An example of an ecosystem that benefits people could be the ocean.
The ocean regulates the temperature of the earth, allowing a more comfortable place for people to live.
Hope this helps!
You need two recessive alleles (xx). If even one dominant allele is present, the dominant trait will show (Xx or XX will both result in the dominant trait showing). That’s why they’re called dominant traits, because they overpower the recessive traits. In order for a recessive trait to show you must have two recessive alleles.
In DNA, the nucleotides of one strand join to bases on the complementary strand by weak hydrogen bonds.
