Answer:
Rubella.
Explanation:
German measles is a viral infection that causes red rashes on the whole body of an infected person. The disease can be easily spread from infected people to healthy people by sneezing or coughing.
The German measles is caused by rubella virus.Rubella virus contains single stranded DNA as its genetic material. Rubella virus causes fever and swollen lymph nodes in infected individuals.
Thus, the correct answer is rubella virus.
Geneticist is a scientist that studies dna
Answer:
New allele combinations are acted upon by natural selection.
Explanation:
Recombination may be defined as the process of the exchange of the genetic material between the homologous chromosomes of the non sister chromatid. The combined trait will be visible in the upcoming generation.
The recombination allows the generation of the new genes in the population. These new genes if beneficial for the population will be pass to the next generations. The new allele will be favored by the natural selection and increases the chance of survival of the population.
Thus, the correct answer is new allele combinations are acted upon by natural selection.
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
Hope this helps!
