Answer:

C. The region that codes for RNA unfolds.

Explanation:

Chromosome represents packing of DNA with help of histone and other proteins. Tight packing of DNA and condensation into chromosomes make the RNA coding region of DNA inaccessible for RNA polymerase resulting in decreased rate of transcription. On the other hand, loose packing of DNA with histone proteins and unfolding of chromosomes expose the RNA coding region for enzymes and factors of transcription leading to increased rate of transcription.

a german measles rubella epidemic during the years 1963 to 1965 resulted in approximately 30,000 babies being born with birth de

Juli2301 [7.4K]

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.

Where should the biosphere label appear in the system model? Use reasoning to explain your answer.

Leto [7]

Answer:

Biosphere is the one of the sphere of geological sphere of the earth such as geosphere, hydrosphere and atmosphere. It is deal with the interaction and existence of the living organisms.

In this model it can be seen that there are human, fishes, and vegetation of plants are living organisms so living organisms in the hydrosphere (fishes), geosphere (plants) and anthrosphere (human) should be label as biosphere instead of atmosphere or with atmosphere.
