Question: Cooperative breeding in birds typically occurs when offspring, usually males, delay dispersal from their natal group in order to remain with the family to help rear younger kin. Female offspring rarely stay at home, dispersing over distances that allow them to breed independently, or to join unrelated groups. In general, inbreeding is avoided because it leads to a reduction in progeny fitness (inbreeding depression) due largely to the homozygous expression of deleterious recessive alleles. Cross-fertilization between unrelated individuals ordinarily leads to the masking of deleterious recessive alleles in progeny.
Is there an answer to this question: What leads to the masking of deleterious recesive alleles in progeny?

Answer: Cross-fertilization between unrelated individuals

Question: The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. In 2002, this was more energy in one hour than the world used in one year. Photosynthesis captures approximately 3,000 EJ per year in biomass. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined,
Is there an answer to this question: The amount of solar energy per year is twice as much as the energy that will ever be produced from what resources?

Answer: coal, oil, natural gas, and mined uranium combined


Question: The immediate nationwide uprisings against the new government began by the 1979 Kurdish rebellion with the Khuzestan uprisings, along with the uprisings in Sistan and Baluchestan Province and other areas. Over the next several years, these uprisings were subdued in a violent manner by the new Islamic government. The new government went about purging itself of the non-Islamist political opposition. Although both nationalists and Marxists had initially joined with Islamists to overthrow the Shah, tens of thousands were executed by the Islamic government afterward.
Is there an answer to this question: The new Iranian government purged itself of what political opposition?

Answer:
non-Islamist
