What is the main cause for global wind patterns?

1) currents in the ocean affect the air above it

2) unequal heating of different parts of Earth

3) differences in elevation different landmasses

4) greenhouse gases

(please no guessing)

Competition occurs between species when

Dna replication or repair occurs in a cell in all of thw following situations except when

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
