Answer:
The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.

Explanation:
Recessive traits don't show unless both parents have at least one allele for that trait, so if both parents do have 1 allele, the offspring would receive a pair of alleles for that specific trait and would display that trait.

Explanation:
The right answer is Asexual reproduction produces offspring that are identical to the parent.
Sexual reproduction is ensured by fertilization, that is to say by fusion of male and female gametes giving an egg (or zygote). This reproduction allows the maintenance of a genetic diversity within the populations, because it ensures the genetic mixing.
Asexual reproduction (sometimes vegetative propagation) refers to all other means of multiplication in which neither gamete nor fertilization occurs. In this case, the sex of the parents and the descendants remains identical, because only the mitosis ensures the transmission of the genetic information to the new cells. It is a form of natural cloning.
