Answer:

In babies born with congenital defects during the German measles rubella epidemic the specific cause of these birth defects was most likely the development of rubella virus infections in embryos.

Explanation:

Options for this question are:

1. The development of rubella virus infections in embryos. 

2. The failure of zygotes infected with rubella to develop

3. Mutations in the nerve cells of pregnant females at the time of the rubella epidemic .

4. An increase in the amount of time needed for healthy embryonic development.

Rubella is a viral infection caused by a virus of the genus Rubivirus, considered highly teratogenic during the phases of pregnancy where the embryo and the fetus are developing, that is, before 20 weeks of gestation.

The virus is transferred to the embryo or fetus by the mother's blood, acquiring the disease, which can cause abortions or visible malformations at birth, which is called Congenital Rubella Syndrome (CRB).

CRB is responsible for producing cardiovascular, renal, neurological malformations, loss of vision or hearing, problems that German children born during the epidemic probably had.

HURRYY!! Why have American's portion sizes become larger in the last decade?

Viefleur [7K]

Answer:

American's portion sizes have become larger in the last decade due to the expanding of food industries and marketing campaigns that tell us to eat more.

Explanation:

The growth of food industries in the last decades to obtain more money in combination with the media influence has led us to eat more, thus why the size of our portions has increased their size.

Another theory states that people always want to eat more, and the industry has only fulfilled this demand, but it is not clear why, in the past, this did not happen.
