<span>The evolution of plants has resulted in widely varying levels of complexity, from the earliest algal mats, through bryophytes, lycopods, and ferns, to the complex gymnosperms and angiosperms of today. While many of the groups which appeared earlier continue to thrive, as exemplified by algal dominance in marine environments, more recently derived groups have also displaced previously ecologically dominant ones, e.g. the ascendance of flowering plants over gymnosperms in terrestrial environments</span>

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:

<em>1. </em><em>The development of rubella virus infections in  embryos. </em>

<em>2. The failure of zygotes infected with rubella to develop </em>

<em>3. Mutations in the nerve cells of pregnant  females at the time of the rubella epidemic .</em>

<em>4. An increase in the amount of time needed for  healthy embryonic development.</em>

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.

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

Which statements accurately describe humidity? Check all that apply.
Scrat [10]

The correct answers are:

B. Warmer air promotes more evaporation.

D. Humidity refers to the amount of water vapor in the air.

E. Areas with a lot of surface water have higher humidity than drier areas.

The humidity can simply be described as the amount of water vapor in the air. The humidity can vary, and it can be very high in certain place for the whole year, very low at other places for the whole year, or to be changing seasonally.

The areas that have a lot of surface water (the Amazon River Basin) tend to have higher humidity than the places that lack surface water (Sahara Desert). Also, the humidity depends a lot on the temperature of the air. The warmer the air is, the higher the humidity, and vice versa, the colder the air is, the lower the humidity.
