Answer:
Yes earth is only so big
Explanation:
SUPOSSEBLY IN 2035 we will have a small civilization on mars. Cause in 1 million years or less humans will be over populated on earth and forced to make room underground or higher in the skies like outer space!
Conjugation - this is when bacteria exchange genes among each other. Sexual reproduction is when genes from the male and female are fused to create a new diverse zygote. Bacteria can do a similar process by conjugation.<span />
Geothermal energy for heating. Solar power, or HydroElectric energy. The most efficient/Ideal one would HydroElectric energy. The reason why I say this is because HydroElectric energy does not pollute the environment, or produce harmful fumes. It also produces a lot of energy to power multiple homes.
This allows for humans to breed in the same genes and have the same characteristics as the people in their geographic location for example how Asian people share common characteristics with Asian people. But they differ from European people.
Sexual production is a means of recreating more of a species. Once there is a gene change whether for the good or bad, and solely if the organism survives to reproduce its gene, then it will be passed on to its children and going further on until there is a large amount of a species with that specific gene. This species evolved. Evolution occurs because of gene changes.
