always at the right temperature and ready to feed. Given the importance of breastfeeding for the health of mothers and babies, Centers for Disease Control and prevention supports breastfeeding through hospital initiatives, work-site accommodation, continuity of care and community support initiatives. Colostrum is the earliest breast-milk produced, beginning in mid-pregnancy (12-18 weeks) and is continually produced for the first few days after baby's birth, it provides all the nutrients and fluid that your newborn needs in the early days, as well as many substances to protect your baby against infections. Mothers with untreated and active tuberculosis infections are not advised to breastfeed. They may breastfeed after their infection is cured or brought under control so that it does not spread to the infant.

Which diagrams shows reaction pathway that absorbs energy?

postnew [5]

Question:

<em>The diagram shows the potential energy changes for a reaction pathway.</em>

Part 1: Does the diagram illustrate an endothermic or an exothermic reaction? Give reasons in support of your answer.

Part 2: Describe how you can determine the total change in enthalpy and activation energy from the diagram and if each is positive or negative.

Answer:

Part 1: The diagram illustrates an endothermic reaction as the products has a higher potential energy than the reactants do. There is a positive slope of the diagram and there is enough energy to meet the activation energy requirement.

Part 2: You can determine the total change in enthalpy and activation energy from the diagram by the potential energy of the reactants. If the reactants have a high potential energy, then the enthalpy is also high, and if the reactants have a low potential energy, then the enthalpy is low. You can determine if the diagram is positive or negative by knowing if its an endothermic or exothermic reaction. An endothermic reaction is positive because the products are higher than the reactants and a exothermic reaction is negative because the reactants are higher than the products.
