An increase in earths temperature from the build up of carbon dioxide and other gases in the atmosphere is called... global warming, transpiration, ozone depletion, eutrophication

Genes that come together with different alleles are heterozygous. homozygous. genotype. segregated.

When fossil fuels are burned, carbon dioxide is released. how does this gas impact the environment?

Cells a and b are the same size and shape, but cell a is metabolically quiet and cell b is actively consuming oxygen. oxygen will diffuse more quickly into cell because . b the oxygen molecules inside cell b have a higher kinetic energy b. a its membrane transport proteins will not be saturated c. a the diffusion gradient there is shallowerd. b the diffusion gradient there is steeper
